Hi all,
Some time ago someone posted on this forums a demo meant to be "a test for proper mid-scanline PPU write emulation", toggling D3 of $2001 and D4 of $2000 at different times.
Does anyone know anything about its timing? Any source code available? Any emu running it properly?
A photo of it running on the real thing was posted too. I still have a copy of it, in case someone needs it..
Thx.
