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.
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
