Help/Support The RareVision VHS apps timer is impossible to nullify!

regeh32923noomloc · March 18, 2025

Rarevision VHS Lite: Retro Cam (https://apps.apple.com/se/app...tro-cam/id1087259990?l=en-GB) has a decreasing timer of how long youre allowed to record that im trying to patch. I’ve tried removing the timer for now for a while, but I just can’t get the timer to stop going down.

Steps I’ve taken are:

Finding the timer address. However, it changes every time (dynamic?), and it resets back to 60 seconds after an app restart.
I’ve also found the function (?) by using IGDebugger (0x26330), but when I tried searching for it in IDA, it didn’t work. I’m stumped.

My goal is to either:

freeze the timer
nullify the timer (-1+1=0 decrease)
add like 20 years to it

Any help or advice? The solution needs to work across app restarts.

You sure this is the correct offset? Did you follow the iGDebugger tutorial?

Yeah I probably did it very wrong since this was my first time ever using both the debugger and IDA. But in the debugger I’ve found this information:

RarevisionVHS +156464 [0x26330]
Ive also found out that x2 or x20 is probably the ones decreasing since they are the only ones with a value of 1, while x8 is the total time left.

Based on my attempts it also appears that (in the dylib) only the row with ”brk” in it can actually handle a breakpoint placement. If i try on any other row it either freezes instantly (like everything. I can’t even exit the debugger), or it just crashes the app
