Description:

NES Mapper Reader / Rom Fixer / Rom Splitter Programmed by: Shawn M. Crawford [sleepy] Last Update: February 19th, 2017 Latest Version: 2.0 Coded in C#, Requires .NET 3.5


This utility will:

  • read NES ROM info based on the iNES Header (mapper, mirroring, etc)
  • read NES ROM info based on the NES 2.0 Header
  • clean a rom header by blanking out bytes 7 - 15
  • remove the iNES header (to prep for burning to eprom)
  • output the relevant BIN as a non-headered ROM
  • output the relevant CHR/PRG bin files to burn with eprom burner for dev carts
  • output the relevant CHR/PRG bin files to burn with eprom burner for Vs. Unisystem

It’s best to use the auto split option unless you know the PRG and CHR are incorrect sizes, since this info is based on the iNES header.

Example: Dig Dug (J).nes Results after Prep: Remove 16 Bytes NES Header: Dig Dug (J).nes.bin (24576 bytes) CHR dump: Dig Dug (J).nes.chr.bin (8192 bytes) PRG dump: Dig Dug (J).nes.prg.bin (16384 bytes)

Requires .Net 3.5 Framework
