Famicom/NES / Re: Zudu Go ROM Fix
« on: July 15, 2020, 01:04:45 PM »
I've fixed the ROM. I changed the order of the registers (e.g. STA $2016 > STA $2015). The ROM works in the original NintendulatorNRS, EmuVT. All title screens and first levels are tested.

All changes are in Python 3 script: https://gist.github.com/infval/baf4261878d88f93c0b4f3ab1f977c66.
Drag'n'Drop zudugo.bin or run script via command prompt:

I fixed iNES.dll (NintendulatorNRS) for the Zudu Go. Put iNES.dll in NintendulatorNRS\Mappers. Other OneBus roms will be broken.
I substituted the registers based on the MAME code (default, Zudu Go): 2016 > 2015, 2017 > 2014, 2012 > 2013, 2013 > 2012, 2014 > 2017, 2015 > 2016. I don’t know if the correct mapper can fix this.

What I've done:
1. Downloaded the source code of NintendulatorNRS: http://masterdisk.byethost15.com/blog/libg/static.php?page=NintendulatorNRS.
2. Opened src/Hardware/h_OneBus.cpp and changed:

}3. Deleted the code (left empty functions) in src/Hardware/Sound/s_VRC7.cpp because emu2413.cpp was not found.
4. Added Winmm.lib to INES Project: Properties > Linker > Input > Additional Dependencies.
5. Compiled INES.
