 I don't own a PSP, but I can reproduce the issue with the PPSSPP emulator
 and the regular 2.6.0 build for that platform.

 1. Download the game (the wiki says that it's freeware)
 2. Start it on a PSP or on a PSP emulator
 3. The game just hangs on a black screen and never starts (even if you
 wait 10 minutes).

 I have no idea how/if ScummVM can be run in debug mode on the PSP, but
 FWIW I have an old MIPS netbook where I see that the game also hangs on a
 black screen between 45 seconds and 1 minute. It looks like it could be
 related to BitmapRawDecoder::decodeFrame() being slow; for example looking
 art/clouds.bmp takes several seconds there. But I'm not sure the PSP
 problem is related to this, since the game ''never'' seems to load at all
 on the PSP.
