OK, now I really need to find sources and binaries to the games I wrote back in the 1980-1984 time period. This is incredibly cool.
By the way, there are pirated versions of my games in his emulator. Choose any of the Taxman1-Taxman5 entries.
The Sheila game is there too, just misspelled as “Shiela”, and Super Taxman 2 (just listed as Super_Taxman).
