RGCD and Psytronik Software are incredibly honoured to present to you two of the finest arcade games available for the Commodore 64, Aleksi Eeben's acclaimed Greenrunner and Redrunner – both upgraded and optimised to run on both PAL and NTSC machines. Not only that, but Aleksi has also managed to squeeze into the 64kb cartridge version an updated (and also NTSC fixed) version of Retroskoi+, converting your C64 computer into a two-oscillator monophonic synthesizer.

To play the games (downloaded from the links above) you will need either a real C64 (and a method of transferring the files over to it) or an emulator. For emulator users, we recommend VICE, as it works on a variety of systems and is very user friendly. Just download the emulator and drag and drop the .prg file into the open program window.


Released back in 2006 at the Game Over(view) Freestyle Jam, Greenrunner literally blew the competition away with its frantic arcade gameplay and amazing mix of sampled speech and high quality soundtrack. It's a game so hardcore and visually intense that it's probable that even Jeff Minter would beg for mercy at the thought of having to beat all 100 levels.

Grab a friend (or take on the challenge solo), jump into your Cyanitizer and Yellowizer battle craft, buckle up and warm up the four-directional bug-blasting pesticide cannons. This is going to be one hell of a trip.

Playing Greenrunner

Greenrunner is a one or two player (co-operative) arcade style single-screen shoot 'em up. You control a small round battle craft that fires in four directions simultaneously and will have to face 100 waves of bug-infested mayhem to beat the game. It won't be easy.

Player one (Cyanitizer) uses the joystick connected to port 2, and player two (Yellowizer) uses port 1. Information on the various enemies, hazards, scoring and power-ups is helpfully provided on the title screen.


One year on, the bugs are back, and this time they are in full colour! Improving on the high-res character based graphics of the original, 2007's Redrunner challenges the player with an all new and improved 100 waves of chaos. Lock 'n' load!

Playing Redrunner

Conveniently, the game rules and controls are the same as in Greenrunner - and again the instructions are displayed on the title screen.


Retroskoi Plus is a 2-oscillator monophonic synth for Commodore 64. This enhanced Plus version exclusive to the RGCD Redrunner & Greenrunner cartridge comes with additional preset sounds and a wider keyboard range. In short, using Retroskoi+ and an audio connector you can rock up to a gig, plug in the C64 and cartridge and use your Commodore as a synthesizer or noise box - no monitor or other peripherals required!

Ordering The Official Cartridge/Tape/Disk

Greenrunner, Redrunner and Retroskoi+ have been updated since their initial release to ensure NTSC and PAL compatibility, and the game menu joystick control means that the two games are even playable on the Commodore 64 GS console. The cartridge version is available to buy from our shop. The cover art features an illustration by Miha Rinne and the game comes complete with a printed manual, Retroskoi+ reference sheet and a vinyl RGCD sticker. The 64KB PCB is housed in a clear cartridge shell illuminated by an internal flashing green and red LED.

The cartridge version is available in two packaging types, a standard card carton and a more expensive 'deluxe version' that comes in a plastic case (a Universal Game Case with a specially cut foam insert to hold the cartridge as shown below). The standard version is priced at £22, whereas the deluxe version costs £27. Shipping is £4 for UK/Europe and £5 for the rest of the world. A digital version of the game will also be sent out to all customers following receipt of payment.

The games are also available together on disk or tape from Psytronik Software - with the tape, disk and premium disk versions costing £4.99/£4.99/£9.99 respectively (plus postage).


  1. Hello there!

    The title music was made by 6R6 but it's actually a cover of one of my most famous chiptune "Unreal Superhero 3".

    I think it's written somewhere in the title screen :D

    1. Oh sorry Rez - I did know it was a cover via the comments at CSDB but until now I didn't realise it was your track! Thanks for setting the record straight :)
