- Another Nintendo M82 console was sent to me for repair, this one being a lot trickier than the last to fix. So settle in for lots of boring datasheets, probe beeping and oscilloscope analysis!
Time Lord soundtrack: • Time Lord (NES) Soundt... - Hry
It's so rare to find someone who can simply explain their incredibly complex work in a way that, while I don't understand everything, I understand more after listening.
Agreed trygon. I love old tech and nintendo. This man knows his crap and can portray his knowledge in laymans terms so at least even my nontechnical arse can slightly understand. While expanding my understanding of computational sciences
Seeing him work and his knowledge is like seeing a master artisan, but more fun. The legend is real.
I dare Ben Heck to build a functional NES game playing machine using only spare chips and a mos 6502 or whichever chip the NES CPU actual operates as, bonus points for taking an Atari 2600 CPU chip and adding NES type components (generic ram chips that would work, possibly the only parts I'd really say are acceptable to use from a pre-existing NES system would be the ppu chip , the cartridge recepticle, and the MCU that ensures the cartridge is authorized (possibly also any ROM chip necessary for an NES, if any exist. (My knowledge on NES hardware components is limited, but I'd love to see Ben Heck going through and troubleshooting his way into a working game cart player by attaching a game cartridge and fixing any issues as he has in the past with handheld conversion projects and / or how he figured out how to make banking carts work on the UK m82... I'd love the video he could make from that. If he doesn't want to , no pressure, obviously, but it sounds cool as an idea in my head...
That was better than an episode of Matlock
@@seanabsher5577 Well the CPU contains most of a MOS/CSG 6502's actual lithography, illegally copied by Nintendo with the patented stuff removed (BCD functions if I remember), and Nintendo added some NES-related functionality (possibly just sound). So using a bone-stock 6502 might not be doable...
@@CommodoreGreg stock 6502 + audio hardware and other chips and etc to make it do the job? Or would it actually need an NES CPU just to do the work? Seems like a stock 6502 + support circuitry could do it
I'd argue that Ben IS a master artisan.
I hope these high end collectors are paying Ben handsomely for his ER work!
actually hes was quite generous with this final price for the repair.
davidevgen his the saint of the retro video game world
@@treedeblue i agree completely :P
@@treedeblue I bet he could have saved AVGN's dead Jaguar CD
@@trankzen148 Yup
It's almost like the company didnt expect these things to be anything but e-waste a few years after they were built.
Might've actually makes sense, since Nintendo probably thought they would be used for a few years at most, then replaced or thrown out. The only reason that some still work is people actually caring about them and fixing them rather than treating it the same way little billy probably handled the controller while his mom did some shopping.
Yes. I was being sarcastic.
@@Pancreaticdefect you must be fun at parties
That's most things in general to be honest. Arcade games being a great example, for every one that exists five others were thrown in a dumpster after the operator made their money.
@@BenHeckHacks speaking of arcade PCBs any chance we'll get to see a repair of one on the channel ever?
A good cart to test mirroring is Metroid, it switches every room.
Did not know that one. Thank you, i learned something new today!
Wouldn’t MegaMan Switch in the same way? On a few stages it switches from horizontal to vertical like Ben showed in the video?
I appreciated the thorough walkthrough of your debugging process. As an amateur in to electronics I found it easy to follow without being dumbed down or skipping major steps.
Hey! Guys! I think this Ben guy might know a thing or two about video game consoles.
I think he has Video GamenNES
He is a legend !!!
Excellent knowledge of 8 bit microsystems. Very good diagnostic thought processes. impressive work
Ben? Who the heck is this Ben you are referring to?
He also knows a thing or two about printed circuit boards.
I told my wife about your Butter Bass reference, and she laughed because we call it Daniel Fish for absolutely no reason. Seems giving irritating enemies random names so you can reference them is universal!
Time Lord soundtrack was written by David Wise. That's why its awesome! lol. Wish I had your electronics knowledge. Its truly amazing to watch you work on something.
These videos are super relaxing. They smack an ASMR itch. Except those loud beeps hurt my ears but they’re still kind of music to my ears
That adventures of Bayou Billy part cracked me up. That was accurate XD
hhahaha
Ben Heck is a genius, no doubt about it. The demo units are working now, all right. Still, my crystal ball predicts somewhat sparky future for these devices. An uninsulated metal heat sink fastened by a bag closing tie, the long uninsulated resistor legs almost touching the pins of the module connectors, as well as dremeling a screw head to metal dust over the unprotected circuit board in the another M82 video made the temperature of the room sank at least by 10 degrees. The dark side of the Force must be running strong in this channel.
Talk about perfect timing. I just finished getting caught up earlier today, ending with Ben saying he's got another M82 to fix!
Your businesses card should read: Ben Heck : Console Whisperer.
