Tip: When determining a time limit, remember that players won't be as familiar with the level as you are. If you normally complete the level with the timer around 100, others might run out of time on their first try.
While the conversion is done correctly, I may remind you, Fermín, that just adding "!addr" to a few lines of code in order to make a resource SA-1 hybrid does not count towards adding you as a co-author. Your name in the readme or code comments stating you did the conversion should suffice. I kindly ask you to refrain adding yourself as a co-author unless your contribution is too grand to pass by.
