I've been working on a port of "Out of this World" using source code I found online. So far, I've been able to port it to OS X successfully with a couple minor changes.
I managed to get it to compile under the PSPSDK, and made a kxploit'd eboot. However, when I launch the game, it seems to launch - accesses the memstick a couple of times, then returns to the PSP home screen. I checked stderr.txt etc but they were no warnings. Does anyone know how I could go about trapping errors better, etc? The game is written in SDL and C++, but I don't know any of PSP's native function calls.
I'm about 90% there with this port - I just need to remap the key assignments, and that's pretty much it.
