I have ported Cheat Engine’s ceserver to iOS using frida.
・Reading and writing memory
・Enumeration of symbols and modules
・MonoDataCollector(il2cpp: not for publication)
I was able to port most of the functions.
However, only the debugger could not be ported.
Dwarf and others implement a pseudo-debugger with Memory.protect and exception handler, but it is not complete.
This problem was solved by using lldb.
Because lldb remote debugging does not support iOS on windows.
I was able to manipulate the debugserver directly via the above protocol and successfully set up a hardware breakpoint.
At this time, Cheat Engine does not support arm64, so I plan to support software breakpoints as soon as it is supported.
If you are interested, I would be happy to use it.
