Just hope one thing about errorious song

[Yave-Yu]

Play some romhacks' song, such as Pokemon Sors, when click some song, it will freeze then forced close. I just hope it won't freeze, just ignore it so I can switch to other song, because I don't know which song are bad.

I will need to know more details on which game it is exactly, and which song ID.

Pokemon DarkViolet, Pokemon Sors, Pokemon Unbound…
These are Pokemon FireRed hack.

Sorry for this back and forth, but I need exact information. E.g. I have tested a DarkViolet version from 2014, which I still have on my harddrive. But that one works fine, so I need to know which version of the ROM hacks you used, which please write the song IDs. That's very important, because I am not familiar with those games.

@Yave-Yu also might helps to send link to romhacking.net page/IPS patch/MD5 so ipatix can test (not romfile)

(you can calculate MD5 with powershell: get-filehash -algorithm MD5 )

OK, Pokemon Unbound as example.
By default, agbplay just recognize 327 songs, which not cover all. By manually set song number such as 500, now more song could be listen, but…
0397 Just play a short while, then agbplay freezes.
0469, 0471, 0473, 0474, 0475… Just freeze instantly. These example is enough I think.

Pokemon Unbound apparently has filler song table entries, pointing to an address 0xAAAAAA. Those songs certainly won't work. Song number 0397 dereferences a null pointer.

While I won't be able to fix those particular songs, I can certainly improve on the error handling that agbplay doesn't get stuck.
