Once the content and core are loaded the start screen is displayed as
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.
