[[Image:Burning Rubber - cara A.jpg|right|thumb|250px|A GX4000 Burnin' Rubber cartridge for the + series]]
A cartridge system was introduced with the launch of the CPC+ [[Plus]] and GX4000 series. This enabled developers to distribute games via cartridges on the new Amstrad. The cartridges are protected with the [[ACID]] chip.
== Technical specs. EPROMs ==There are different versions of the cartridges which contain EPROMs of different sizes. To indicate the EPROM size to the CPC+, different combinations of links have to be shorted.
== Protection ==
The EPROMs aren't encrypted, making it very easy to dump their content, or to replace them by other EPROMs. However, all cartridges must contain an [[RAM7ACID]]chip, a French hardware developer, created a device to hack otherwise the [[RAM7 Cartridge Hacker|CPC Plus ]]/GX4000 refuses to work, meaning that unlicensed third-party developers couldn't produce cartridgeswithout buying the [[ACID]]hardware from Amstrad.

== Demonstration System ==
Amstrad released a Demonstration system for his retailer in order to show GX4000 games: the [[Amstrad CSD]](Cartridge Software Demonstrator).
It was a 464plus 464 [[Plus]] motherboard, with an extra "daughter board) " allowing the insertion of 12 games cartridges, plus an extra special cartridge acting as an OS.
