Yep, the VDP1 is a 2D sprite drawer, it's afaik the most powerful system for that, it can draw *many* sprites, it doesn't have any limitation except the fill rate or VRAM space, it can apply many effect to them etc... when PSX design came out, SEGA modified it a bit to help for "3D" rendering (think...

So this is software transparency rendering, the cpu is used to render the transparent polygon (simple gouraud rendering in half resolution, the hard part is to take in account the 3D objects to clip the polygone on correct part) in a VDP2 BG layer then the VDP2 apply transparency on this BG layer. W...

I forgot about Sonic R. :P Do any other emulators do the transparency that SSF apparently does? Kinda off-topic too, anyone got any idea/tutorial on how to get CEP to work with SSF? No ideas about how saturn emulator does the VDP1 rendering. I worked a bit on SSE (a discontinued saturn emulator) so...

Are your pics from real hardware or an emulator ? The transparency seems to be done in hardware of course as it's applied directly on polygon but i can't see the nasty effect of pixels overdraws... edit : Just saw the video, finally i'm not sure anymore we have hardware transparency here, if you loo...

Re: How do I compile something here?
Be sure to have the sames files in your linux GCC setup than mine win32 GCC setup, don't forget the default libc.a file or stuff like that... I'd like to make something in Windows first because I think you prefer to use it, once you have written that tutorial. That done, we can try to go to linux I...

Re: How do I compile something here?
Hi, everyone. I'm new at gen dev and I'd like to make at least some "Hello world", "Hi, mom.." "Is there anybody out there?" I'm reading some docs for some time now. First of all I prefer to use linux, so I compile a gcc only for make m68k stuff (gcc-m68k-coff) and it took me some time... After tha...

Okay, here's a slight update to the demo - it's just the rom binary and the Z80 driver source as that was the only thing to change. I added a few NOPs to the loop to get it as close to 22050 Hz as I care to right now. musicdemo-2.7z EDIT: As to how close it is now - it was 9.5% fast, and now it's 0...
