There is ~3k difference when comparing LGOP to ZORK. This difference is larger than the file size difference of the two "GAME1" files. The effort to update INF or create an 80-column SC version is more than I want to undertake and seeing how the F18A compatible interpreter was my goal anyway, I'll wrap that up in this thread.
Since the disk images you uploaded contain unique files named for each adventure, my plan is to update each disk by adding an F18A interpreter. This will allow the TIPI users to combine the files into one folder, if desired, and map it to DSK1. Re-assembling the interpreter would require me to find all of the VDP references for PABs and buffers, so I'm not going to try to increase the path.filename info beyond their current limits.
I have not decided what to do about the V9938 video register settings for VR0x8 to VR0xF. Maybe I should just remove the entries to avoid future compatibility issues. The V9938 folks can use the non-F18A version that is already on the disk.
