Assembly code snippets

This is an overview of all sorts of assembly code snippets that were contributed by many people. On the previous website there was a snippet library where users could create an account and post code snippets. Because this library has hardly been active over the last years the current website does not have this functionality anymore. However, because the snippets may still be of use the complete list is available here for viewing.
