• Many questions!
  
  I didn't added charts comparative time & size about Shrinkler because it's so different (timing chart with shrinkler,l-packer,cranker and upx would have weird scale ). I like the X speed vs Y size chart idea. But takes time to build such a chart (including the two platforms). If anyone want to do it, feel free :)
  
  Regarding license, I select MIT by habit in github. Obviously you're not required ot credit L-Packer in a prod, no worry!
  
  About depack mem and exe overhead you can use the verbose (-v) option to get more details about that.
  
  Shrinkler estimated time depends on the exe obviously, but some 64KiB takes 30 sec to depack. One coming in mind is the great Coda by Abyss ( 32 seconds on A500) https://www.pouet.net/prod.php?which=80998
  
  Finally about adding algorithms, Titanics, Powerpack, Doynamite are same league regarding speed, but slightly worst regarding packing ratio, so I won't include them. I plan to include LZ4 because it doesn't pack well for sure, but it's really fast to depack. So if your prod still fit the target size and LZ4 could be used, it's even better.
  
  Hope it helps! Thanks for your nice feedback!

• just updated to v0.92. Now Amiga version also supports depack-in-place

  Nice ! It's a little over 64kb, but not by much, so it can probably be improved.

  
  
  Yes, nothing could beat arithmetic coder of shrinkler (or STrinkler on atari). L-Packer is made when you can't afford too long depacking time with large exe such as 64KiB or more. So it's expected to be bigger than shrinkler, but should be smaller than any other amiga exe packers ( I hope :) )

  The three intros are in Amos, so they have a similar structure. If you want, I can provide you with the uncompressed exe files.

  
  
  Yes I know Amiga bootstrap is not fully compatible right now (doesn't work with C compiled stuff). Probably same issue with AMOS exe. I have to investigate that for future v1.0. Ok you can provide an uncompressed AMOS exe so I can have a look

  I'm waiting for the no-flash option :)

  
  
  I just added the option, please download again :)

• L-Packer is a new Atari & Amiga executable compressor! Optimized for 64K-style demos, it balances high compression ratios with decent decompression speed. To sum up it stands right in the middle between Shrinkler and Cranker/UPX. Currently support both inflate & ZX0 algorithms. More technical details here: https://github.com/arnaud-carre/L-Packer
  Testing & feedback are welcome!

• final version available. What changed? It beta tests my new exe packer suited for 64k-ish demos, targetting both Atari & Amiga!
  
  Just use the same download link to get final version
