Understanding Sega serials 102 – Japanese Third-Party published games
SEGA published all the software for the pre-MegaDrive era in Japan.
For MegaDrive and next systems SEGA attributed a prefix code to each publisher for their games serial. This code start by T- and is followed by two or three digits.
After that there is the game unique identifier, which is two digits then the console code (digit or letter).

| MegaCD | 4 |
| Game Gear | 7 |
| 32X | A |
| MegaCD-32X | F |
| Saturn | G |
| Dreamcast | M |
| Pico | 0 |

Electronic Arts was authorized to build their own cartridges/boxes and thus have their own serials.
They all start by EM200 and they are followed by a two digits unique game identifier.
