Beautiful work; to think this time last week I was griping about how Rockstar would never add this feature, and how I would just need to get used to it.
You've helped a great deal at this point, so once I've used up your goodwill & patience, kindly say the word and I'll stop bugging you & try to find some youtube videos to point me in the right direction, but until that point...
I'm not sure if it's related to memory patching per se, but I'm getting flashbacks of using the debug feature on my N64's gameshark (fire a shot, check for changes, highlight differences, rinse & repeat); sometimes I wouldn't even know what I was trying to change, I was just exploring how certain values effected the game. I'd love to rediscover that feeling on PC.
I'm interested in picking away at some older games for practice, but can you suggest a basic toolkit? Is it just your flavor of IDE + whatever tool is needed for the game's archive (.pak, .dat, .etc)?
