Try to load Mortal kombat or tekken. For some reason the simple fighting games work well for the emulator. Longer games like adventure type seem to crash. As far as any emulator out there , they all work on QVGA devices. The only other emulator that works really good is Smartgear but you have to pay $5 for it. You can download a demo on thier website though. Most developers stop working on big projects for windows mobile for 2 reasons, lack of donations or the announcement the windows phone7 will not accept cab files.
Since you cant put link to rom site go visit my site and get the Rom list in the WVGA games section.
