(And erm, yeah, if you are doing advanced BAM manipulation for stuff like animations, drop me a PM... might be able to hook you up...)

Done.   Been away from BG and IE games and modding, but the stir EE raised has brought me back home, at least for now.

nope. I cannot open the new audio files in ANY way.

They're simple OGG files. Extract them from biffs with weidu (weidu.exe --biff-get whatever.wav), change extension to .ogg and play with any decent music player (foobar2000, winamp, windows media player, etc.) to see what's in them.

DLTCEP menu option Sound -> WAVC to WAV will also correctly extract and convert them to old-fashioned WAVs which will be recognized by non-EE games.

Tinkered with it a bit more today, I think this should do it:

Basically, just added skipping any frame with frame size 1 x 1 or less - those "pixel" frames are really useless for editing, and if anyone needs to reinsert them later into modified animation bams it should be easy to just clone any one of them with weidu.  Rakshasa animation, as it happens, contains tons of those, so this greatly speeds up conversion process too. The loop index variable still goes up for skipped frames, so for example if out of 100 frames 14-65 were skipped, you'll get *0.bmp through *13.bmp and *66.bmp through *100.bmp in the output folder.

Hey Miloch. I'm hitting an error when trying to convert standard rakshasa animations (MRAK*.BAM) to bmp. It successfully converts first 14 frames but on the 15th this happens:

Converting frame 15 (compressed): reading datasize -21067 from offset 23429 ...
ERROR: illegal 44-byte read from offset 3080 of 0-byte file INNER_PATCH "%fm%"
ERROR: [MRAKG1.BAM] -> [bambatch/bam/MRAKG1.BAM] Patching Failed (COPY) (Failure("INNER_PATCH \"%fm%\": read out of bounds"))
Stopping installation because of error.

Looks like the patching goes on even if the calculated frame size was invalid.

Area Tilesets use the PVR format (which is uneditable ATM) as well. BGII:EE also introduced 32-bit bitmap files which is a new format to the Infinity Engine and which NearInfinity can't handle yet (although DLTCEP might can).

Yes, but old TIS tilesets are still accepted and will work just as well (so there's no need to wait for new tools to create a new area for your modding needs). New tilesets can currently be loaded in latest DLTCEP (use "Load MOS..." option) and exported as bitmaps/TIS, although not without problems (resulting images/tilesets have visible graphical glitches aka "tears" at tile borders).

Item description images is the only serious problem I've hit in modding BG2EE - old BAMs aren't displayed at the moment, but as I understand this is going to be fixed in a future patch.

EE only uses new formats for GUI files (+worldmap mos I think) though. And it will work fine with v1 bam and mos files too. So unless you intend to modify the new gui, there really is no reason to wait. Unless I'm missing something.

The following TP2 code will copy all V2 files in the game into "BAMBATCH/V2" subfolder if you want to check out a complete list of what's "uneditable":

COPY_EXISTING_REGEXP GLOB ~.*\.bam~ ~override~
	READ_ASCII 0x4 ~version~ (2)
	PATCH_IF ~%version%~ STRING_EQUAL_CASE ~V2~ BEGIN
		INNER_ACTION BEGIN		
		COPY_EXISTING ~%SOURCE_FILE%~ ~bambatch/v2~
		END
	END
BUT_ONLY

COPY_EXISTING_REGEXP GLOB ~.*\.mos~ ~override~
	READ_ASCII 0x4 ~version~ (2)
	PATCH_IF ~%version%~ STRING_EQUAL_CASE ~V2~ BEGIN
		INNER_ACTION BEGIN
		COPY_EXISTING ~%SOURCE_FILE%~ ~bambatch/v2~
		END
	END
BUT_ONLY

so where one would find updated tools?

http://sourceforge.n...es/DLTCEP 7.6g/

Not a modding suite per se, but a game files editor (which is enough to do almost anything you'd want, including a total conversion of the whole game). Yes, it should be compatible with both EEs.

Updated original post with current version, readme and download link.

Big thank you to Miloch for maintaining the mod and (apparently) fixing my mistakes. My apologies for this.
