Emulator life cycle

During its operation the emulator experiences the following events:

• OnLoad
• SaveSettings
• LoadROM
• Step
• Exit

OnLoad

The user starts the emulator.

After the application starts, the settings are loaded and a motherboard is created in BreaksCore, which is specified in the settings:

• CoreApi::CreateBoard

When created, the board itself adds all the necessary DebugInfo and MemLayout.

The simulation state is paused.

SaveSettings

If the current board was changed when saving, the motherboard instance is recreated, just like when you run the application:

• CoreApi::DestroyBoard
• CoreApi::CreateBoard

LoadROM

The user selects the .nes dump to run:

• CoreApi::EjectCartridge
• CoreApi::InsertCartridge

This does not recreate the board, but simulates pressing the RESET button on the console.

The simulation starts automatically.

Step

CoreApi::Step is called in a loop until the user exits the application or selects another .nes image.

Exit

The user terminates the application.

If the simulation was running, it stops.

CoreApi::DestroyBoard is called.
