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.

Game Notes
A BRIGHT SHING STAR is a demo programmed and illustrated by Elder001. With this demo he introduced PECBM video mode: with PECBM you can get rid of several petscii limitation, enabling some real pixel art capabilities on this 45 years old beautiful machine.
Luckily enough I ended up to be the first man on earth to ever do some real pixel art on a Commodore PET 2001: I tried to exploit some limitations this new technique has. PECBM can’t draw the whole screen in hi res / per pixel mode, you are limited to the equivalent of a handful of characters. Mixing some petsciii and PECBM together I managed to render full screen images. I drew some petscii images, then I hand picked the characters I wanted to replace with pixel art and created a collapsed map containing only those special characters, like you would do in a spritesheet. I then wrote a document with an array of the correct offset values so that Elder001 could actually extend back the graphics in the right place as they were inten
