Sets IX (start of block to load) and DE (block length) for ROM LOAD routine.
First data block - all game data between EAA1 and ECA1
|
||||
BF33 | LD IX,$EAA0 | Start of data block | ||
BF37 | LD HL,$ECA1 | Address for end of block | ||
BF3A | LD DE,$EAA0 | Start of block, game data at EAA1 | ||
BF3D | SCF | Set carry flag... | ||
BF3E | CCF | ...and then toggle so it's cleared | ||
BF3F | SBC HL,DE | Calculate the number of bytes in the data block and put result in DE register pair | ||
BF41 | INC HL | Need to add 1 to include the last byte | ||
BF42 | EX DE,HL | |||
BF43 | LD A,$FF | Indicates a data block to load (rather than header) | ||
BF45 | SCF | Sets the carry flag, which tells the ROM routine to perform a LOAD | ||
BF46 | CALL $0556 | Call the LD-BYTES ROM subroutine to load saved game data | ||
BF49 | LD IX,($DAF5) | Start of data block | ||
BF4D | LD HL,($EB61) | Address for end of block | ||
BF50 | LD DE,($DAF5) | Start of block, game data at 6790 | ||
BF54 | SCF | Set carry flag | ||
BF55 | CCF | ...and then toggle it so it's cleared | ||
BF56 | SBC HL,DE | Calculate the number of bytes in the data block and put result in DE register pair | ||
BF58 | INC HL | Need to add 1 to include the last byte | ||
BF59 | EX DE,HL | |||
BF5A | LD A,$FF | Indicates a data block to load (rather than header) | ||
BF5C | SCF | Sets the carry flag, which tells the ROM routine to perform a LOAD | ||
BF5D | CALL $0556 | Call the LD-BYTES ROM subroutine to load saved game data |
