Drag'n'Derp: a new cartridge for the Nintendo Gameboy

Work with the classic 1989 console with the modern ease of dragging and dropping! This USB cartridge lets you load and back up ROMs and save data, without installing any drivers or special software.

It's kitted out with high-tech non-volatile memory, too, so no battery is used to store your save data - meaning it has a virtually unlimited lifetime.

This cart is great to use with LSDj; the ease of backing up your music means you will never lose your work again!

Check out the features or go ahead and buy one.

It’s been a while since I last posted an update; things have changed - quite a lot. The absolutely tremendous big change is the arrival of a newborn in our household, which has rather shaken things up. In particular, my free time and energy have dropped rather close to zero.

The Drag’n’Derp has always been a labour of love: I handbuild them here in Sydney, including milling out the shells and a quite extensive set of tests. That’s why they tend to go in and out of stock: when life gets busy, I just don’t have the time.

I’d like to find a sustainable solution for keeping them available - without compromising on quality. That probably means putting a bunch of work into finding new suppliers, and developing more automated manufacturing processes; these are things that will take time.

At the moment, what spare energy I do have is being funnelled into one of my other projects, the Saturn Satisfier for the Sega Saturn (see video, Patreon). It’s been mostly finished for some years, and it’s now or never: I need to get it finished so people can actually used it.

When that’s out of the way I expect to come back to this. News will appear here and on my Twitter.

While I’m here, I’d like to thank everyone who has supported and enjoyed the Drag’n’Derp so far; and to thank you all for waiting so patiently.

No More Shells


My supplier for the cartridge shells, who has been with the project from the beginning, has decided to leave the retro hardware game. I’m very grateful for their support over the years; the carts would never have looked so good without them.

I’m now in the process of finding a new supplier, and getting a new batch of cart parts organised. This is going to take some time to sort out, but carts will definitely be available again. I’ll post here when I know more.

With many thanks to everyone who makes this project worthwhile,

Prof. Abrasive
