idea Real Challenge Mode (black 2 white 2)

[Johnbss]

Hi I am really bored by Pokemon games difficulties and since i have noone to play with online, i want to pump up the games challenge mode (whose existance actually gave me this idea), makeing alle the gyms and post game encounters and the elite 4 a much of a challenge as I can (becuase lets face it the actual challenge mode is only slightly more of a challenge)

So what i need are a few pointers to what tools to use and how to compile a proper patch, and how i might find the adresses of the trainers pokemon stats for the challenge mode key (because i would like to keep the on and off option to make it a bit more professional), doesnt need to be too indepht, im thankful for everything you can give me, so dont mind posting as few as you know, its still better than nothing.

Im sure many would like this, but even if not id apreciate the infos.

Thanks and greetings, john
