sg-sprite

Sprite layout parser for MAGES. engine.

This app restores original sprites from .png and .lay files found in chara.mpk archives. Note that this parser doesn't work with mpk files directly, you need to unpack sprites beforehand. There's a good tool for this: https://github.com/rdavisau/sg-unpack

Compatible games are listed in the compatibility list below. This list will be updated as soon as I'll test (and maybe fix) the parser for other titles. If you find out that it works with non-listed games correctly, feel free to submit PR or issue. Or patches, if they're not. ¯\(ツ)/¯

You also can read format description here. It's based solely on reverse-engineering of s;g0 sprites and thus is rough and incomplete, but it should give approximate vision of the file structure.

Missing functionality

  • Doesn't draw overlays. They're not very common, in the s;g0 at least. I'm not sure how to output them: Drawing each overlay on all suitable sprite variants will dramatically increase the count of output pngs, so I've just decided to not implement it until I'll come up with better solution.

Compatibility list

  • Steins;Gate 0
  • Steins;Gate Steam Edition
  • Steins;Gate Linear Bounded Phenogram
  • Chaos;Child
