10 ; Match offset: 8 bits (1 to 256)
11 ; Min length: 2
12 ; Total match bits: 16 bits
13 ;
14 ; Compress using:
15 ; lzss -b 16 -o 8 -m 1 input.rsap test.lz12
16 ;
17 ; Assemble this file with MADS assembler, the compressed song is expected in
18 ; the `test.lz16` file at assembly time.
19 ;
20 ; The plater needs 256 bytes of buffer for each pokey register stored, for a
21 ; full SAP file this is 2304 bytes.
