fusion emulator crash/freeze

hi,can anyone help,i have a problem with FUSION emulator,i can run it perfectly at 60fps ,no sound problem,all run smoothly the only thing is that after 10/15min it always freeze during a session,can be a MD,MS or game gear i don't understand because the first evening i tried it i played for about 4hours and no problems but the day after hell arrived,any help would be great.In alternative can someone suggest another good sega emu?thanks PS.my pc have windows 7

Hmmm,that freeze never happened with me.Maybe your hard drive is faulty.You should use the chkdsk option and check that the hard drive doesn't have bad sectors and errors,if it does,use the /f option with chkdsk.GENS is a good sega emulator too.

any version of gens is quite good. Fusion is based on it. See if one of the gens versions freeze.
