v1.2

This version makes sprite editing super simple! Open your ROM and save the generated spritesheet, edit it and put your palette in the top left corner, and import it in. The palette will be automatically converted into a GBA compatible palette, and the rest of the image will be as well. This image is then split into the different frames of each animation and rearranged and written to the ROM.

Here's an example spritesheet that has been edited with a Nazo sprite (not made by me).
