Jupiter Lander is a game from a Commodore cartidge dated 1981. It was so graphically appealing that was shown in most VIC20 advertisements, back in the day.
This is a trainer version (unlimited lives) and runs on a 32K expansion, so memory blocks 1,2,3 and 5 must be set on (I have explained how to do this on the VICE emulator in this post).

It is a .prg file, so you simply drag it onto the emulator’s window to play. Users of TheVIC20 and TheC64 physical emulators should be able to run it straight away from a USB pen drive.
Play with the keyboard, intructions are provided in the intro screen.
Have fun!
