Hey mate, don't worry.

Sometimes is very difficult try to find any differences and sometimes a lot of protos or betas only are retails pre-production versions.

Don't become depressed, your work is important. You try to buy some stuff, find changes and shared with the people, that's important even if at the moment we don't find any remarkable beta content.

Johnny M. betas can be some great sfuff... who knows. You can try to compress the iso in volumens, in let's say 4 or 5 parts for example, then if some fail to upload you only have to reupload one part again.

If you can't, let me know to me or drx and we setup an FTP to upload it.

Thanks for the contribution!
