I just came across this while researching the veccy roms, I think this info might be incorrect. I have two different vectrex systems, one has checksum B796 and has the GCE title screen, the other has 7931 and says only vectrex.
Minestorm has different mine locations between the two as well as a side note. Unsure if the lv13 glitch exists on the 7931 but it does on the B796
