I made Setup2 in QuickBasic to resemble the original Setup. I don't know if I put license text somewhere, but I usually make everything free software under the GPLv3... so if it doesn't have it and you need it, I can add the license text.
The original Setup is part of Stunts and it's not free software. Important thing to note: while Restunts consists primarily in source assembly code, it is not free software (or "open source"). Stunts and any derivative product are "abandonware". We expect that we'll never get a word from the copyright holders and if we do, they probably will be OK with us to continue to do what we do and maybe even we could pay to have a special permission, but in the best case scenario, it'd become freeware, not free software. Good reason to make a new engine!
