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 *Catch!* written or published by CodeWorks - Cursor, nor is there any documented evidence linking CodeWorks - Cursor to Commodore PET games. The Commodore PET was a popular early personal computer, and many developers created games for it, but *Catch!* does not appear in any known catalogs, archives, or historical records related to Commodore PET software.
If *Catch!* is a lesser-known or obscure title, it may not have been widely documented or preserved in gaming history. Without additional context or evidence, it is not possible to provide specific details about the game, its development, or its release. If you have more information or context, feel free to share, and I can assist further.
