The last major remaining obstacle to an easy cross-platform patcher was that after patching the APK needed to be signed using a Java-based JAR signer, requiring users to have 64-bit Java installed. Emulamer and I chatted about this and decided it seemed feasible to write a signer in C#, which he managed to do fairly quickly and let me use his code, and in turn I figured out how to speed up the signing by a lot and let him know how to improve the speed in his own patcher.
