aplib decompressor for ZX Basic.

I would probably input the numbers manually or make a tool myself

Then you can use:

Code:

label:
asm
  defb 0,0,0,0,0,0,0,0,0,0 ;' your binary data
  defb 1,2,4,4,5,2,0,0,0,0 ;' your further binary data
end asm

As for decompression address you can make a buffer with a label in similar fashion, and re-use it for decompressing all levels one by one. I used similar method in "U-Boot hunt" to decompress all frames of the explosion in real time (I used the MegaLZ compression, because BorIDE can compress selected DEFB's with MegaLZ).
