You can kill the WIP thread it's not a WIP anymore, it's a program annoucment. I thought I'd mention it here too because most people ask the question here, "how can I stop people messing with my media"? If you get to talk to TCG tell them "I WANT MY NVIDIA VOUCHER!"
I did a lot of testing I think it's solid as a rock and they wouldn't have given me a BSc Hons 1st if I was crap at programming. However this is the 1st release in the wild so, i dunno, people might find something CPU specific like little/big endian. For safty keep a copy of you files unencrypted
I gave up on moving strings and did everything with dwords instead so there shouldn't be any crashes worst that can happen is you mess up the encryption some how making your own ecryprtion routine. But with my functions hopefully that shouldn't happen as I've tested every character on a UK keyboard just fine.
