Looks like one of the settings is causing a crash / corruption during the intro screen scene where Lapras is supposed to show up with the player and partner.

The following configuration file can be used to reproduce the issue. The seed doesn't seem to matter.
(GitHub doesn't let me upload it as a .json, change the file extension to that to be able to import it).

The issue is caused by a null pointer being returned by [EU]0x201C484 at [EU]0x201C3A4. This causes a crash on real hardware, whereas most emulators just accept it and load invalid data, which causes the corruption.

Looks like random overworld music is the cause of the issue, disabling it gets rid of the problem.
It also seems like this is the same problem as the one reported in #34.

Seems to be another timing issue, I guess then the issue is probably a special process waiting for a specific trigger in the music tracks? How annoying.
