This is a Deobfuscated version of NeptunJS/NeptuneJS/NJS - Specifically v2.5.5 as of 5th of August 2018
https://impragma.github.io/NeptunJS
This repo contains "rom.zip" and its a GBA rom copyright of Nintendo. It's in here strictly so people can see the zip folder structure required for this Emulator.
This deobfuscation isnt complete. While all of the code IS de-obfuscated and removed entirely from the need of the launchers aswell as integrity checks patched out It still has the Big String Array from "javascript-obfuscator" on GitHub. The MAIN script that will be referenced as njs.gge, has 8 total "Blocks". Blocks are code executed in its own "(function(){//block;}(params,...))();"
All blocks are patched out but might not necessarily be 100% deobfuscated yet. cores/dataload.gge is in fact 100% deobfuscated and patched.
