Guys Please Send Me Pokemon ROM Hacking Android Tools
Sorry dude, but there's literally one single tool for Android leaving patchers aside.
Wasn't there a map editor that worked for Android? Or did I make that up? I thought I remember someone mentioning it a while back.
ROM Hacking on Android is far beyond impossible and will probably never happen even in the future. Even if they do exist, you ought to search for them yourself. But as of now, ROM Hacking on mobile devices won't ever be a thing.
