It was made for PGE so I doubt so.

It can also be used for SMBX38A in case you will save PNG sprites (there are supported both PNG and masked GIFs formats). Some calibrations will absence as there are captured from Vanilla-SMBX. Therefore you are able to create them yourself. Calibrations INI files are will be useless for SMBX-38A, but you can use standard calibrations and "Image calibration" to physically move frames on the sprite to fit original hardcoded hitboxes. The INI calibrations are useful partially for LunaLua (except of animations), and completely for PGE Engine that is uses complete set of settings.
