Only few cartridges for this nice Spanish cartridge-Pong system surfaced so far. We added pictures here (Please click on thumbs for larger view).

Unfortunately our Wipeout cart doesn´t have a box. Anyway the picture of the cart shows how tiny these cartridges are. They are same than the carts for the Videomaster Colour Cartridge System.
Please note, the cartridge boxes did not contain instructions - all instructions were included in the manual of the system! Looking at it´s content, only 5 games are mentioned:

Super Sport (The classic Pong Games)
Moto (Motorcycle / Moto-Cross)
Grand Prix (Car Races)
Wipeout (or Breakout)
Batalla De Tanques (Tank Battles)

We have added scans of the manual for the CX.336 system download: Palson CX-336 TV Game Cassette Manual here.
