Hi there!! This patch not only allows for Tandy sound on an ISA card on either port 1E0 or port 2C0h (or anything else is easier to patch now) it also has Adlib detection removed. It will try to play Tandy sound first, as the Tandy detection was also defeated. You can still force any other sound options: A for AdLib Gxxx for CMS/GameBlaster (xxx for i/o port ex: g210) TS for Tandy Sound (not needed now) I for PC Speaker R for Roland In addition i patched the Adlib routines, AT PC's should now have no speed issues with garbled Adlib sound, it was tested in my Pentium MMX downclocked to 100Mhz. It should be fine for any fast 386 or 486. Enjoy!! Yours truly, CarlosTex!!
