C3/F036 Decompress and Transfer to VRAM
Note that this subroutine uses a different Transfer Loop than the one below
C3/F036: A0FBF6 LDY #$F6FB ; Compressed Data Address C3/F039: A9C4 LDA #$C4 ; Compressed Data Bank C3/F03B: 2061DD JSR $DD61 ; LZ decompression to $7EC000 C3/F03E: A000C0 LDY #$C000 ; Transfer Loop to VRAM: Source Address C3/F041: 84E7 STY $E7 C3/F043: A97E LDA #$7E ; Source Bank (WRAM) C3/F045: 85E9 STA $E9 C3/F047: A0F00D LDY #$0DF0 ; Number of bytes to transfer C3/F04A: 84EB STY $EB C3/F04C: 64ED STZ $ED ; Add nothing to each value C3/F04E: 64EE STZ $EE ; Add nothing to each value C3/F050: A00060 LDY #$6000 ; VRAM Destination C3/F053: 4CB9DD JMP $DDB9 ; Transfer Loop to VRAM
