The same type of crash also happens 9 out of 10 times when I simply insert a
headphone plug to get the sound over headphone or PC speakers. Is that also
caused by a bad power supply? Anyway, I'm pretty used to it now but I will
try switching to another power supply (earthed and protected).

Yeah, I tried initializing that one already... Same result.

I also ran a few other commercial ROMs on both TS4 units we have here and
they all show the same glitch (-1,-1 displaced BG2 in bitmap mode 4).

Does anyone else who has a TS4 board see this? Depending on your backdrop
color you can see a line at the bottom of the screen and on the right side
of the screen in bitmap mode 4 (haven't tried to look at other bitmap modes
yet).

For now I'm assuming it's a TS4 bug which was solved in the retail versions
of the GBA.
