Frequently Asked Question

Q: Is the adapter still available?

A: YES. When I run out of stock I'll update this page!

Q: Are all games compatible?

A: No, a few games are not compatible due to the way they were programmed (NB: it is often possible to patch the games if you are playing from a flash/custom cartridge). Please refer to the official forum thread to get an idea of games that may not be functioning.

Q: Does the Master Everdrive cartridge works with it on a Japanese Master System?

A: Yes.

Q: What are the difference between the "diagonal" and the "straight" adapter?

A: The diagonal version fits nicely into a fully closed system. To plug it you have to cut the bit of plastic on the back of the system that is preventing access to the extension port. The straight version of the adapter is for the few maniac people who don't want to cut that bit of plastic, the drawback is that you have to open your Master System case and keep it open to use the adapter. 90% of my stock are of the Diagonal version and this is what most people want.

Q: What is the estimated delivery time?

A: I am shipping adapters rather infrequently, please allow ~4 weeks for dispatch. Often I can ship faster (please query if you need one fast). If you don't receive your adapter after a few weeks please e-mail me just in case I forgot (it happened one or twice in the past!).
