Well seeing as how I don't have access to my own computer, I haven't been getting any opportunities to help you. I'm supposed to be getting parts for my pc on Sunday. Not much more I can do until then.
Ill try Flora sky right now see if it works thanks. Also If it doesn't can you somehow just send me your patched flora sky that works on Gpsp thanks ill tell you if it works or not. THANK YOU VERY MUCH!!!
Well it seems that there is some problem with Light Platinum itself. If you can get it to work on your computer with VBA or any other emulator, it should work on gpSP. Let me know if you make any progress on getting the ROM to work in the first place. The thread for that hack is almost 300 pages and I haven't the time at the moment to find a way to fix it. I'll get back to you next week though.
Flora Sky is recognized as Pokemon Emerald US. Therefore it should work without you having to change anything. If it doesn't then you should apply the patch to a new ROM. I tested it on my PSP and everything worked perfectly. Even saves through the game.
Pokemon Light Platinum is giving me trouble though. I patched Ruby and all it does is give me a white screen. It does this not only on the PSP emulator, but on the computer as well. So it is either the patch, the ROM, or the program I used to patch the ROM. I'll try patching with another program, but until I figure it out you should at least be able to play Flora Sky!
I can indeed help you! However I'm going to be busy this weekend. I haven't used my PSP in ages, but I could figure things out via my old tutorial. I'm pretty sure I already know what I need to do. I'll just have to ask you to wait on me. Sorry. I'll definitely solve the problem though.
