Another one: Please release a better tool to compile/decompile your own j2a files. I knows there's that Python tool, but:
1) Not everyone want to install software that may give an attacker an ability to execute custom code without even compiling it once they're in someone system or even before (via social engineering, like here's a receipt for something you didn't buy from a store you never heard of, but please open it anyway). All interpreters fall under it, even PowerShell.
2) Even if they have nothing against using python, they may not get a correct version of it, especially when 2.x line (which seems to be used by the tool) is concerned. There were several changes to the 2.x branch over the years before it became such a mess that they decided to rewrite half of the interpreter and call it 3.0. For example, if a script is written for 2.4, there's no guarantee it will work correctly on 2.6.
3) It simply isn't user-friendly. Some GUI-based editor would be easier. Perhaps you could take a hint from one of the various Doom WAD editors out there - they present the content in an easy file manager-style view that everyone can understand. Then it's all matter of just putting in sprites with the correct palette there and setting up the metadata.
