	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.

	~~Note:~~		<blockquote>See [[AGI DiskFree Decryptor]] for decrypting AGI games on modern Windows. or use a modern AGI interpreter, like [[AGILE]]</blockquote>

	Never try to unprotect your original game disk. Sierra games on 5 1/4" diskettes are normally write protected, but 3 1/2 inch diskettes may not be. Make sure that the original is write protected before proceeding. While running this unprotection program, you will be asked to insert your original game disk. This is only required for reading the copy protected track. Nothing will be written to the original diskette, provided you follow the instructions below. When games use more than one diskette, only the first one is copy protected. The other(s) can be copied by DOS, whithout any processing.

	Version 2.00 of this software has been enhanced to be even simpler than before. An "express" unprotect option has been added, enabling you to unprotect all Sierra software installed on your hard disk in a matter of seconds. Normally, everything is menu-controlled, but a more flexible command-line option for DOS-experts is also provided.
