I'm saying kind of because sokyugrt will still lock up unless you quickly start the game. Strange, I thought a hard reset was supposed to be the same as starting the game from the commandline. I couldn't see any obvious cause when I checked the diff between 0.131 and 0.132. I could of course narrow it down, but I don't have any of the old "u" diff files, nor are they anywhere online. Tafoid could you please temp upload all diffs (not just 0.131u3) to make it easier to investigate regressions?

Now the main problem is that shienryu (and the vertical chars in stvbios in general) doesn't display anything / goes out of sync but the gameplay is fine. This HW is VERY fussy about timings / irq timings and I'm really amazed to see that things were working before...
