MSDEXP and Clamshell Case for Terraonion MegaSD

This is a follow-up on the Terraonion MegaSD Cartridge article from 2019. In the past two years, I managed to find an MSDEXP adapter and a clamshell case for my MegaSD cartridge.

MSDEXP

Thanks to Mobius Strip Tech, I was able to source an MSDEXP. I can now finally play Mega-CD 32X games with the MegaSD.

The housing from Retro Frog is a high-quality print with a matte look. Inside there are two connectors, some passive components and a lot of tracks:

Philips CD-i RC6 Remote Control Hack

A quick and dirty hack to save a broken Philips CD-i RC6 remote control with a Sega Mega Drive controller.

Most CD-i players come with or are compatible with the 22ER9055 CD-i Commander, an RC6 remote control with a pressure-sensitive thumbpad. There are three known versions of the CD-i Commander:

  • RV 7701 – standard remote for most CD-i Players.
  • RV 7704 – with additional stand-by button for CDI660 and 670.
  • RV 7706 – with additional controls for CDI740.

When buying a used remote control, your first action should be to check the battery compartment for obvious leaking damage and also take it apart to find hidden damage. You never know if there were accidents in the past and previous owners just cleaned out the battery compartment without looking further into it.

Terraonion MegaSD Cartridge

This has just arrived yesterday: The Terraonion MegaSD Cartridge. The makers are known for quality products like the NeoSD and the Super SD System 3. Their recent move of the office from Spain to Andorra has stirred some controversy and caused over-the-top reactions from some buyers. I didn’t experience any trouble and my cartridge arrived safely within a few days. This is what I got:

Power Base FM

The second cart from Canada is the Power Base FM, also known as Power Base Mini FM. It is an attempt to enable FM sound for selected Master System games on a Mega Drive without modifying the console. This cart is somewhat hard to obtain, it’s now sold out in all stores.

On the next pictures you can see why it is called “mini”: It is much smaller than the official Sega Power Base Converters. It fits in a regular Mega Drive cart, but you have to cut holes in the top for the connector and the front right for the Pause button. The JTAG connector isn’t necessary and was added just for fun. Sonic is still looking at you because there is no label available – the only one I’ve found is from Stone Age Gamer and kind of ugly.
