12:29 - It actually DOES support saving! It makes use of the regular cartridge save built into games like Pokémon. Save states in the emulator itself are not supported though.

Hey, thanks for featuring my emulator! It definitely shows its limitations on this hardware, but it's kind of crazy that I was able to get it working at all, haha.
I also thought I would point out that despite what that review on ticalc says, the emulator does have a save function, but it's only for the cartridge save and not save states like that user was probably expecting.
Hey! Thanks so much for clarifying that! I'm pinning this so that people can see
I just want to let you know that my entire AP Calculus class has your emulator and a handful of roms on our calculators. You're a blessing to us all.
my entire class has been using your software for years you are a legend
good job man!!
I was actually about to leave a comment asking why the emulator would make a note about 'not having enough space to save' if saving wasn't possible, but this clears that up. Thanks!
"They are still expensive, but I am not going to go into that today"
Got me all fucked up now, can't believe I have to do my own research
Did u figure out why lol
I was selling one of these calculators at a flea market for $10, many people walked over. picked it up, looked at it very hard, and then left!!!
LGR has a video about it. It's the latter of a two-part episode of "LGR Tech Tales". It has to do with bribing math teachers.
@@UndergroundLookingUp recently got one of these free - it was discarded because the pins to the battery needed to be bent back slightly at the board which is a common problem with these
@@cs8712 Nice deal! When one knows how to fix the simple things that go wrong, there is a bounty of treasure to be had.
I remember getting in trouble with the teacher so many times for playing games during math class on this thing!
These graphing calculators were my first introduction to programming. I am now a senior software engineer.
I'm a senior engineer, as well. Never trust a programmer with a calculator in school. I may or may not have coded a cheatsheet program on my calculator that autocleared the screen on any button press... 👌🔥
Epic
your comment says "10 hours ago" when the video was released 6 hours ago
These calcualtors were also my first entry into programming. I completely remade the old drugwars game from scratch with different features.
@@islandslandbro hacked the matrix
I got solitaire on my graphing calculator and played it when waiting for time to be up on the SATs
14 hours ago? wtf?

back when I was in high school, my math class had some. However, the rule was that if anyone played games on it they would fail the class
My favorite piece of software on that site is Fruit Ninja, which emulates the iPhone game surprisingly well by having you swipe your finger across the mass of calculator buttons. It's also one of the few games that actually plays better on a TI-83 Plus than a TI-84 Plus (since the 84 Plus has concave buttons that are harder to swipe over in an uninterrupted motion).
That is such an interesting control scheme!
It's pretty incredible to see Game Boy emulation on something that's barely faster than a Game Boy to begin with.
It's not even faster 😂
@@NathanGreway Well, the Game Boy has a 4 MHz CPU, the Ti-84 has a 15 MHz CPU. Though the Z80 that's in the Ti-84 is a significantly older design, so that might make the higher clock speed a bit misleading.
@@NathanGreway Actually, the CPU is about 3-4x as fast as a Game Boy's, but it has no hardware accelerated graphics so that cuts into the processing time for games quite a bit. And as far as the Game Boy emulator goes, the overhead of emulating a different (though similar) CPU does more than cancel out the extra speed.
I considered implementing a JIT recompiler, but these older calculators didn't have enough memory to cache the recompiled code. In the successor emulator on the TI-84+CE, I finally had enough memory for a JIT, which is one reason that emulator runs far better.
@@calc84maniacfascinating, thank you for sharing! I've always wondered if this was using emulation for every instruction or if the Z80s were similar enough to only require emulating the graphics
@@clebbington Right, while they are similar, they're different enough that it's not possible to run the code directly (and even if the Game Boy had a real Z80, it still might not be possible due to not being able to intercept its hardware interactions). But the similarities do allow decreasing the emulation overhead by quite a lot.
This is really weird timing. I had a dream last night that I was playing Pokemon on a calculator. The pixel grid was only tall enough for like 2 or 3 lines of input at once but somehow that was enough space to make Pokemon playable lol

Now that's a name I didn't expect to see on this channel
look mom, I'm on the you tubes
When I was using a TI-85 since 7th grade in 1997, I only learned enough TI BASIC to automate stuff like quadratic equations and the Pythagorean theorem. I was never able to properly connect my calculator to my Windows 95 computer at home to do any transfer of anything to or from it, so I never even bothered learning back then that the flavor of assembly that was used was Z80 and would've eventually made Game Boy emulation possible, even at reduced speed.
