: That's possible and it would be unfortunate, but I'm not 100% certain of that yet.
In certain sections of the menu, the cut-off is 4 characters before over-write (E.g. the status/type field for each Digimon), and in other parts it's 16 letters (Names on the Trade Menu).
I would guess that means there's a data block of some kind per menu that defines what the cut off is for each attribute - if so, I could try raising those values and see if I can fit everything in. The original Japanese had a maximum Digimon name length of 10 characters, so I'm hoping it's less a hardware restriction than just hardcoding the maximum value possible.
...But currently, I'm having a hard time just getting a breakpoint to trip in Mednafen.
If anyone's familiar with it, here's my process:
Press Alt-D to open the debugger
Press Shift-R to open the Read Breakpoint entry
for the pointer
Press Alt-D again to get back to the game
Open the Map menu
In theory it should freeze gameplay when it reads the map name in, but I can't gotten it to stop yet.
