I would gladly go back to a patch only system as this would save us A LOT OF BANDWIDTH as patches are about 100-1000x smaller than an executable... the good old days
But as Joe Forster/STA already tells you that most of the current protections (SD/SD2/SR) use an encrypted EXE. To decrypte them you'll need a unwrapper. As these are just not available for every version of the protection, it is impossible to do this yourself! That is why there are Fixed EXE's and not just (smaller) patches. If you would create a patch, by comparing the original EXE and decrypted EXE then the patch will be bigger than the orginal EXE (as the files are just too different), so this is useless. Most likely you did not try this yourself
FBSA only makes patches for games which are protected with a CD-Check (these executables are usually NOT encrypted). If they have a patch for an encrypted EXE then they always tell you to get the decrypted EXE first.
