No.02784 R. Belmont Developer Oct 12, 2008, 16:43	Only sws95/96/97 are affected. Needs verification on a PCB.

No.03882 Phil Bennett Developer Mar 4, 2009, 18:10	There's definitely some connection to this note in the source: // HACK! Many games data ROM routines redirect the vector from the sound command read to an RTS. // This needs more investigation. nebulray and vshoot do NOT do this. // Timers A2 and A3 are set up in "external input counter" mode, this may be related. speedrcr in namcofl.c is also affected (although finalapr is not).
