GBA: Fixed missing sprites in Guranbo's character name screen
...
The game sets the sprites to obj mode 3 (by mistake?), which is an unused "stereoscopic" mode for sprites. Mode 3 seems to behave like mode 0 when the global "stereoscopic" flag is not set (previously "green swap"), so the sprites are meant to display normally in this scenario (instead of being hidden like they were before)

Debugger: Fixed crashes when switching between games from different consoles (in AOT build)
...
Caused by what looks like slight differences between how AOT treats an empty array (vs JIT builds) when it marshals the array (AOT sends a null pointer, JIT sends a pointer to an empty array)
This was causing issues in both builds (AOT crashed immediately because of the null pointer, JIT read from out-of-bounds memory)

Debugger: Fixed issues with NES/SNES/PCE assemblers
...
-Labels defined within the assembler that were referred to before their definition did not work properly and ended up being assigned the wrong value (when the label's address wasn't a value between 0x100 and 0xFFFF) - this is fixed by running multiple passes until the resulting byte code stops changing.
-Fixed issues where e.g EOR $00, Y would be assembled as a 2-byte instruction, which is invalid.
