Herein lies an assortment of Tandy 1000 games patched to run in 16 colors—and sometimes 3 voice sound—on an IBM PCjr. Twenty-eight are based on patches that have been circulating around online for years (with a few alterations), while 21 are based on patches I figured out myself.

All of the games are patched to run in fast memory to provide the best performance on real hardware. They are also confirmed to run on a real PCjr with 640kb of memory using either DOS 5 and jrconfig.sys, or DOS 3.3 and pcjrmem.com. Most games run fine with both configurations, but some have glitches, or fail to start when using one or the other. I have noted these deficiencies in the appropriate readmes, which accompany each game.

The readme files also contain any necessary hints for running the games, such as what to enter for password screens (all the games are cracked) and any eccentricities (such as longer than normal wait times) that you may encounter. I have also included tips on best practices for playing the games--if I did not think the controls were obvious.

Note: these games are patched to run on real hardware. Most work fine in DOSBox, but a number of them do not, displaying the wrong colors, glitching graphics or simply failing to start. If you want to play these games via emulation, just play the Tandy 1000 versions. It's literally the same graphics and sound.

If there are any issues with running these games, let me know. I will try and help you if I can. Some of the games, such as Teenage Mutant Ninja Turtles and 007, are nearly unplayable on a normal 4.77 MHz PCjr, even in fast memory. I include them here because of their impressive graphics (at least in the case of Ninja Turtles) or in case someone with a sped up 8 MHz PCjr is interested in trying them (let me know your results). 

And for games requiring a sound patch for Tandy music on a jr, I've included sound3v. 

This collection is mainly for people who, like me, own an IBM PCjr, but do not have the Tandy 1000 hardware mod. If you know of any other similar patches for the PCjr, let me know. I intend to add to this collection in the future.
