My Treo 650 won't play Genesis

[totalnewbie]

Well I've checked the doc's and it say's that

"LJP basically runs everything fine on the Treo 650 without any tweaking or additional programs except for SNES. SNES will run for sure if you do a hard reset and use UDMH (having at least 8 MB of defragmented space in your internal memory). Freeclock will overclock the 650 from 312 MHz to about 416 MHz. The turbo multiplier must be set to 2 and the bus multiplier can be set to about 16 (if you hit apply and you can't exit freeclock, then you set it too high and will have to do a soft reset). This should net you around 30 FPS on Super Mario World."

My problem is it won't load any Genesis games at all, has an out of memory error, is there some kind of settings that need to be adjusted for a certain game to work, I had hoped to play Shining Force 2, and Phantasy Star The End Of The Millennium, I assume that I may need to use UDMH for it , but I don't know..

And I'm kind of afraid to use UDMH as I'm a total newbie, it doesn't wipe out the built in palm rom data or anything does it, because I don't know if I can restore that stuff..

I have 20mb of free memory, and a 2gb sd card..

Thanks , I was just worried that it might wipe out something then I wouldn't be able to restore it, I'll give it a try the next time I hot sync my Treo, and if it works well the price isn't that high either for the full version. I think I may need to run Cleanstart or something like that too.. To free up my memory..
