adding mapper 30 support to existing emulator?

Post by wallmasterr » Sat May 16, 2020 9:23 am

How in-depth is it to add mapper 30 support to an existing emulator?
Is there a standard file that can be plugged into emulators or do they all deal with it differently?

It might be easier to just change the header or your rom (to "Mapper 2" with iNES Header Chercker for example) to make your rom working on emulator that doesn't support Mapper30 than opposite.

Ye thats what i have been doing , what features do we miss out on by doing this? everything seems good so far.
For context, this is for the Dreamcast emulator, for porting nes games.
I was gonna pay a programmer to do the mapper 30 stuff to future proof the project and allow other NESmaker devs to use it too.

Saving, but dont have that?
Animated tiles but kinda don't have that ether..

Mapper 30 functionalities like saving, animated tiles would not work with a Mapper 2 header. But in nesmaker, currently those functionalities are not implemented (yet).
Also, that fake header will work only for Emulators, not for making carts (in that case, you still needs mapper 30 boards)