15:41 AKA "Speedy thing goes in, speedy thing comes out."
I got the TI-86 the day it came out and used to sit in math class typing z80 opcode programs into the asm() function. And frequently locking up my calc and having to reset it. It was glorious. I had an -85 bebefore that - but the official support for assembly on the 86 was mindblowing.
Reminds me of when I hacked my TI-Nspire II to cheat during my AP exams, and to play Pokémon Fire Red during the break. The next year I played Doom during the break. I failed both AP exams…
Lol. Sorry, but just... Lol.
That Portal game is basically a calculator version of the Portal flash game I love it
50 cents worth of compute being sold for over a hundred dollars. It totally makes sense.
It's why if you can swing it, convince your teacher to let you use your handset. It's a graphing calculator in your pocket, and if you can set that up within a day using any computers available to you, then you can save the hundo and show the teacher your handset is perfectly-capable for the task.
Amazing video Michael!
i think this is my favorite mjd video! i remember being super into calculator programming / jailbreaking a few years ago, and i actually managed to boot the linux kernel on a ti nspire. great video as always, much love ❤❤
gay. so gay.
ofc u ran linux on a calculator gayfemboyuwu, i bet it was arch linux gayfemboyuwu
@@arubberroomwithrats it was not arch 😭 just the kernel
@@arubberroomwithrats i run arch on my pc tho uwu

i love you michael!!!! i wanted to try this for years!!
So cool to see these projects that people have made for these graphing calculators over the years... It's impressive work
If anyone wants to play with TI software, there is actually a TI-83 emulator called Wabbit. I don’t know how it does recent calculators, but it got me through college on my phone.
That's what I used. Screw buying some other useless piece of tech.
0:02 Raise your hands if you used one of the predecessors like the 83+ (or older even!) 👋👋
Me
My brother did a side “job” downloading games into calculators and I played one during my free time
I spent hours upon hours in highschool in the late 90s programing Basic on my TI-85.
I got a Python version before even high school. Unfortunately it doesn't have assembly (and because of complaints from teachers iirc), and I learned the hard way trying to run a port of Bejeweled.
But, I did have fun playing BASIC games during Algebra 1, and I do know a fair amount of Python myself, so I could just code some simple Python game if I was bored, or maybe automate some of my work if it's a simple concept for me.
TL;DR - As my calculator had Python instead of assembly, it's nice to see what the older models could do.
the real nanami madobe is here
You could run Python on that thing?!
@@theeblueguy__FR
@@LandonEmmaI'm guessing their late gen z or older gen alpha as only the newer calculators do python.
@@qwertykeyboard5901 I'm from late Gen Z
Nice! More of such stuff please😀

2024: GameBoy and Portal games on a Graphing Calculator!
11:50 Pixelated sound
My school dictated we had to use Casio 991 fx non programmable calculator but great too see this regardless.
I had the TI-83 plus in high school, I really wish the TI-84 came out earlier because I already graduated school when they released those models. But I did download some games like Mario Land to my TI-83 calculator from a peer to peer connector from a friend’s calculator in class! My younger cousin who got the TI-84, she had puzzle games on it. And now there’s color TI-84 CE which are really cool and used for downloading bigger games, but lot of math classes are banning color graphing calculators due to its distractions.
WOW!
I got a box with at least 7 calculators bought cheaply from a local online marketplace. People place their stuff their, broken or not.
I simply bought calculators with problems, fix them, and they stay with me for nostalgia purposes.
It happens I bought a Ti-84 PLUS silver edition. It didn't start with the 4 batteries, So I had to open the Ti-84... much harder than TI-83... and it happens the ground contact was corroded on the board where the metalic piece lands.
Fortunately the huge ground contact has ground all around. I just cleaned the corrosion and I also had to clean the rest of corrosion dust.
I also soldered a wire from the ground contact on the board to the metallic piece of the negative pole of the battery.
Texas instruments had lots of problems with corroded boards but they stupidly continued making them. Ti-nspire has also this problem.
The metallic piece reacts with the copper ground/vcc and some calcs simply turn dead and users sell them or throw them to trash/drawer.
