Hacking Disgaea 2 - Dark Hero Days Looking the lost characters

[greenlanternx]

Since the last DLC for this game was released in 2010 (official info in us.playstation.com), I was looking for a way to include the lost characters (Gig, Dark Eclair and Miable) and maybe the NPCs (Toro & Kuro)
I found something quite disconcerting
1.) all decrypted DLCs are the same (Binary Comparison)
2.) if I rename the DLC with another name (DL_US_00 - DL_US_06) activate the corresponding DLC char, out of range (07->) are not detected....
3.) if I put another DLC (such as the jap dlc) with US name in range 00-06 the game dies, but with another number (07->) are not detected.
4.) unpacking DLC file with NISDecmp NISUnpack and La Pucelle Toolpack( by DragonRagnarok) I found the 3 missions (in DUNGEONS.DAT ) between the official releases (Another Princess - The Strongest Guy - Antiphona) but in talk.dat nothing related
Conclusions:
-NISA never planed to release them (I read in some forums about people who bought this game only for this characters, so NISA F@·½~ them , sorry)
-In somewhere in the game, is the code looking for DLC in range 0-6
-In somewhere in the DLC, is the logic to select the right character for the right slot (since in game code have no references to DLC missions)

I found anything else, I will update this thread

have a nice day
