Did i miss something? I can not find this template to download.

@PigsysRetroGameDevTutorials May i ask you a question? When using an emulator like gens or any other that has frameskip options... which option is more accurate regarding the "real" hw speed? Auto? 0? thanks.

I hope the Sega Saturn gets the tools and community like the genesis one day before I go lol

Great Video, very interesting content... What about SOTN, is it close to be completed? Will it be released till the end of 2024?

I tried making a shooter uusing another game engine but there were so few learning resources.. If I obtain the genesis tools does it have everything as far as understanding code things like targeting, AI, etc. I really think I can make it a Genesis game if all the resources are available. I realy emjoyed your video on space shooters, I have all my own sprite animations andspecial effects I just can't code.

so why are the bad guys dress like sailormoon in Kirito? hahaha

Is this an issue if I am using dynamic memory allocation? I am moving from one level state to another. But I only initiated the sprite engine once.... and the rest of the states I just reset the sprites...

What were tools that were used back in the day? are they lost to time? or is it that no one has really cared about making games on Saturn till now

Call me old fashioned but I I think that the Sonic Sprite looks way way better than the 3D polygon Sonic Sprite not saying it's bad work I think this is actually phenomenal that's just my opinion that's why it's better in my eyes

Is there a port of golden axe revenge of death adda

I did it today for my project. Thanks!

A new jewel tutorial.

Thanks, Pigsy.

mxretrodev mauro xavier is doing a rpg save sram based game

I can't stop thinking about how badly Sculptured Software did the backgrounds on Genesis MK3: Ultimate.

what sound driver did they use in batman and robin?

can we have the animated gears backgroud, at least?

Hi pigsy, are you gonna do mega cd videos at some point?

it could be useful if you teach developers how to implement save sram code function

Now I understand your response to my comment last week (you told me I should be watching that TPQ doesn't generate too many unique tiles). I completely forgot about VRAM limits. Thanks for taking on the topic in this video. I have a question for you: How would you manage the palettes to allow for palette swapping of sprites? For example, in beat'em up games, you have many enemies that are palette swaps. Given that you have only four palettes, and most likely two of them are being used for the backgrounds, you are left with two palettes for all sprites. Can you change the palette when a specific sprite is being drawn without altering the other elements on screen? Thank you very much for the video.

Nice demonstration, are you planning to show how to convert a video into 16-bit quality

I always wondered what the difference is between Pigsy's RAM and VRAM.

This doesn't seem like an actual hardware limit but a limitation of SGDK. That is, that games have the ability on the Genesis to draw tiles either as sprites, backgrounds, or foreground tiles. SGDK seems like a great tool for building platformers, but not limit pushers.

So, just to double check, you can basically freely allocate all of VRAM to background tiles or sprite tiles or any amount of a mix of both as you see fit, minus any space required for tile maps and such, yes? And the SGDK itself just defaults to the 1000 tiles allocated to backgrounds and 400 to sprites. Which is interesting that it does this and with those amounts, as it seems to be an arbitrary amount but is possibly based on what the tool creator(s) considered a pretty typical allocation of unique background tiles vs unique sprite tiles in the average game scene or something like that. Also interesting to note that the more of VRAM you allocate to background tiles the less you have for sprite tiles and visa versa on a kind of 1:1 basis basically, so it's always a bit of a balancing act in the typical game that tends to have both backgrounds and sprites of course, and you generally can't just allocate the entirety of VRAM memory to either backgrounds or sprites in most use cases. Nothing for free I guess.

Definitely a useful thing to know! I'm curious, would it be possible to set the number in SPR_initEx as a variable, and update it based on the needs of various scenes? Would it be possible to have a function to find how many background tiles are in a particular level, then update the SPR_initEx variable to change the sprite allocation as needed? I guess it could just be done manually, but it might be handy to automate it through code.

horizontal black bars wont help nothing but DMA

Thanks for the video, it's fantastic how you explain things. For this and the previous ones they deserve a subscription to the patreon.

Where can I get a manifold game cartridge for my genesis?

That's a great tool, but I have a suggestion for cases where the image has smooth gradients or more "natural" detail: run first the image through a floyd steinberg dithering palette reduction routine, reducing the colors to the minimum you think still gives a good result (e.g. 64 unique colors with no palette limitation), then run it again through palette quantization with no dithering. I think the result can be even better for some kind of pictures

you're a saint for bringing up volume adjustment btw

Good luck getting your hands on the dev kit from back in the day... I spent years looking and I've all but given up. I have notepad and an assembler, with enough patience and trial and error I managed to get stuff working so you dont need to go the SGDK route if you dont want to.

