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:
Now that I have an extra backup of my Mega-CD save files on the Sega CD Ultra Backup RAM cart, I can replace the battery of my old CD BackUp RAM Cart without worrying about data loss. It is possible to do an open-heart surgery to prevent the memory from being erased and replace the battery while the Mega-CD is turned on. I went for that procedure to avoid having to copy all files from one cart to another again.
The cart on the right-hand side is a new backup RAM cart for Mega-CD with 8189 blocks of memory. That’s four times as much memory as the original Sega Backup RAM Cart has available for storage (2045 blocks). I’ve bought a used Sega cart in 2003 and am glad that the battery is still good – it’s only a matter of time until it loses its charge and my save files.
