Re: Make a wish / What if : Genesis

Re: Make a wish / What if : Genesis

In priority order : - 4 palettes for sprite + 4 palettes for BG. - RGB444 colors would have be neat too. - Z80 having priority on BUS. - 128 KB of VRAM just to make the VDP design more elegant (no weird hacked 8 bits VRAM access). - very simple logic to transform TILE <--> BITMAP (a la SegaCD) I thi...

Re: Horizontal interrupts to stretch image?

SGDK will cause an important overhead for sure as it uses an internal callback then call the "user" callback from it (use SYS_setHIntCallback method for that)... If you really need to have fast hint callback, just place code inside the _HINT method of sega.s file. If you cleverly optimize your H-int...

Re: SegaCon 1(2017): Chaos Emeralds Party

Re: sprintf issues

myself i'm using mix of strcpy(..), strcat(..) and intToStr(..), but it's a pain compared to sprintf(..)
