Enumeration Type Documentation

◆ boot_device_type_t

enum boot_device_type_t

Boot device type enumeration.

Enumerator
BOOT_DEVICE_TYPE_ROM	Boot from ROM
BOOT_DEVICE_TYPE_64DD	Boot from 64DD

◆ boot_tv_type_t

enum boot_tv_type_t

TV type enumeration.

Enumerator
BOOT_TV_TYPE_PAL	PAL TV type
BOOT_TV_TYPE_NTSC	NTSC TV type
BOOT_TV_TYPE_MPAL	MPAL TV type

Function Documentation

◆ boot()

void boot ( boot_params_t * params )

Boot the system with the specified parameters.

Parameters

params Pointer to the boot parameters structure.

Prepare system hardware, load reboot code and IPL3, install cheats, and transfer control to the reboot routine using the provided boot parameters.

This performs CIC detection (and optionally populates the CIC seed), normalizes passthrough TV type, configures and resets CPU/SP/PI/VI/AI state, programs PI DOM timing from the boot device, copies the reboot routine into SP IMEM and IPL3 into SP DMEM, installs cheats, arranges boot-time registers, and jumps to the in-memory reboot entry. If control returns, the function loops indefinitely.
