Compatibility: Unplayable

Notes: White screen after BIOS, no$GBA doesn't show hicode apparently. Manual JIt patches didn't help, this game is also reported as non-working in both DS/DSi GBARunner2 builds.

Patches tried: BGYJ00.json

This is a case of hicode. The code here image jumps to veneers image The jump is too far for the current cache-hicode branch.

It can be made to work if you set the protection region for iwram to be only 32kb and then change the prefetch abort handler to assume any aborted address below 0x05000000 is actually a rom address. An alternative would be to replace those jumps by the bx instruction they jump to.
