GIMP ROM image file plugin

Graphics Editors

Description:

A GIMP file plugin for reading/writing/converting ROM images and bin image (tile) files.

Supported file extensions:

  • .bin
  • .chr (nes 2bpp)
  • .nes (nes 2bpp)
  • .gb (gb 2bpp)

Supported image formats:

  • NES 1bpp
  • NES 2bpp
  • SNES/GB 2bpp
  • NGP 2bpp
  • GBA 4bpp
  • SNES 4bpp
  • GG/SMS/WSC 4bpp
  • MD 4bpp

Build available for:

  • Linux
  • Windows

This allows for a more convenient workflow when already using gimp, instead of having to use an additional utility to convert to and from formats such as PNG.

The plugin is open source, feedback and suggestions are welcome. Currently only compiled for Linux, but could be compiled for Windows.

Image size: ROMs and tile files that are not an even multiple of tile width will get padded with transparent pixels at the end of the image, and have any trailing data stored as gimp image metadata. The plugin will attempt to preserve original file size and integrity as much as possible. Setting transparent pixels (in tiles) at the end of the image to non-transparent will cause those tiles to get written to the file and therefore increase the file size. Be careful.
