Game input holds PET matrix keys down until you physically release them, which is best for arcade games. Type input keeps the original short-tap queue for entering BASIC commands.
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.

Pet Tetris V1.3 by Tim Howe 15, March 2010.
This is probably the last game EVER to be written for the PET!
It is 30% assembly code and 70% C, and has been compiled with
cc65. Source code should be available via the cc65 website.
It requires a 40 column machine with BASIC 2 ROMS. Unfortunately
it does not run under BASIC 4 (4000 series). This may be something
that I can rectify in due course.
There are 3 versions available:
tetris - This is the standard version and will run on a 3016 or a 3032.
8ktetris - This is a cut down version that fit into a 3008.
dactetris - This 'mega' version has wave sound effects.
To hear them, you will need an 8-bit DAC connected to the USER port.
This version requires a 32k mackine (3032).
