Option 1 runs with PC-Speaker. INDY3 EGA did not support gameblaster, support was added in the VGA version
Option 1 could be replaced by Tandy in the same menu, by calling the patched executable that bypasses hardware validation. Dosbox.conf just needs to set tandy=on and sbtype=none. This can be called from within the batch itself
Detail, but SoundBlaster options could be renamed to AdLib for precision. There is no real Sound Blaster support in either version
a "goto quit" is missing for the :CMS option
Anyway I'm attaching my fixed run.bat proposal, and the patched executable for tandy sound that needs to go in IndyCru\EGA
IndyCru\run.bat:
