I'd imagine to get a 16-bit game to load at 110 Baud he
probably started in 1991 and just played the first round in
time to sell it on eBay.

Seriously- that has to be a mistake. Nobody was still making
cassette games in 1991, and since every amiga has a 3.5" floppy there were never any made for it.
