Question: how to use the depacker (fw) to depack at a given address?

[shazz]

Salut Emmanuel,

I tried to use the 6502 depackers so I think I don't use it well.
I need the depacked data to be at a given address ($1000) so I have setup up:
apl_srcptr: end address of the packed data
apl_dstptr: start address of the given location I need the depacked data

the packed code is at $3000 and the destination address is $1000. Here is how I call the routine:

          lda #$00                                                                                  
          sta $fc                                                                                   
          lda #$30                                                                                  
          sta $fd                                                                                   
          lda #$00                                                                                  
          sta $fe                                                                                   
          lda #$10                                                                                  
          sta $ff                                                                                   
          jsr apl_decompress

But after decompressing, the result at $1000 doesn't look like the original data. What's my mistake?

Thanks!

Ah I found out finally, the good depacked data is located 126 bytes after the destination buffer address, so I set the destination buffer to $1000-126.
Is it always 126 bytes?

Ah silly bug on my side. Sorry/
