Try This It Helps me run englsih beta 2 of light platinum on my psp..
well....aint working on gpsp....too bad...i got white screen, and on that emulator i cant change to 128k....well i aint going to play it after all
""wow i found which is the problem.....Wesley modified the header of the rom, and the emulator dont recognize it as a ruby rom so it cant determine the save size and it uses the default of 64k....which results in a white screen.
Here is what i did, downloaded this tool GBA-Header tool v1.0
loaded pokemon light platinum already patched on a ruby 1.0 rom, selected COPY HEADER, and copied the header from the original Pokemon Ruby 1.0...
Then Download VBA Then On Option Emulator-Save type-Flash 128k Then Reset the VBA..You Will Able To Play It On VBA and GBSP
I hope it helps those who want it to play it on psp, or maybe on a mobile phone."
Thanx To PTSHADY..hope it help..
