Is it possible to switch between H32 and H40 mode midscreen and back again during vblank(right before active display)? No, it break the sync on TV's... (not on emulator, of course). However, the fallowing method works : - Put Hint (or whatever) on line 180 (the less line you display the more DMA po...

So, no way to add .s files (in a VERY simple way) to a Stef devkit project? I ask that because I'm pretty embarrassed about explaining the things to some peoples when the difficulty is just to add few sprites to the rom (storing tiles in C program, as unpadded unsigned char, is just silly to me) ^^ ...

Ha yeah, the fast 1bpp>4bpp thing... There is also something obscure where you enter the full palette (16colors, 9bpc)... It is just a misunderstand or there is a hardware fading/alpha possibility when writing to the "framebuffer" (so the hardware find the nearest good color in the palette to fake f...

That is very interesting. So, it cannot be said that any given Sega CD title could display 6 Megabits per level, it could really only display 2 Megabits per level/load? That's the idea... more over, the code itself can take a lot of space, so it reduce even more the gfx power. Do you think that an ...

3d software rendering on megacd
Hi :) I just wanted to introduce a little chat about that (as it has been asked in a general sega board)... Please serious talk here. Compared to megadrive software 3d rendering, the segacd have those advantages : - Rendering cpu (subcpu) 75% faster - True 4bpp framebuffer - Auto bmp2tiles conversio...

Well, SEGA CD uses the Genesis VDP as it is... So, nothing different. Well, half half.. The segacd have a rendering hardware... which render picture from RAM to RAM... This rendering hardware have several little stamping modes, one use a 2048*2048 map made of 32*32 (or 16*16, i don't remember) pixe...

Woot! :D I'm ultra fond of the L & R tracks :D Also, you say that the pcm samples can be up to 36Khz each... However, the drums (especially on the tracks like U & D) looks a bit "grainy", does it mean that they are lower framerate? Can you eventually have some of them in "hi quality" and some in "lo...

I read somewhere that some companies did very light software mp3 player... But they call "light" something that run on a 25mhz risc, probably... However, a 16Khz/8bit/mono have a 128Kbs bitrate (like a 128Kbs 44khz Stereo mp3 ^^), approx 10 hours of music per disc. It is possible to make a player th...

There was a guy here named Fdarkangel that ported a bunch of stuff to MD... One of the ported thing (and that was used for tavern rpg until some point) was an LZSS decompressor. It was pretty fast http://www.genny4ever.net/index.php?page=works (see MDSA benchmark) assuming that the data was compress...
