Can someone with their N900 overclocked at around 700 mhz run R-type on Mame and let me know what fps it runs at?

The reason i ask is that R-type on mame4all on my GP2X Wiz o/c'd at 700mhz runs at 100% and R-type on my N900 at standard clock speed runs at 84% after a stuttering start. i was just wandering what performance it will run at o/c'd (i am thinking of o/c my n900 only slightly nothing too high)
