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.

Before I started programming in Assembly in October 2019, I was messing around with BASIC in the superb online PET emulator at https://www.masswerk.at/pet/.
As a project to get going I took the code from the C64 football management game World Soccer League (by Scott Gardner and Alan Clayton) and ported it to the PET, having to strip out about 9K of code and data to get it to fit.
You'll need to play on an emulator if you want to save your game using save states, as I don't believe I touched the save/load code so I can't imagine it will work.
