The MEGA-CD Catalog Project is a complete catalog of Japanese MEGA-CD hardware and software featuring scans, screenshots and some small bits of commentary. It does not include (or are there plans to include) US or European releases. Originally inspired by the excellent PCEngine Catalog Project and the now defunct Sega Saturn Catalog Project of which I contributed to.

Currently the hardware section is not completed.
The MEGA-CD Backup RAM icon in the data field denotes that the game can save directly to the RAM cartridge.
