Sun Solaris 2.7 problems

Cinek — Thu, 23 Nov 2000 18:02:53 -0000

I don't know if it is a bug, but I can't get
X(Shm)PutImage to work in my 8 Bit resolution
environment (BadMatch error). Why ?
I really don't know...
On Solaris 2.6 everything worked perfect.

GB-joypad polling buggy in some games

Cinek — Wed, 22 Nov 2000 13:32:02 -0000

Some games, I suspect the SGB games,
cause the emulator respond wrong
in joypad polling routines.

1) SF II
It seems to be wrong because of the
SGB-packet commands (?)

2) Double Dragon II
This is a bad bug. I suppose the timings
of the CPU-ticks cause this problem.

Incompatibilities with GDK found

Cinek — Tue, 21 Nov 2000 14:42:23 -0000

In my opinion GDK uses the register lcd-control
(LCDC) in a strange way.
Well, but I have to admit, too, that I have some
timing problems with the CPU.
The problem is: I don't know the exact "tick-counts"
for each opcode in certain situations.
I figured out that the register LCDC is handled not
correctly in my emulator, but implemented in the
way it is, it plays more games than when I would
fix it for GDK.
This is a difficult situation and I have to learn
more about this bug first.
