My command line for every playback: alphamame.exe -norc -window -rompath d:\emulators\roms\mame -pb <inpname>
I made sure that I'm using the right MAME version for each Inp.
I tested all these Inps again:
LCF's angelkds: Works on the P4, desyncs right at the start on the Celery, he gets 10 points. It works with and without sound on the P4 and just to make sure I tried it with and without -nosound on the Celery.
SJK's darius: Works on the P4, plays back to 1997030 on the Celery.
BBH's zwackery: Plays back to 5880 on the P4, works on the Celery.
Luja's zwackery: Works on the P4, plays back to 560 on the Celery.
RAT's raident: Plays back to the claimed
194130 on the P4, plays back to
194050 on the Celery.
pacman's paradise: This works on both comps only when using -frameskip 11 -nothrottle. I didn't try other frameskip settings but this works each time.
RobbyS's pairs: Works on the P4, desyncs right at the start on the Celery.
Luja's pairs: Desyncs right at the start on the P4, works on the Celery. This is pretty strange because it was the other way around with Luja's zwackery which worked on the P4 but not on the Celery.
My own nbajamt3: Plays back fine on the P4 but desyncs right at the start on the Celery. My first shot goes in although it shouldn't.
Luja recorded a zwackery Inp with standard-MAME. It plays back to 78050 on the P4 and 900 on the Celery.
Luja's .63 zwackery plays back to 80610 on the P4 and to 1610 on the Celery.
Fuzzee's metlclsh: Works on the P4, doesn't on the Celery.
Manfredini-BR's mk: Works on the P4, doesn't on the Celery.
zlk's cloak: Works on the Celery, doesn't on the P4.
John Cunningham's snakepit: Works on the Celery, doesn't on the P4.
