WARNING: To run this Tunnel clone you need to download Doors CSE 8.1 from http://www.cemetech.net/, which includes the xLIBC library required to run this game. This shell can also run every ASM program and will let you run or edit anything from archive. Once you installed Doors CSE 8.0 and HPTUNNEL.8xp using your favorite TI connectivity software, use Enter or 2nd to get past menus and up/down arrows to move the car. Bear with the choppy framerate (the game runs at about 4-5 FPS). It was originally designed for a 400 MHz calculator called the HP Prime, and even though this 84+CSE version uses an ASM lib to enhance TI-BASIC language, it's still not enough to get it close to HP PPL speed. Special thanks: -tr1p1ea for providing the xLIBC library -Kerm Martian for the Doors CSE 8.0 shell and integrating xLIBC and other libs in it.
