Install the mod then you know who
Anyway this is pretty easy, its not bypass obfuscated function it just using other method with different tools to know what value or func runs inside the offset
Theres several method u can use
1. Debug IDA breakpoint
2. Gameguardian
For game guardian, just search/refine the value like normally u do with GG then use the offset result(theres some additional things need to be done here, just some hint) on your mod. To save time to update every new version just use pattern search, i could mod this game ez but still too much hassle to update every new update. Not to mention the game quite fast ban, kinda waste of time to invest every update XD
I also just started learn this last year and already start revive some old game that using same obfuscate. Dont wait ppl to feed you knowledges in one place, go explore them
