Thanks, some aspects quite interesting though not all was new, I just let some things open, because I planned to expand a bit more. However, I still don't understand why it runs that slow as sdl is rather fast and my cpu also is not one of the slowest. Is it a matter with perl or still with optimizing every little bit of code(since that can't be nessecary for this little efford I don't really think so)?
Your changes are good for programming issues, but in speed nothing has increased.