I'm the one who sent this m82 in. the issue still persisted that i was having after the unit came back to me. all the graphical issue in this video was not related to the issue i was having in this video. so after the disappointment of the issue i was having still persisting i bought another m82 (pal b unit) from Germany. and converted it over to NTSC however i noticed one difference that my m82 didnt have and that was four 103 ceramic capacitors that were directly connected to 4 buffer chips in the front center of the board. (a hot fix by nintendo on later models)
so i ordered those same caps and attached them to my old m82 motherboard buffer chips and that fixed the graphical issues. 4 years 2 others working on the unit and 1000 dollars later i finally fix it. i wish i had known that was all it took to fix it in the first place. Anyways thanks for trying Ben heck.
Loving the video, some of it went over my head but your humor kept me watching
Damn man, you went so many levels deeper than I ever could on that retro hardware debugging, and I thought I had a knack for it.
address bits level. it's no trivial task. although a ground shorted address bit made perfect sense since the beginning, but as in the Nintendo Playstation prototype episodes (mainly faulty elec caps which led to a previous mod that disabled the CD drive), everything is dead simple once you're being told about it. But getting to it is not as easy.
Fantastic work and very enjoyable video.
I think what I enjoy most about your videos is the way you always have that relaxed attitude and humour in your approach. The subscribe song was excellent.
Heck Mr Heck , your vlogs are captivating. I don’t know if it’s your character/charisma or the knowledge you are sharing with the virtual reality world & I know absolutely nothing about computers other than turning them on , so it must be the latter , keep on doing you , for all those kids that will be transfixed & inspired by watching this , I think you’ll be amazed how many over the life of the WWW , this is teaching to the future , to see into affinity & beyond
I didn't understand nothing about the eletronic stuff, but it's akways a joy to watch Ben's work. Greetings from Brazil! :D
@28:22 the burning question for my childhood gets answered, thanks ben!
These videos are gold :-)
A lot better than the show due to it being a lot more in depth!
Thanks.
This thing is awesome. Love the work you put into it.
Gotta be Starman. Hell yes! Glad you did another M82 repair, they're fascinating. Also i think later 2600 cartridges did do that memory swap trick, like Pitfall 2 for example.
Dude, you're the best man. Legit an inspiration for me. Keep up the great work
This video explains the process a lot better than the last one, great video!
We know cartridges load, zelda had screen transitions too. The point is the loading is so minimal that it doesn't fit the colloquial definition associated with the term.
you are quickly becoming an expert on those units :)
"The adventures of Bayou Billy", just killed me! I remember it again and again, for weeks!
Next month, Ben makes his own one from a base NES and a custom PCB!
Never saw one of these before. Very cool. So, you could pick your favorites, install them, and just select through and play which ever one you want.
Ben heck... a master at work!!! Such a bloody legend
omfg! time lord! that was the game i had as a kid never knew wtf i was doing but i could never remember what it was called thank you!
So this is why Megaman (unlike ultrapen) have those big pauses. Never came to mind that only being able to write during the Vblank would cause those.
You know you have the right man to fix your console when they have a plastic box especially for their Non-Inverter Tranceiver spares.
I wish you taught a electronics basics class. This is pure gold even though I don’t understand a lot of it.
I was laughing when I saw that you were using an old camcorder for your screen to play. Then I realized it was basically perfect. It is a high quality LCD screen (Sony), that is build for the aspect ratio (480p) and is battery powered and nearly worthless to most so they are cheap to get. I love watching your videos for all the great ideas!
Ben, you should design an open source NES multi-cartridge system. That would be awesome! Do it better than the M82! You could even design it to fit under a NES so you don't have to recreate the NES hardware.
M
The M83
So Ben, have you worked on enough of these to build your own yet? Looks like you were having fuuuun. I bet you could come up with a more modern and efficient way to switch carts. I mean how awesome would it be to just have a wall with all the cards displayed, and still be able to play them. I bet people might even, pay, for something like that..
He'd probably use a more complex form of what he's using to map the mappers lol
Introducing the Nintendo M82 Portable!!
I really like your videos and very educational. I also find it very educational how to make a diagnosis. Thank you.
Ben: I still have my sword
Inner-monolouge: heh heh heh, "s" word
Ben: "S" words, I'll take "S" words for 800
I about had a heart attack when Ben didn't hold down on the wite cube in Mario before he went to fly in the clouds...
Wow Ben! Great video yet again!
Inb4 this becomes a Nintendo M82 Store Demo Unit fixing channel.
+1 for joyful noises. Great vid!
Good ole classics!! Keeping the nost alive
27:58. "The adventures of Bayoo Billy". HA-HA-HA-HA-HA!!! LOL!
I gotta say, man, that Memory parody at the end was masterful. You ever do your own rifftrax? I'm a sort of fairweather fan (been in and out since the Nintendo PlayStation prototype stuff) and have no idea, but your jokes have real MST3K energy.
This man is more than inspiring. If I could subscribe twice I'd do it.
So great to have Ben back!
I hit the subscribe button because of your song. Well played.
