I had a previous version of MameCE running on my E-115, and it ran pretty well from a performance standpoint, but was kind of quirky. I just removed it and installed the newest version, and using the same ROM's it's VERY slow, not even playable really. I tried Ms. PacMan, and it was so slow I cut and pasted the MameCE directory to the storage card to increase memory. With 17MB program memory free it ran faster, but still too slow to play. Checked all the options, which appear to increase speed at the expense of quality, which helped some. It's still slower than it was before, and not much fun. Am I doing something wrong? I plan on doing the 131 - 168 overclock, which I expect to help, but I'm wondering if it's supposed to run slower than previous versions, or if I need to do something different.

Also, it's been about a year since I downloaded any ROM's, and I'm still kind of new to this. When I go looking for them, are the ROMS between MAME and MAME CE interchangeable? Or are there specific ROMS for MAME CE? Any specific place I should be looking?

Thanks!
