Doom Crafter

Have you ever wanted to play the original Doom games with your Minecraft skin? Well, wait no further as you can now do just so with Doom Crafter. This program supports the major java Minecraft features including trims and slim skins. However, only 64x64 png files are supported. Also please expect and report any bugs as this is still in early development. 

Note that to generate fists associated with the skins you will need the acc compiler and its dependencies either in PATH or in the local directory: https://zdoom.org/downloads