I would absolutely watch a video of Ben Heck doing a 3 lives Contra!
Agreed! Shatterhand sountrack is so good!
Amazing work
41:20 good Stallone impression here lol
When you said that A2 and A10 were the issue, my mind immediately jumped to old nightmares of bad µC drivers on a multiplexed adr bus (because they would be on the same physical pin),
Hey Ben, you could always DIY a mechanical keyboard with a calculator button. It's a fun project and the result is way nicer to type on. Stay safe!
Congratulations!
Great birthday present of an upload for me! :P I really need a scope at work (auto tech), every once and a while I need to compare waveforms on a couple sensors at once and it'd help a lot, rather than using min/max on the ol' Fluke 87V.
Anyways, I'm jealous of yours. :P
Yes Pro Wrestling all about Star Man! Great job on this refurb, you're great!
epic... Ben Heck gets to work on the coolest stuff!
Omg, I’m so behind the times. What happened to the Ben Heck show? New channel? I’m got so many videos to watch now. 😃
UPDATE: Ben did a great job with this thing especially correcting voultars mistakes the guy always evily quote tweeting people and putting them on blast on twitter when he charged this kid full after almost ruining it discusting! Well I’m happy to say this has been fixed the kid who owns it actually fixed it, turns out it needed some missing decoupling caps on some of the chips. So I guess know it all voultar couldn’t figure it out but a non ee did.
Thank you for providing the best way for me to assert that my brain is an actual 🥔 with this upload. It was in limbo with a few of my close friends (anime body pillows), but this helped them agree this determines my potato brain assertion is correct👍🏻
Voice of an angel.
Guessing on the cartridge bus side?
Plenty of visible lines connecting all the slots vertically. 😁
Said that, more videos like this one pretty please. 🙂
It was truly amazing what Nintendo and other game designers were able to do with only 1 meg of ram!!
Your next project should be to use a heatgun or reflow station and remove everything on one of these after taking really good pictures and then scan and measure the boards and traces and get replica boards made up and figure out all the chips to basically make a replica to test things on
Regarding Punch-Out: it used Character ROM, not RAM. What made its mapper (the MMC2) special was its ability to automatically swap CHR-ROM banks when the PPU read a certain tile from the pattern table. This allowed games to increase the number of unique tiles shown on screen without having to spend precious CPU cycles on using cycle-timed code to swap CHR-ROM banks.
You are a great teacher!
This guy is a mad genius!
Is that M82 "S.O.S"'ing for help through the multimeter......Great videos as always Ben
You deserve some love fam, thats why i stopped by ❤️😊
Ben is a legend and a treasure. Wish I could be this dudes apprentice, id be his bitch for years
95k subscribers? Ben deserves to be in the millions considering what he does! Hopefully someday that will be the case. Thank you for being a great guy Ben & the “regrettable acting” is still alive and kickin’ today. I enjoy it :) thanks again.
Lol
Learning so much. I deal with so much micro circuitry at work i really have never been taught troubleshooting at this level. although i am trying to dive in further. I am in Wisconsin as well BTW
Ben has gone mad with power he's repairing and modding consoles that barely existed.
@40:34 the absolute Legend with the Kevin from the Office quote. This is the real reason I watch Heck videos
A lot of the games with CHR-RAM are Disk System to cart conversions, as the disk only had one data stream so everything got loaded into PRG-RAM in the RAM adapter, then the graphics would be loaded into CHR-RAM.
Good job Ben!
You and John Carmack are my heroes
Your song actually made me subscribe.
That Cats rendition was quite good
"I might have to fight the zombie hordes to get them" lol
CATS except it's actually SpaceJam.
it's so fun to watch someone who knows this dying art form.
I would have liked to see the temperature after the added "heat-sinc". Great repair!
Batman and Snakes Revenge. I remember getting each for 14 bucks at Toys 'R' Us when I was a kid, not at the same time however.
I have a Mircosoft Wired 600 keyboard and it also had a calculator button, love it! :D
Hold on.... beating Contra without dying AND you're a tech repairing deity ... I can only believe one of those to be true sir
I'm just chilling at Cedar Rapids!
No stevemre1989 references on this tray...nice.
Dat Bayou Billy impression
11/10
I still have a physical copy of Time Lord! I love the music in that game!
Great job!
Mom always called that bass on level 4 bosses ass. Lol
that slight rotation of the video at 34:40 ... lol
That solder mask (or maybe foil ground plane after the fact?) on the bottom of the board is a superfund site.
Now I can't hear the Time Lord music without thinking of Pezz82.
Is that the channel I was thinking of? It was driving me nuts trying to remember who used it. I went through videos from some of my favorite channels and even played one of his recent videos but didn't hear it, so I moved on. Thanks for placing it for me.
I understood the word Nintendo. I'll watch Ben Heck fix anything.
31:27 comes back with 1 chip *(and someone elses blood on his shirt) O.o
10+ points for the singing
