Function Documentation

◆ slot_iterate()

void slot_iterate	(	void(*	callback )(uint8_t slot, void *arg),
		void *	arg )

MSX For each slot, invoke the given callback with the given arguments.

Parameters

callback	a user defined callback function that takes `slot` and `arg`.
arg	argument to be passed to the `callback`.

◆ slot_bcmp()

int slot_bcmp	(	uint8_t	slot,
		const void *	addr,
		const void *	s,
		size_t	len )

MSX Compare the byte sequence to the one present at the given address in the given slot.

Parameters

slot	slot address of the one compared to.
addr	address of the one compared to.
s	pointer to the byte sequence.
len	length of the byte sequence.

Returns: 0 if two byte sequence is same (or len was 0), otherwise non-zero value.

◆ slot_is_read_only()

bool slot_is_read_only	(	uint8_t	slot,
		void *	addr )

MSX Tests whether a given memory address of the given slot is read-only.

This tests, in exact, whether a value read from the address is differ from the value written before.

In other words, if it returns false, it means that the memory address is RAM or a typical R/W register. However, if it returns true, it does not necessarily mean that the memory address is read-only, but could be a write-only register, for example.

Parameters

slot	slot address
addr	address

Returns: true if it seems not a RAM, false otherwise.

◆ slot_is_MAIN_ROM()

bool slot_is_MAIN_ROM ( uint8_t slot )

MSX Inspects if the slot is MAIN ROM.

Parameters

slot	a slot address.

Returns: true if the slot is MAIN ROM.

◆ slot_is_SUB_ROM()

bool slot_is_SUB_ROM ( uint8_t slot )

MSX Inspects if the slot is SUB ROM.

Parameters

slot	a slot address.

Returns: true if the slot is SUB ROM.

◆ slot_is_RAM()

bool slot_is_RAM ( uint8_t slot )

MSX Inspects if the slot is RAM.

Parameters

slot	a slot address.

Returns: true if the slot is RAM.

Note: Since page 3 of the default internal RAM is always selected, this test only tests if the specified slot is the same as the slot selected on page 3 (0xC000.0xFFFF). However, maybe there is extra RAM in other slots.

◆ slot_is_internal_OPLL()

bool slot_is_internal_OPLL ( uint8_t slot )

MSX Inspects if the slot is the internal MSX-MUSIC.

Parameters

slot	a slot address.

Returns: true if the slot is the internal MSX-MUSIC.

◆ slot_is_FMPAC()

bool slot_is_FMPAC ( uint8_t slot )

MSX Inspects if the slot is the FMPAC.

Parameters

slot	a slot address.

Returns: true if the slot is the FMPAC.

◆ slot_is_OPLL()

bool slot_is_OPLL ( uint8_t slot )

MSX Inspects if the slot is a MSX-MUSIC.

Parameters

slot	a slot address.

Returns: true if the slot is a MSX-MUSIC.

◆ slot_is_SCC()

bool slot_is_SCC ( uint8_t slot )

MSX Inspects if the slot is a Konami SCC/SCC+.

Parameters

slot	a slot address.

Returns: true if the slot is a Konami SCC/SCC+.

◆ slot_is_SCCPlus()

bool slot_is_SCCPlus ( uint8_t slot )

MSX Inspects if the slot is a Konami SCC+.

Parameters

slot	a slot address.

Returns: true if the slot is a Konami SCC+.

◆ slot_is_BDOS()

bool slot_is_BDOS ( uint8_t slot )

MSX Inspects if the slot is a BDOS/FDC.

Parameters

slot	a slot address.

Returns: true if the slot is a BDOS/FDC.

◆ slot_is_ROM_p1()

bool slot_is_ROM_p1 ( uint8_t slot )

MSX Inspects if the slot is a ROM starting at 0x4000.

Parameters

slot	a slot address.

Returns: true if the slot is a ROM starting at 0x4000.

Note: This test only tests if a ROM header exists at 0x4000 of the specified slot.

◆ slot_is_ROM_p2()

bool slot_is_ROM_p2 ( uint8_t slot )

MSX Inspects if the slot is a ROM starting at 0x8000.

Parameters

slot	a slot address.

Returns: true if the slot is a ROM starting at 0x8000.

Note: This test only tests if a ROM header exists at 0x8000 of the specified slot.

◆ slot_is_ROM()

bool slot_is_ROM ( uint8_t slot )

MSX Inspects if the slot is a ROM starting at 0x4000 or 0x8000.

Parameters

slot	a slot address.

Returns: true if the slot is a ROM starting at 0x4000 or 0x8000.

Note: This test only tests if a ROM header exists at 0x4000 or 0x8000 of the specified slot.
