Hi there!!! For SCI, each folder name corresponds to the original Tandy driver size. The drivers inside now have more bytes due to the appended code, check your original driver size and choose a folder. The patched drivers have the file extension named to the port they are patched to. I recommend keeping your original driver as is and copy the patched one to the game folder and just change the driver name on RESOURCE.CFG file. Enjoy!! Yours truly, CarlosTex!!
