How to change or edit mapper for NES.? Coz some game have strange mapper and can't run on emulator so I want to know how to modify or fix it to normal mapper.
There are two solutions, and both of them require programming.
- Mapper hacking: Find a mapper similar in capability, change every mapper access to use the other mapper, and share the IPS.
- Download a Free emulator, write a driver for this mapper, and share the source code patch.
Don't forget option #3, check if it says DiskDude! in the header, and remove that with a hex editor.
