Re: JPG decoding on SMD?

Just wondering, if anyone had tried to make JPG decoder for SMD? It probably can be useful for that type of games which shows picture for every level or couple of levels. I know that there is at least two different JPG decoders for russian ZX Spectrum clones, both written in the beginning of the 20...

(old) article you should read about making a 2D fighting game I remembered I also started to learn FSM...(they talk about it on the article) and prototyping in Director (Flash ancestor) ! Poking around the web, I see they actually have beta versions of SF Turbo for the Genesis. Then, apparently the...

My point was that, SF3 was not that much of a difference than SF2 as far as graphics so I think you could do a decent job of it for the Genesis. SF4 is a different story... Having some friends who live and breathe SF, graphics is not always their big concern, it's playability and matchups between th...

The fonz has made some tries with huge sprites decompressing. See his site. Yeah, that's why I tried at first my Mega Multi Fighter (an old demo is on the Demo part of this forum). I'm still working on it, I've solve a lot of bugs and now I'm working on the input part (to have combo and special). B...

The GNU assembler will allow you to use a ".bss" command So you could do something like this: .bss ships ds.w 1 players ds.w 1 .text blah.... .bss score ds.l 1 .text blah... And it will resolve the addresses for you when you link. The GNU assembler is not friendly on syntax as some assemblers so hop...

Make sure you restore the stack after your call to _puts, you'll eventually crash... movem.l a0, -(sp) bsr _puts movem.l (sp)+,a0 Also, I'm assuming the $1, $2 labels are defined?!? $1 move.b (a6)+,d0 cmp.b #0,d0 beq $2 jmp $1 (can use a 'bra' here also) $2 You can also do this $1 move.b (a6)+,d0 bn...

I got it to build a binary file, and was able to change a few things, including removing the Sega startup logo.
Nice! Any chance of posting it or making a group project?

Not sure if I can use plane W in mode4, though.

Just thought of another way do it.

Use another plane or sprite to hide the "Sega" text and scroll (right) with Sonic to reveal the letters one pixel at a time. This would minimize the number tiles you need and all is needed is to make Sonic a sprite.

Actually, it's just like I said, your over-thinking the intro. Each letter is probably 5-6 different images. You make tiles out of each state letter is drawn and change the letter with a different image while Sonic passes. You can even just do it via all tiles (include Sonic as an image) I would do ...

For the "Sega" background, you can just take a screen dump of the GG version and convert it to graphic tiles and easily display them back on the Genny. Pretty much the same thing for the Sonic sprite. If there is any music or the famous "Sega" voice, probably samples out there that you can use to pl...
