I still have 5 (C-64) with 1541 drives and FD-2000.
That Ultimate 1541-II flash cart looks good. Dunno if I should get one

Still have my HACK games that was use in a CAB.
ex: in MsPacman, it says originally hit "F1" for play, I change it using a HEX editor (forgot the name, I think it was Renegade, or was it Warp Speed) to say, Hit "Player one Button to Play".
I did some games, but then it got tiring and killing lots of time. I dunno/forgto how many I did.
I made a CAB out of DK cab and shove in the gutted C-64 and wired up the keyboard (hack it) to the controls. This was all done before MAME was even born.
