Game Patches Allowing Games to Run on an IBM PCjr.

Many, many PC games were released during the 1980s that supported the IBM PC, XT, Portable, AT, XT/286, Amstrad PC-1512 & 1640, Tandy 1000, 1200, 3000/4000, Compaq computers etc.  However, many of these games specifically lack PCjr. support.  Some games may work OK with a Tandy mod, but many do not work at all or only support 4-color CGA and PC speaker sound on the PCjr.  Many games were hacked back in the day to work on a PCjr., and these hacks were distributed in PCjr. Newsletters, on BBSes, and through disks.  Recently, I have been sent a CD-ROM with a great deal of PCjr. material on it.  The most interesting portion of the disk contains patches to run certain games on the PCjr. which otherwise do not run.  I have prepared a list of the patches included on the disk for major games with a description of what each does with the game :