Oh wow Mini USB? What a luxury! 🤣 Who remembers the Graphlink USB and Link Cables? Older TI-83s could ONLY use the headphone-like port at the bottom for data transfer between either 2 calculators or a calculator and the PC. I remember when I was in middle school, we'd all share whatever games we had (or came up with ourselves) with each other via link cables at school.
My school has plenty of these. I used to fidget with the apps on these things during Math class. I remember using a coin flip app and trying to cobble together a program of my own on the calculator itself.
Out of necessity, I ended up learning how to program my own stuff for my engineering classes. These calcs use a rudimentary form of basic, so you can easily program stuff like vectors, conversions, or whatever. The TI calcs are all a little different between them. So for example, the TI-81's are hard to program for. The TI-83's are a lot more forgiving and the TI-83 plus's have a lot more memory.
Ironically, I never tried a game on my calcs. I want to try that Portal game though.
Back in high school (circa 2003) a guy I was friends with had super mario bros on the first model of these. Despite owning a GBA I still thought it was the coolest thing.
I remember using Mirage OS back in the day, but I don't remember a full blown gameboy emulator, it might not have existed yet, that kind of blows my mind though. I did play a Pokemon red and blue port made especially for the calculator, it had really minimal graphics, didn't even have sprites for the pokemon, and you could only attack based on the pokemon type. It was a super simplified version of the game but even so I played it to the end, anything to escape boredom at school lol.
When you use it for school until August.
Man, I wished I had one of those. I used my uncle's hand-me-down TI-55 III in college.
Luckily my Philippine college didn't require a TI-84 like I've been told certain colleges and universities and high school standardized tests in the US do.
Wake up NEW MJD VIDEO
I love that the TI connect screenshots are still windows vista/7 .
I love mjd videos ❤🎉
I have bad time 😢 but I’m from Australia
Cool project
I had Mario on my TI83 in 2006. Life was good.
I've never used graphing calculators at school, only regular scientific ones. However, a few years later I worked there for some time and one day I had the task of testing and replacing batteries on a bunch of Casio fx-CG20s and fx-CG50s. I also took the opportunity to upgrade all of them to the latest firmware. I think those are ARM-based or something 32 bit, while the TI-84 is still stuck on the Z80.
I had a Dark Blue TI-81 I Picked Up at a Garage Sale somewhere in KidRock Country for $5.00, Probably around '95.
It didn't have a Serial Port at All if I Remember Correctly.
I could Program BlackJack & d0PeWaRs from Memmory.
But Nobody cared as they all had Money to show off their Awesome TI-84s, Which had a SMB Clone that worked Really Well in '99
You are correct about the TI-81 not having a serial port, or any ports
gonna try this on my Ti-84 Plus CE
I didn't have a TI 84, but we had Voyage 200s (2002 release of the TI 92), which are way better imo. I absolutely loved their form factor
I had one of those also (in addition to the 92 that I upgraded with the plus module) the voyage 200 was soooooo good
“What’s 8x96^2?”
“ *PORTAL* ”
I love how he can just do like anything
I grew up in the TI-82 era, transitioning in the the TI-83. I still have my TI-82. My parents must've gotten it for me in 1994, I believe. Certainly no later than 1995.
if any of you want to try this, the TI connect software doesent always work on some computers. You can use TI connect CE (works with non color edition too) and I had no problems with that.
Please we need more videos about graphic calculator
This is cool.
Nice!
Now I want one of those fancy calculators
Just fyi, you can actually tell between the portals in portal prelude, the fastest moving portal will disappear first, and to switch between which you're firing you press the 5 key
Whenever I see a TI-84, I can hear E1M1 playing in my head.
I hear that every time I open my bathroom door.
Man I need this for when I'm bored in class
Do not forget to remove the batteries if the calc is not in use for a long time, like a week or 2. Even if it's not in use, the internal clock and the internal stand-by still eats power. I left 4 new batteries inside for a month (1.6v each) they simply gone to 1.4v.
