I'm for sure no expert on this. But the bin files are basically dumps of the bankswitched ROMs.
Unless the source code for this game shows up, the only way to make this a disk-only game running from the 32K memory expansion would be to
disassemble the ROMs. Re-allign all branches and relocate code to high memory. Also you'd have to remove the bank-switching.

So basically you would have to disassemble the game and understand what part of code is doing what.
I'm not saying it's not possible but it is a big task. You'd write some kind of disassembler/scanner first.
Considering the amount of effort that would need to be invested, I guess you could as well rewrite the game from scratch.

Understood. Thank you.
