I'm down for perhaps 2 DIY kit if you still make them.Sega Naomi Maple Adapters to Allow Use of Dreamcast Controllers and VMUs
There are two options:
Do It Yourself Kit: $15 plus shipping
---This includes just the pcb and the two connectors. You get the DC controller ports yourself from an old broken Dreamcast and solder it together.
Fully assembled adapter: $50 + shipping.
---These will be on a first come, first served basis since broken Dreamcasts don't magically fall out of my ass. You can get on the waiting list and I will sell them in order as I acquire dead Dreamcasts and harvest the ports. Contact me to order these.
I had them made in white and red because it is similar to the Naomi logo color scheme. These allow you to use Dreamcast controllers or the Dreamcast controller to play games that support the use of DC controllers. This is virtually a MUST if you want to play Typing of the Dead or Lupin 3: The Typing. You just plug the keyboards in and they work by default. The other games require the controller to be turned on in the game test mode.
This thread discusses some of the games that work with the DC controls and the extent of how they are used:
It's probably worth noting that if you buy two DIY kits you can probably turn your own profit by selling an assembled pcb since each Dreamcast harvests two DC controller ports.
