Final Requests for Help

Okay, I'm having a heck of a time with this. I've gotten it working on a vanilla rom, but on my final rom, I only have 9 bytes left in the A1 bank, instead of the 12 needed, and changing the JSR to a JSL in C2 is crashing the game for me. Any ideas? If I were to hazard a guess, it would be that bank switching is not possible in the middle of this routine.

I didn't see this until you'd already fixed it by freeing up some space in C1, but if you want that space back, make this the only change in C1:

Code:

org $C1710F
JSL check_command_long
NOP
NOP

Then somewhere in C2 freespace, add this:

Code:

check_command_long:
JSR check_command_c2
RTL
