DOS Application & Game Executable Runtime

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.

rxdos sources from 7.20N through 7.24 that are hard to find, so I have them here for reference. I also found an archive that are labeled 7.25.
