Oldies - The "Submarine" series of Big Panda and others

This is one puzzle a little enigmatic: first, for his interesting structure; second, for the numerous versions that have been made, and, above all, for the unusual amount of unsolvable versions.

The original puzzle is a work of the chinese Big Panda, and in the remodels intervened York Shen, LZY and may also others. Most versions were published in the old forum chinese SuperSoko, toward 2003 or 2004. I've entertained in: 1) to collect all the versions (if you know some version not collected here, please send me it); 2) to solve the puzzles; 3) to establish a logical ordering of versions. I lost a lot of time to make sure that the unsolvable puzzles, indeed, have no solution. However, I may be wrong: if you find a solution of any of these "unsolvable" versions, please, send me it or post here.

In the series I have also included the remodels made by Marko Dzekic (which gave the name "Submarine" to this puzzle). Almost all of the remodels of Marko are arrangements of unsolvable versions.

It is not a difficult puzzle, and it's nice and fun to solve. Most of the versions are similar, although all of them are interesting. In my opinion, the best is the latest version ("p"), of LZY and York Shen: is the version more tighter, and therefore is also the most difficult.

If you have more information regarding this puzzle (date on which was published, authors of versions...), you could write a comment on this post.

Arrangement of the previous "o" version. It is still more tighter than the "n" version, because it is necessary to take out all 7 boxes from the bottom center.

New additions

Přemysl Zíka sends me this fantastic version, with *one more box* (!) over the last "p" version. I confess that I have not found the solution on a first try... :s
