That opcode means it jumped to invalid memory, for some reason. On one of those I checked and it jumps past the end of the ROM file, so...not much that can be done there. Dunno about the other one.

Hello endrift,
I tried to play the game on Mednafen and mGba without success however I confirm that the no-intro prototype of Diddy Kong Pilot runs on VBA-M (sourceforge), apparently only VisualBoyAdvance is able to handle this prototype game.

Does it run if you try to run it on a real GBA?

Can't test but the game was dumped from a working cartridge I guess.

The dumps are weird because they have different behavior depending if out of bounds addresses are open cartridge bus or read zeros. I did fix this at one point.
