Compatibility: Minor Issues

Notes:

There's some flickering in the text boxes, and the textbox jumps to the middle of the screen while saving in checkpoints and savepoints.

Needs manual JIT patches to fix soft reset and increase performance, but there's a catch: This game doesn't have a standard GBA header; the whole Game Title and Game Code (TID) fields are empty, so we need to manually craft a header if we want to have MJP detection to work on this.

Game savetype is SRAM, but the rom has EEPROM strings to break some emulators saving process, including GBARunner3.

Here is a .bps Patch and the .json config file to fix the mentioned issues.

This doesn't change anything about the game savetype issue as a whole, but for clarification, the EEPROM strings aren't to break emulators.

The EEPROM strings exist because the game was originally designed for an 8K EEPROM and was SRAM patched with GBA Tool Advance by Limited Run Games (or rather retro-bit, the company LRG outsourced production to) to allow it to work on their FRAM cartridges without any changes to the code.

I bring this up mostly to clarify that the game does not go out of its way to break emulators, and thus aside from the bad header and SRAM issue, is unlikely to cause any other issues.

erm, which dump does this correspond to, it certainly doesn't apply onto the 16MB verified good dump.
