Summary	02044: All sets in cps1.c: video from a DV cam proves the refresh rate of CPS1 in MAME is wrong
Description	an arcade operator provided me a video from a DV cam which proves the refresh rate of CPS1 and CPS3 in MAME is wrong. in the video the black bar caused by VBI is flying up, so the rate must be less than NTSC's rate of 59.94fps. CPS1/2 should be 59.6333 but I can't prove it in a digital way. it seems that CPS3 FPS is slightly different from CPS1/2. the machines in the video are, from left to right: SF3, SF3(MAME bootleg, please ignore it), Last Blade2, SFZ3, SFZ2AJ, SF2CE
Steps To Reproduce

No.02042 Kold666 Developer Aug 11, 2008, 14:37	the bug was fixed for CPS1, maybe we must edit the bug description?
No.02043 Iaspis Tester Aug 11, 2008, 15:24	or maybe split the report into two, for each driver respectively..
No.02044 etabeta Developer Aug 11, 2008, 15:51	I was waiting for a comment from nicola, but I guess we can simply report as fixed the cps1 part...
No.02045 Fujix Administrator Aug 11, 2008, 15:56	I have split the report into 02110 for cps3 and set this as fixed.
