Theodore is a Thomson MO/TO system emulator based on Daniel Coulom's DCTO8D/DCTO9P/DCMO5 emulators. Thomson MO/TO is a family of 8-bit home computers produced by French company Thomson SA between 1982 and 1989.

When the "Thomson model" core option is set to "Auto" (default value), the core tries to autodetect the Thomson model to emulate based on the name of the content file, and fallback to TO8 mode if it cannot.
The "Start" button of the controller can be used to start the game. The core will then make an "educated guess" to start the game (cf. Theodore's README file for more info about it).
The Theodore core has the following option(s) that can be tweaked from the core options menu. The default setting is bolded.
