Yeah it works fine on my 1.5 no problem. I copied the folders as per the Readme and it started up no problem, straight off the memory card, even though I have had issues running other emulators on my PSP.
I thought that the fire button wasn't working for a start but you just cannot see the bullets. I don't know if you could originally. It may be beacase the resolution or something (im no expert) isn't correct in the same way that you cannot read the text easily as you stated and so they are too small to show up.
Anyway I hope this is of some help and good job so far, Im off to blast some more asteroids!
