"MESS" war ein sub-project von MAME.

Around 5 years ago, they were separate projects.
MAME for the arcade games, MESS for the computers and consoles. But since then, MAME incorporated MESS. It is still called "MAME", although the acronym "Multiple Arcade Machine Emulator" has lost its meaning.

Regarding chess on game consoles, there's an interesting one not emulated yet:

It is similar to TASC Final Chess in the sense that the module has its own CPU that runs the chess program on a separate ROM. It looks like this extra ROM isn't dumped yet unfortunately.
