@ -33,8 +33,8 @@ XTAL notes (differs per model):
- G7400: 5.911MHz + 8.867MHz
TODO:
- backgamm doesn't draw all the sprites, what causes it? It doesn't seem like
it's a 824x bug since it does properly write data in the partial screen updates
- backgamm doesn't draw all the chars/sprites, it does multiple screen updates
and writes to the ptr/color registers, but does not increment the Y regs
- 824x screen resolution is not strictly defined, height(243) is correct, but
horizontal overscan differs depending on monitor/tv? see syracuse for overscan
- 824x on the real console, overlapping characters on eachother will cause
@ -52,6 +52,10 @@ TODO:
- verify odyssey3 cpu/video clocks
- odyssey3 keyboard layout is not the same as g7400, but there is no software
to test the scancodes
- partial screen updates aren't shown when using MAME's debugger, this is caused
by a forced full screen update and a reset_partial_updates in emu/video.cpp.
For the same reason, collision detection also won't work properly when stepping
through the debugger
BTANB:
- a lot of PAL games have problems on NTSC (the other way around, not so much)
