Amstrad GX 4000 Homebrew

The Amstrad GX 4000 was a very unsuccessful console from the late 80’s, early 90’s. It was very unpopular and was not in production for very long. It was based on the Zilog Z80 and used ROM cartridges for software.

Not a lot of software was produced for it and when it comes up for sale on sites like Ebay, the cartridges are generally £30+ if boxed.

The console came with a game called Burning Rubber which I have and then I purchased a copy of Operation Thunderbolt, one of my favourite arcade games from the 90’s

After some searching recently, I cam across a homebrew cartridge with all the games ever produced for the console on one homebrew cartridge. A bargain at about £35 and was quickly ordered from the European site.

Over the summer, I sorted my loft and garage and managed to locate my Amstrad GX 4000 and decided to test the new homebrew cartridge.

Burning Rubber worked out of the box. Operation Thunderbolt didn’t work initially but after a clean of the edge connector contacts works fine. Had some problems initially with the homebrew cartridge but this turned out to be an aftermarket multi-voltage PSU I was using with the console set to the wrong voltage. A quick change and everything seems to work fine. You use the bank of dip switches to select which game you want to load from the homebrew cartridge.
