Sorry to say that (snif snif) but the DMA ROM>VRAM doesn't appear to be so fast... Only 192 tiles during a VBLANK (in PAL, 240 in NTSC).

VRAM access seems quite slow, even DMA (and even slower during VBUSY)... (thx Steve & Stef for the info).

However, 192*32 = 6KB... And i'm not sure that 68K can ...

Hi,


I just wanted to know if it was possible to use the 32x VDP without going (or having) the crappy genesis re-mapping...

PowerOn 32X > INIT/VDP > Shutdown 32x (but keep VDP output) > Run genesis game.

I think they did re-mapping to avoid interrupts timing problems on 68K if the SH is reading ...

Ok, i edited my message with your updates.

About the 4bits left in VRAM... Steve told me that the VDP was préparing something (like a preliminary Y sorting) few ms before outputing pixels to TV. I'm pretty sure it is working using those 4bits, any idea?

Well, you can be proud of your logo
In fact, its very difficult to do such kind of logo for development... 0X is a really nice concept

Pascal have spoutnik.... rahh, i need to hurry to make mine

:D Haha, some advertisement to say that Megacart is completed, ready for shipping... Just a few days to wait :)

For those who don't know about it, this cartridge have the fallowing features ...

Hi,
The genesis vdp have nice features around sprites...

:arrow: First i want to write down the well-known-things (correct me if there is an error):

Here are the limits in 320px mode:
-32 sprites per line max
-320 pixels of sprites per line max (10 sprites of 32pixels width, for exemple)
-80 ...

I confirm... pascal tool is enough powerfull to generate maps from a large bmp :)
Well, i'm using it along kaneda's bmp2tiles basic map functions...

There is also the powerfull tavern rpg map editor... which supports 3 layers (A,B,Objects) and 16*16px blocks... Of course, its customized for tavern ...

I want, I want, please PM me

The segacd part is indeed a very complex task, i really want to see how you handled it

Also, did you fix the segacd register listing bug? (the adresses were reversed from 0xFF to 0x0 instead of 0x0 to 0xFF).
