Typedefs
typedef uint32_t	bmemptr_t
	Type of an address of banked memory.

Functions
uint8_t	bmem_bank_of (bmemptr_t loc)
	Returns the segment number corresponding to the specified address of the banked memory.
uint8_t	bmem_get_bank (void) __naked
	Get the current segment number of banked memory at page 2 (0x8000..0xbfff).
void	bmem_set_bank (uint8_t bank) __naked
	Expose a 16KiB segment of banked memory at page 2 (0x8000..0xbfff).
uint8_t	bmem_get (bmemptr_t src)
	Read byte from banked memory.
uint16_t	bmem_get_u16 (bmemptr_t src)
	Read 16-bits value from banked memory.
void	bmem_read (bmemptr_t src, void *dst, uint16_t len)
	Read byte sequence from banked memory.
void	bmem_copy_to_vmem (bmemptr_t src, vmemptr_t dst, uint32_t len)
	Copy from banked memory to VRAM.
void	bmem_bload_s (bmemptr_t src)
	Load a BSAVE formatted binary in banked memory into VRAM.
void	bmem_bload (bmemptr_t src, void *buf, size_t buf_size)
	Load a BSAVE formatted binary in banked memory into RAM.
