Yeah, from my past... 3 topics ... I need a language which can use debug registers without copying most of CE's code. (So, Delphi, I don't think so.) Is debug registers possible in C++? It's for a game with a CRC I am unable to bypass *cough*MapleStory*cough*, so I'd rather use debug registers. Pleasee help, or suggest a better language. Razz

Thanks,
Acim

Both require you to attach to the process as a debugger, so it is detected.

write a device driver and hook int1
Set the global debug flag, and emulate all reads and writes to it, and keep it up. (so also when task-switches happen etc, just disable the breakpoint in processes you don't want to break, but DO set the global debug bit)

that's how you set debug registers without that api. doesn't even require you to open the process
