I've just glanced at LOAD81 now.. pretty good job! thanks for sharing.. I noted your keyboard event handling (using SDL).. we have something very related to this in Lunatik (at the kernel level, of course) [1]. We've a kinda fun script that uses keyboard event handling to implement a "key locker" using Konami code [2].
