I'm using a clean Kingdom Hearts 368/2 Days rom (256mb) and firmware version 1.56 b3, but every time I load the rom it the cyclods always hangs at the loading screen. I leave it there 2-3 minutes, but nothing happens. So I turn it off. I also try a trimmed version( used Tokyo Rom Trimmer) but had same results. I tried loading with and without cheats. I also got the rom from two different sources so i don't think it's a bad dump. I also tried hex editing the rom. Would it be okay it I edit the trimmed version. Have anybody else experience this and if there's a solution to this problem. Greatly appreciated.
