By this are you asking for a guide on how to manipulate cash, gas, tickets, and gold values?
That’d be awesome. I’ve tried before, but without any success.
Another memory editor that could be used for this (as GameGem doesn’t seem to work on 13.2.3/A12 and iGG bypasses often cause it not to work) is DLGMemor Injected. DLGMemor Injected has multiple upsides, such as letting you use it on top of the current/targeted application, meaning that you don’t have to switch apps to use it.
I do suppose that DLGMemor Injected could be used to mess with Roblox on iOS, but then again so could lua scripts.
(Note to self: look into extracting the contents of or decompiling Windows Roblox exploits, for possible porting to macOS and iOS)
