We sneak in you house and update it while you are asleep ,lol J/K Updating will be simple as downloading the next/updated version and replacing your current version.
Please use the bug report thread here: http://www.xpgamesaves.com/topic/78558-xpg-chameleon-bug-report/ It's on the list of "features to be investigated". I know it's possible from a technical point of view, but as you can imagine, there's other stuff to consider when implementing an option like that.
for the update code take a look at fsd's code you could maybe borrow some from there. other stuff being? hosting / whos gonna pay for it / etc? as i said on your farcry3 blood dragon trainer this is got to be the best trainer menu around. nice work good job
Don't worry about the code. The code for auto updating the engine is as good as done. (Which I didn't need to borrow from anybody, btw). I've been playing with this idea quite some time already and had created a proof of concept which works pretty well. It will need tuning if we'd ever want to release it, though. It's the infrastructure behind it indeed that requires thinking on how to implement. I'm pretty sure we could hook it up to the site without too much trouble. But there's so many things that need to be thought over and talked about. There are also other new features we're working on which are coming either in the next or up and coming releases. So keep tuned and watch this lizard grow. ;-)
