Charset Auto lets PET software switch normally. Graphics or Business forces the selected character ROM for compatibility/testing.
Changing RAM or ROM resets the PET. Some programs need ROM2/ROM4 or 16K/32K.
The sound slider controls the emulated PET VIA speaker. Modern browsers require a click before audio can start, so Start Game also enables audio.
The emulator has an IEEE-488 device at address 8 for loading/saving .prg files. D64 disk images can also be inspected for PRG files.

Game Notes
I did a bit of reading about the generation of 15 Puzzles and learned that half of all randomly-generated starting positions are impossible to solve. I also took a look at the BASIC listing for this program, and it appears that there is logic in place to prevent unsolvable puzzles from being generated (although I didn't trace through in any depth).
