Easy MAME4ALL PSP Question

[mlcurly16]

Ok, I can't figure this out:

Just downloaded MAME4ALL; I can get the roms to work, etc. but what my MAIN problem is, I can't figure out how to insert coins. How do you do this!?

its easy man..select for credit
about roms it's a trouble...you have to convert your rom zip with clrmamepro (a tool wich set you rom to the version your emu is)
you can extract the .dat file directly from the eboot

Ok, yeah, I figured that out at one point, but it didn't work.

At one point, I had a game loaded for about an half-an-hour, then my PSP went into standby, then it worked, but whenever I boot up a game now, it never works.

Most games don't work. :P

is there a vid or guide to using CLRMAMEPRO? i have looked all over and all i get is techno jargon... I read one part of a guide where you have to do something with the DATFILE. i have no clue .. wanna get the roms working on mame4all v4.9r... i only have 2 roms, and try to get some neogeo and old school games to work, but nothing. My other question is do i have to also recreate the neogeo bios for the those neogeo roms to work? any help or guideance would be awsome.
