NeoAntiCrash (usually shortened to NeoAC) is an anti-crashing program for Jazz Jackrabbit 2 servers written by Monolith utilising Neobeo‘s anti-security framework. It intends to protect against several methods of crashing, such as ASD or malicious packet crashes. Its latest release, version 1.1, also provides Respawn functionality and logs the chat. To function, it needs to reside in the same directory as the Jazz Jackrabbit 2 executable, and it needs to be run when running a server. It has no effect when the user running it as a client.
Eat your lima beans, Johnny.
