No.05875 Robbbert Senior Tester Mar 14, 2010, 03:06	I've noticed in 0.137, when it crashes, MAME simply outputs a line of dashes and returns to the prompt. No register dump or message. I'm using the build from the official download page, normal 32-bit, not optimised for anything. Running on XP 32-bit.
No.06161 Kale Developer May 22, 2010, 17:07	For whatever reason, ST-V bitmaps never had x/y boundaries checking, which made this to crash.
