No.22617 AJR Developer 11 days ago	I can reproduce segmentation faults on all machines listed except aplscar, which yields: MAME exception: i386: Called modrm_to_EA with modrm value C8!
No.22639 Firewave Senior Tester 10 days ago	Sets are flagged MNW so this report should be invalid.
No.22649 hap Developer 10 days ago	Not an invalid report, you can't hide a crash or MAME freeze behind a MNW flag.
