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.
Game Notes
I have slightly expanded Tim Howe's Tetris version from 2010. With version 1.5 you can now set the start level at the beginning.
There are 3 variants: tetris8k is intended for computers with only 8k. The game is the same, just a few texts and the home screen away.
The normal version is tetris, and dactetris uses a DAC converter on the user port. The latter can be activated in Vice under Settings -> "Cartridge IO Settings" -> "Enable User Port DAC". For this version you need 32k.
The game was created in C using CC65. Detlef had adapted the libraries so that it would run correctly on the 4000s. I adapt it to the different keyboards because the scan code is interpreted differently (depends on the type of keyboard or the built-in ROM).
