bit 1 (2) of I/O $3c8 appears to control "something" and seems related to these crashes.Tetriskr doesn't seem to check the H-Blank/V-Blank at the usual location (I/O $3ba/$3da) so it's possible that's checked at this other location instead,on a different manner however...

The .inp is invalid on u2.

E:\mame>mame tetriskr -playback tetriskr.inp
Fatal error: Failed to open file for playback (src/emu/inptport.c:3954)

It doesn't seem to be tied into what level you're at, as the bug happened to me on level 2 of the second game I was on in one session.

Make an INP file for MAME 0.149u1 and it has no gfx problems up to level 7.
Seems to work now!

seems to have a more annoying problem with inputs getting read twice or ignored tho, maybe a CPU sync issue.

This seems fixed now, other than having annoying input lag but maybe it's just like that?

Was able to hit level 8 with no GFX corruption, but at that level the input lag gets really frustrating.

Marking Resolved.

'Fixed in Version' is 0.168 and not 0.176GIT

The game speed/input problem was fixed in MAME 0.168:
cga: treat as fixed sync monitor [Carl]. See

The corrupt graphic was fixed in 0.149u1 or before
