When is a Commodore produced cartridge not available to buy in the shops? When it's a demonstration cartridge. This item recently turned up on eBay, and I was expecting it to be a finance program from the label. Guess I was wildly wrong. Appears that way before Nintendo got in on the act, Commodore also produced a cartridge to show off their new machine's capabilities. If you want to try out the Sales cartridge for yourself, grab the dump crt file and load it in your favourite emulator. Meanwhile here are some screenshots from the program in question.
