It's not really worth the hassle, it's way too slow to even play.
If you still want to try it...
Make sure you put the files into "X:\PSP\GAME\vbapsp\" Exploited of course.
Rename your rom to "rom.gba" and put in thier too. (Folder without the %)
By the way, DONT hide corrupt icons!!
I think there is a rom size limit of 16MB.(Not sure if that is bit or byte) :confused:
If you need an exploit app, I use SeiPSP...<A HREF="http://insanepsp.com/download.php?view.146">Download Here</A>
