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.
About Tetris v1.5 (all models)
Tetris v1.5 (all models) is a tetris game for the Commodore PET, released in 2010. The game was programmed by Tim Howe and published by Self Published. This version is available in English. You can play it directly in your browser using the Commodore PET emulator or download it for use on compatible hardware or emulators.
Game Notes
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).
