==<br /> Description ==

<blockquote>
Anders M Olsson's SUP (Sierra Unprotection Program) removes the [[CPC Disk Protection|CPC copy protection]] from most AGI games, as well as ''[[Thexder]]'' and ''[[3-D Helicopter Simulator]]'' so they can be played on modern PCs. It patches the SIERRA.COM in [[AGI|AGI games]] so that the [[keydisk]] prompt no longer appears, [[CPC.COM]] is no longer loaded and the buffer which would be filled by CPC.COM with the decryption key at run-time will be already filled at program start. Or in short: It just "cracks" SIERRA.COM. It has an "express" option that allows you to unprotect all Sierra AGI games installed on your hard drive in a matter of seconds.

<blockquote>* See [[AGI DiskFree Decryptor]] for decrypting AGI games on modern Windows.</blockquote>
</blockquote>

==<br /> Usage ==

<blockquote>
Copy this .exe into the folder of your protected game. Running the decryptor .exe alone will search for "sierra.com" (to find the key offset), and will create a decrypted AGI file called AGI.EXE (the file you will use to run your game). If your loader is named something other than "sierra.com", you just run the decryptor with that loader filename as the argument.