Thanks

litle flame skulls would be great

please make a 5MB ROM

Sonic 2, for example, displays 75 colors on screen in the Aquatic Ruin Zone. It does this using a mid-frame palette swap technique, which allows it to exceed the 64-color limit in the same frame.

comes to show that even with a limited color palette like that on the Genesis, you can still get some pretty as hell graphics, the crunchy colors in the images look so weirdly satisfying to see...!

please add some scenes to SOTN just like eanest evans

I'm having a great time doing a couple of videos at a time then playing with what I've learnt. Thanks

question: how do I use a tileset for displays?

for slower parallax scrolling, instead of writing int when writing a variable, write float, float is just like int, but for decimals

As @JohnnyApathy said below this creates a bug where if both characters are moving and one of the players presses B, then both do the attack animations. To fix it use if (value & (changed & state & BUTTON_B) && attack_timer == 0) // # player 1 - fixes bug and if (value2 & (changed & state & BUTTON_B) && attack_timer2 == 0) // # player 2 - fixes bug The full function is below which you can copy and paste // # this is my user created function for button pad controls for player 1 and 2 static void joyEvent(u16 joy, u16 changed, u16 state){ u16 value = JOY_readJoypad(JOY_1); // # need to put readjoypad in each function u16 value2 = JOY_readJoypad(JOY_2); if (value & (changed & state & BUTTON_B) && attack_timer == 0) // # player 1 - fixes bug { //if ((changed & state & BUTTON_B) && attack_timer == 0 ) // # This line above creates a bug for both characters so comment it out { SPR_setAnim(player, ANIM_UPPER); // # set animation to grand upper attack_timer +=1; } } if (value2 & (changed & state & BUTTON_B) && attack_timer2 == 0) // # player 2 - fixes bug { //if ((changed & state & BUTTON_B) && attack_timer2 == 0 ) // # This line above creates a bug for both characters so comment it out { SPR_setAnim(player2, 7); // # set animation to 8th row which is spin attack attack_timer2 +=1; } } }

I loaded first the background than the foreground into the main and the background appears like a mess. When I put the code like is in the video, first the foreground (BG_A) and then the background (BG_B) appears perfect. Is there any reason for that? It's how works the VDP? Do you always have to load first BG_A and then BG_B?

every time i try to compile and run it , this message pops up C:\Users\Admin>%GDK%\bin\make -f %GDK%\makefile.gen release && START /B C:\wgens211\gens.exe %CD%/out/rom.bin C:/SGDK/bin/mkdir.exe -p src/boot C:/SGDK/bin/mkdir.exe -p out C:/SGDK/bin/gcc.exe -m68000 -BC:/SGDK/bin -n -T C:/SGDK/md.ld -nostdlib out/sega.o @out/cmd_ C:/SGDK/lib/libmd.a C:/SGDK/lib/libgcc.a -o out/rom.out -Wl,--gc-sections -flto C:\Users\Admin\AppData\Local\Temp\ccmJpXMh.ltrans5.ltrans.o: In function `_reset_entry': <artificial>:(.text+0x734): undefined reference to `main' C:\Users\Admin\AppData\Local\Temp\ccmJpXMh.ltrans5.ltrans.o: In function `_start_entry': <artificial>:(.text+0x81e): undefined reference to `main' <artificial>:(.text+0x8f4): undefined reference to `main' make: *** [out/rom.out] Error 1

Thanks!

OPTPiX is what we used back in the day. It is the best converter to palleted tiles by far.

Skechers Megacraft finally makes its way to Mega Drive! It's what I've always wanted! this stuff is amazing, thumbs up to the people that make this happen

MP3 TO VGM CONVERTER. DIGITALIZED MEGA DRIVE MUISC SOTN SOUNDTRACK

Guys i do not want to ruin your dreams, but all of them are just slightly more than tech demos... I loved Sega Saturn at his time, and i saw awesome works for almost all Systems in homebrew... But i dont think the most of those demos could ever been completed...

I didn't know Tiled Palette Quantization existed! What an amazing tool! Thank you very much! I was trying to convert maps from arcade games by hand using GIMP and Krita, and it was a really long and complicated work. This tool gives you a workable image in seconds. As usual, an excellent and very informative video.

Hell yeah! Thanks for a tool that actually transforms pics into actual pixel art ;)
