Spanish company Terraonion – the same team responsible for the excellent Super SD System 3 for the PC Engine – has lifted the lid on its next project in a special ‘Terraonion Direct’ broadcast. (Wonder where it got that idea from?)

The big news is the firm has created the world’s first Mega CD / Sega CD FPGA optical disc emulator, which means its new flash cart – the MegaSD – can run CD-ROM games on pretty much any Mega Drive / Genesis console, even without the actual Mega CD add-on attached.

Terraonion performed the same trick with its aforementioned Super SD System 3, which was capable of playing PC Engine CD-ROM games without the need to purchase expensive add-on drives.

Retailing for 250 Euros and shipping in August, this is pretty much the gold standard for Mega Drive flash carts. Given the fragile nature of original hardware these days, carts like this are going to be essential if you want to experience CD software on original hardware.

Here’s the press release:

Terraonion today announced the all new MegaSD cartridge for Sega Mega Drive and Genesis consoles. The MegaSD is an all-in-one FPGA cartridge that duplicates the Sega CD/ Mega-CD hardware and allows owners to play these games back from a microSD card.
