Macro Definition Documentation

SCE_CHKREG_PSP_MODEL_UNKNOWN_SERIES

#define SCE_CHKREG_PSP_MODEL_UNKNOWN_SERIES   0

The PSP model belongs to a PSP series which could not be identified.

SCE_CHKREG_PSP_MODEL_1000_SERIES

#define SCE_CHKREG_PSP_MODEL_1000_SERIES   1

The PSP model belongs to the PSP-1000 series.

SCE_CHKREG_PSP_MODEL_2000_SERIES

#define SCE_CHKREG_PSP_MODEL_2000_SERIES   2

The PSP model belongs to the PSP-2000 series.

SCE_CHKREG_PSP_MODEL_3000_SERIES

#define SCE_CHKREG_PSP_MODEL_3000_SERIES   3

The PSP model belongs to the PSP-3000 series.

SCE_CHKREG_PSP_MODEL_N1000_E1000_SERIES

#define SCE_CHKREG_PSP_MODEL_N1000_E1000_SERIES   5

The PSP model belongs to either the PSP-N1000 series or the PSP-E1000 series.

Function Documentation

sceChkregGetPsCode()

s32 sceChkregGetPsCode

(

ScePsCode *

pPsCode

)

Gets the PSP system's PS code.

Parameters

pPsCode

Pointer to a ScePsCode variable which is to receive the PS code.

Returns

0 on success, otherwise < 0.

sceChkregCheckRegion()

s32 sceChkregCheckRegion	(	u32	umdMediaType,
		u32	regionId
	)

Checks if the UMD with the given media type can be started for the specified region on the PSP system.

Parameters

umdMediaType	The type of the UMD medium to check for. Typically GAME, VIDEO or AUDIO.
regionId	The region to check for. One of the SCE_PSP_REGION_* values.

Returns

SCE_TRUE if the UMD with the given media type and the specified region can be played on the PSP system, SCE_FALSE otherwise.

< on error.

sceChkreg_driver_9C6E1D34()

s32 sceChkreg_driver_9C6E1D34	(	const u8 *	arg0,
		u8 *	pHash
	)

Unknown.

Parameters

arg0	Unknown. Could be a pointer to a PspHeader.
pHash	A hash value.

Returns

SCE_ERROR_OK on success.

< on error.

Remarks

Outside of the corresponding VSH_bridge wrapper API (sceVshBridge_81706DA7) no call to this API has been found yet. And the wrapping API also does not appear to be called anywhere. The wrapping API has been added in FW 2.00.

sceChkregGetPsFlags()

s32 sceChkregGetPsFlags	(	u8 *	pPsFlags,
		s32	index
	)

Gets the PSP system's Ps flags.

The Ps flags can be used to check for special hardware configurations like whether the QA flag is set. If, for example, the QA flag is set, this will enable a special menu point in the XMB called "Debug Settings" which can be used to change PSP system parameters (such as the available RAM (32MB/64MB), the WLAN coexistency max clock frequency or whether the Cross or Circle button acts as the [enter] button).

The Ps flags can only be successfully obtained on certain PSP systems (such as test/development hardware). On retail PSP systems, an error is returned.

Parameters

pPsFlags	Pointer to an u8 variable which is to receive the Ps flags.
index	Specify SCE_CHKREG_PS_FLAGS_INDEX_DEFAULT.

Returns

0 on success.

SCE_ERROR_INVALID_VALUE The PSP system is not allowed to obtain its Ps flags. This is typically the case for retail PSP systems.

< 0 on error.

sceChkregGetPspModel()

s32 sceChkregGetPspModel

(

void

)

Gets the PSP series this PSP model belongs to.

Returns

The PSP series on success, otherwise < 0.
