>>>>> Sonic UP <<<<< By: Alex Litzau For the TI-83+(SE)/TI-84+(SE) (TI-83+SE/84+/84+SE highly recommended for speed) This game works with Mirage OS.* >>>> Description <<<< At last! Sonic the Hedgehog for the TI-83+/84+ family. Speed through the built-in levels as you work your way upward. This is a very simplified version of Sonic the Hedgehog that still provides a worthy challenge at a decent speed on a TI-83+SE/84+/84+SE. Either Celtic III or Omnicalc is required to run this game, but Celtic III is recommended and included. Thanks to Madskillz and Raiser for the awesome Sonic sprites. >>>> Controls <<<< Press "2nd" to jump and the arrow keys to control Sonic. Because this is a basic program, pressing any more than one button at a time will not work. Press "Mode" during gameplay to quit. >>>> Celtic III and Omnicalc <<<< Either Celtic III or Omnicalc must be installed on your calculator in order to run Sonic UP. However, Celtic III has some advantages over Omnicalc: > Celtic III is noticeably faster (which is what you want in a Sonic the Hedgehog game!). > When you hold down a button, the button press is immediately repeated until you let go. This significantly improves responsiveness. > The program will not unarchive Pic9 when Celtic III is installed. > The included Pic9 must be on your calculator for this program to work. > This program deletes all variables that are used and restores all graph settings when you exit. *NOTE: The Celtic III user manual says "Avoid using MirageOS to run your BASIC program. There are saferam areas that conflict with this application ... Conflicts are bad, as they may result in instability and potential (or inevitable) crashes." I have tested this program with MirageOS and experienced no problems, but I thought you should be warned.
