The resulting 32 bits are converted into a text registration code by adding the ASCII offset of $41 to each hex digit. However, the rest of the algorithm remained essentially unchanged. The second loop repeats that operation, only using the game's name instead of the license holder's name.īeginning with Mars Rising, later games added a step to these loops: XOR the current code with the common hex string $DEADBEEF. The first loop iterates over each letter of the capitalized licensee name, adding the ASCII representation of that letter with the number of copies and then rotating the resulting bits. Given a licensee name, number of copies, and game name, the code generator runs through two loops. All of their classic titles use the original algorithm by Andrew Welch. In their earliest days, ASW didn't require registration, but they eventually began locking core features away behind codes. Perhaps this case study on Ambrosia's registration algorithms will be useful to some. We may hope to see a few of their games revived in the future but at present, only the original releases are available. Now that Ambrosia is gone, new registrations are no longer possible, and due to their expiring codes, using legitimate license keys has become difficult. With signs that ASW's website was on shaky legs, members of the community made their own archives.ĮVula Escape Velocity Resources (Internet Archive backup of )ĮV Nova Storyline Walkthroughs (arpia.be)ĮV Nova Plugins ( ev.appcraft.name, Cythera Guides) (Third party backups of Ambrosia Software plug-in repository) (OS X (pre-10.15) executables/utilities)Įven though it was purchasable before then, the Ambrosia site had not automatically sent license codes for a long time, and people had to send e-mails to get one. Downloads for Nova, as well as Nova TCs, are available in the links below: Since circa May 2019, with going down for good it seems, there is no longer a way to legally purchase a license for EV Nova. Posts regarding EV, EV Override, and EV Nova total conversions are also welcome. Feel free to talk about anything related to the game EV Nova, the space adventure-strategy game created by Matt Burch and developed by ATMOS.
