Disable MDV in JS rom

Post by XorA »

Hi, for testing it would be really useful if I could have a simple patch to remove MDV IO from the JS rom. So it never tries to read the mdv drives.

Something like a simple RTS injected in the right place. Does anyone know of a simple way to do this?

Would it be sufficient to just rename MDV device name to something obscure ? (name in linkage at JS ROM offset 4695, $1257)

BINGO! You win one free bit from the MD of your choice :-D

I changed that to XXX and now I can test other parts of the emulator!
