okay, this is for for droid x2 users (possibly others) that have the psx4droid black screen return to rom select screen when trying to load a rom. after relentless tries with different file versions, bios', and what not i figured out my/the problem. For some reason psx4droid does not like Chainfire 3d! Yup, i had it installed when i first got the phone and forgot about it as i really didnt see a use for it. So i uninstalled the chainfire driver, rebooted, then uninstalled the chainfire app, rebooted again. Then uninstalled psx4droid, rebooted, reinstalled psx4droid and wouldnt you know, it worked flawlessly. Try it and enjoy!
