With the help of Plain Boiled Water, the administrator of PSP development forum in PSPChina, I've cleared those 2 bugs in the ITA. The Exception will occur when using "mikmodlib" incorrectly. The correct method is: play the music after stopping and freeing the music. Now the game runs OK and exit without any exception.

In The Air (ITA). It is a shooting game. And on PSP, the screen is rotated 90degree. The original game is based on WinAPI on Windows platform, from wzysj[at]citiz[dot]net. And I rewrite the game to suit to PSP platform, make it working and add some sounds. I know the game is not a big one and it is written without GU(in sdk). Just writing VRAM buffer simply. The source is written in C style.

The game works OK on firmware 1.5, but I must say that there are 2 bugs: sound control and exit exception. These 2 bugs wouldn't influence PSP after exiting the game. I have tested it on my PSP for many times. The problem may be caused by the "huge switch" and playing sound.
