MS-DOS

Tic-Tac-Toe for 80286 (and higher) based MS-DOS machines. Supports CGA, EGA, and even Tandy graphics (also text mode).

A CONFIG.SYS manager/selector tool I wrote for use on my NEC PC-9801 clone (Epson PC-486GR). Lets me choose CONFIG.SYS files and corresponding AUTOEXEC.BAT files for specific DOS programs that have special needs.

Made because NEC's PC-9801 version of DOS 6.2 appears to not support a boot menu in CONFIG.SYS like western MS-DOS version 6 does.

This is a music tracker for MS-DOS that uses the OPL-2 chips present in AdLib compatible cards to generate sound using FM synthesis.

It was mainly developed using Borland Pascal (with some assembler bits by Keywiz) in a 386dx with a Sound Blaster Pro card, and even though it wasn't 100% finished, it was functional enough to create 3 demo songs which are included in the package.
