Changing the size of memory or changing the ROM version forces a reset of the PET.
The emulator has an IEEE-488 device at address 8. It can be used load and save (.prg) files.
Some programs don't run on ROM1 and some require more memory than the default 8K.
HMAN is a version of the word game Hangman without the gallows. I remember playing a Hangman game (in French!) with a PETSCII drawing of a little stick figure rendered piece by piece as the game progressed, so I feel like Fisher is taking the lazy way out here.
Even so, the display is clean, and the game plays well. The word list is challenging, with enough variety to encourage replay, and it's easy to add additional words to the program. Of course, because HMAN is written in BASIC, and there's no attempt to disguise the dictionary, you can always sneak a peek at the game's vocabulary to improve your guessing strategies.
