Many PC games autodetect when they are in a Tandy 1000 system and if so, will automatically use the Tandy video and audio hardware instead of other PC video adapters or the PC Speaker. I believe that virtually all Tandy-supporting games check a BIOS type byte to determine that they are being run on a Tandy and not an IBM PC/XT/AT. If so, could someone write a simple TSR-style program that will intercept the read and return an IBM byte instead?
