5 out of 5 starsThe MGBC is my favorite Game Boy to use. Bucket Mouse did an absolutely fantastic job designing it, and it's a great soldering project. I would highly recommend using his Lipo charge board and a LiPo battery with this, as (for me) it made the MGBC much more usable. I'd never had a good experience with the MGBC using Eneloop AAA batteries, they kept dying on me with little to no warning.

5 out of 5 starsOnce again pleased with these Mega Drive/Genesis cartridge boards. Very easy to work with. This time I went simple and made a physical cart of the Mega Drive version of Tetris!

5 out of 5 starsThese repro boards for Mega Drive/Genesis games are just wonderful! I went all out and created a physical cart of the Sonic 3 Complete ROM hack for my own enjoyment, complete with working save feature! Definitely would buy again!

I design my circuit boards in CAD software, and send the designs to the board manufacturer. They produce the circuit boards, and send them back to me.

Frequently asked questions
Why doesn't my game work?
There are MANY different reasons that your game might not work. Please read the full FAQ on my website, and the appropriate tutorial for the board you are using, as a first step to troubleshooting a board. Missing just one step, or one solder joint, can cause an entire game to not work.
Can you assemble the board for me?
No. The only items I sell assembled will be indicated as such.
Can I have the gerber files so I can order these boards myself?
I don’t provide gerber files for every project, but the ones I do have links to them in the description. I also provide many schematics and in-depth details of my boards on my website across various pages for you to use to design your own boards if you’d like.
I only ask that if you are going to use my documentation to produce your own boards in order to sell them, please try to understand how it all works before doing so, and don't blindly copy the information.
Can you lower shipping costs? They're too high.
No. I *do not* control shipping costs, they are set by the postal service. I understand international shipping is quite expensive, but lowering the cost will only make me lose money!
When will my item(s) ship?
Processing time is 7 business days - this is a deadline I will always meet, barring any unforeseen circumstances, such as sickness. This is not a job for me; this is only a hobby. I have many other life responsibilities that WILL take priority over this store. As such, I do not fill orders every single night, but I will at least once a week.
I fill shipments in the order I receive them. If for some reason you need your item sooner than the date Etsy shows as the estimated arrival date, message me and I may be able to ship sooner, but I make no guarantees.
