When the bike stretches too much, Elma will crash eventually. It will report an internal error (error.txt). There's no fix for this. Internal error is kind of generalized error message that is given every time some error has occurred in elma. For example opening corrupted level or trying to save rec file when rec folder doesn't exist will cause internal errors.
Internet Relay Chat. In IRC there are several Elma related channels, like #across, #battle, and #ballelma. You can just talk there about elma or ask questions, but it isn't limited to that. More info at Wikipedia.
