This has been updated to support optionally adding or removing the suffix on save, and now uses flags instead of chained arguments. This allows for working on night tilesets (which previously did not work) and generally a better method of saving.
Examples
Bash:
rmxp16to32 --mode sub --suffix _wip
This will look for files with the suffix _wip and save them without. e.g: interior1n_wip.png -> interior1n.png
This will save a copy of every normal file with the suffix @3x, at a 3x bilinear smoothed scale-up.
Compatibility
This has been made to retain backwards compatibility so the default mode is still 'add' with '_x' suffix. No surprises for anyone using the tool for a while!