Should probably do this in mine
Request:KinitoPET-A digital virtual pet who loves me
I have vague memories of playing Pokemon Blue on my personal TI-84 (fun story, I got it for 2 bucks!) while in geometry
Someone got 3D Minecraft working on a TI-84+ CE. I played it during math class until school ended for summer break
I wonder if these all games also work with TI-Nspire with TI-84 keyboard. The TI-nspire with ti-84 keyboard turns the first gen ti-nspire into a bit giant ti-84 plus silver but it doesn't have for example the mode alpha s diagnostics.
Some games don't work in TI-Nspire with TI-84 keyboard because TI's emulation of the system was a bit lackluster. For example, they didn't implement any undocumented Z80 opcodes because their OS didn't use them, so it would cause a RAM clear if one of them executed. TI-BASIC games like that Mario Party game would have no issues, though.
You should try the TI-84 Plus CE. It can emulate Game Boy Color games, and maybe GBA games. Not sure if there is sound though.
i have done this! :D
Well I know what I'm doing with my TI-84 Plus!
Graphing calculators are one of the only relevant retrocomputers today for non-nostalgia.
My mom was a math teacher. She would have representatives from TI come to teach them on how to use it with their curriculum. One representative told her that the graphing calculator part of TI's business was so small and such an afterthought that they'd forget to take roll call of that division at TI's conferences 😂
i have a ti 84 plus silver edition to this day i got it after high school (graduated in 2015)
Nice video
It released 3 minutes ago dawg
@@rubrumlol i am watching it right now
Teacher: NO PLAYING ON YOUR PHONE
Me: *plays on calculator*
Teacher: *O*
I’m pretty sure the cpu in the TI-84 is based on the Zilog Z80, the cpu in the Sega Game Gear
You should check out the HP Prime next! It's a damn beast compared to even the TI-nSpire nonsense. Very good build quality too.
Wait, how can the gameboy emulator have sound support?? I have that exact TI-84 and any other old school TI, that I know of, have no speakers or anything. How can it output audio?
You have to use the 2.5mm jack on the top to plug headphones into.
@@MichaelMJD And since that jack was designed for data transfer, it has no DAC so it's only capable of outputting 1-bit (stereo) signals. That's why even outputting 4 channels at all is kind of complicated and requires some extra CPU usage, which combined with the already slow emulation gives some not-so-appealing results.
Cool!😮😮
The tetris theme sounds like u just got a copy of it from the homeless man in the back alley and now the demons are in the house
I GOTTA SEE DIS
I used a TI-83 Plus in high school
I have a TI-30. Got it back in the day when Office Depot had price match. Got it for $10 under MSRP. Haven’t booted it up in forever. Batteries might be corroded. Or it was Walmart price matching and Office Depot had it cheaper
Hey, I have a video idea for you just like you installed iOS 15 beta now can you install iOS 18 beta on your iPhone 11?
I don't have my iPhone 11 anymore, but I have been thinking of doing a video on the developer beta!
@@MichaelMJD Oh right I remember you traded that
I had a TI-83 Premium CE. Put OIRAM and Chess on it lol
I use that at my school as a senior
Oh Michael! Ironically.
While Tetris for the GB WAS programmed to have highscores and whatnot... They never put a SRAM/Battery on the board... So the function just don't work!
Or maybe it could on an emulator!
I recently bought a TI-84 Plus Silver Edition from a Savers and I ❤ it!!!
11:53 reminded me of "Acid Tetris - Simple Song", kinda 🤣
If the video is played at 1,5x speed
That’s the exact model I used in high school
Nice
is that a windows 7 stock pfp
The mini USB cable needs to be able to transfer data btw, some only charge devices
I still need to buy a calc.
Make my day by playing Race Drivin on it. 👍
How do i get ti connect on linux
If only I had this calculator when I was in school...
Hearing about the emulator doesn't support game saves really feels like a bit disappointing, so with battery save support would be perfect!
can it run doom?
Portal prelude looks like an homage to portal flash
*Raises hand* I even learned a bit of TI-84 BASIC
fun fact: if you hold on your keyboard 0 in the video it will look like Michael saying R
When are you going to make another documentary-style video?
fun
I have a ti nspire, it as a arm processor and so powerfull it emulate Gameboy advance with a full color screen. I literally never used it to do math... And I never used it to play Gameboy advance after the first time I tried it.
I had a TI 82 stats in school, and they offered me to buy it afterwards but I didn't want to buy it because it was too expensive for like 20 years old tech, and that was 15 years ago.. 🙄
