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.
As of my knowledge cutoff in October 2023, there is no verifiable information available about a game titled *Npack* written by Glen Fisher and published by CodeWorks - Cursor for the Commodore PET. Glen Fisher and CodeWorks - Cursor are associated with developing and publishing games for the Commodore PET during the late 1970s and early 1980s, but *Npack* does not appear in any documented lists of their works or in historical archives of Commodore PET software.If *Npack* exists, it may be an obscure or lesser-known title that has not been widely documented or preserved. The Commodore PET community has extensive records of games and software from that era, but without specific references or evidence, it is not possible to confirm the existence or details of such a game. If you have additional context or documentation, it would be helpful for further research.For accurate information, consulting historical archives, such as those maintained by retro computing enthusiasts or databases like *Mobygames* or *Lemon64*, might provide more clarity. However, as of now, *Npack* remains unverified in the context of Glen Fisher and CodeWorks - Cursor's known works.
