The world has changed
“The world has changed. I see it in the water. I feel it in the Earth. I smell it in the air. Much that once was is lost, For none now live who remember it.” I think we all see it. You come and there's not a lot activity on this forum. Sometimes a troll, sometimes a small question, but all in all, t...

Re: Programming Genesis in ASM?
Hello, and welcome to the scene.
I've written several thousands of lines of Genesis ASM.
I've always used snasm
You could find some useful links (and a great emulator too) here : http://techdocs.exodusemulator.com/Cons ... ment-tools

Re: Yet Another Tilemap and Super Scaler Demo
So many great new stuff!
It's nothing short of Amazing Vic.
I'm not sure the 32X had such a good year since ... 1994 ?!

Re: 32X VDP going crazy with my attempts to draw
True.
32X TECHNICAL BULLETIN #14 states :
32X TECHNICAL BULLETIN #14 states :
In the 32X VDP, the shift bit becomes invalid when the lower byte of the base address set in the line table is $FF.
Therefore, make sure the lower byte in the table is not $FF when using shift

DREQ_FIFO Register
Hello to all.
I've tried to play with the DREQ_FIFO Register.
On real hardware,
It IS write only on the Genny side,
if 68S is not set, then the 32X cannot see it. The read value is always 0.
Thought that could help.

Re: 32X VDP going crazy with my attempts to draw
Take a look at my research posts about drawing sprites. There are routines that draws 32x32 sprites in various ways. It may give you some ideas. But realistically chances are you’ll have to settle for a low framerate or draw just the important objects. The 32x doesn’t give you enough pixel throughp...

The 32x really has a lot to offer, 2D-wise.
Keep on the hard work

Re: 32x "security code" reverse engineered
So,I've done my homework, and indeed, I can write at 0x70!! Tested on Fusion and real (PAL) hardware. Unfortunately, it looks like it doesn't work on Gens. I can write 0x70, the KMod debug window tells me it has been modified, but when H_INT happens, it looks like it goes to 8802A2 no matter what. g...

Re: Experimenting with 32x sprite drawing and scaling techniques
These results are just insanely great.Multiple scaled 32x32 sprites ~150 sprites
I’ve been working on 32x 2D for a long time, and what you’ve achieved totally blows my mind!
Congratulations to you.
