DEITM049.ITM Error Options

[BeachBum]

I am in the middle of installing Big World and specifcally the Lost Crossroads Spell Pack for Baldur's Gate 2 = SpellPackB5 and am encountering an error.

When trying to install the Core Files and Graphics it fails with the following error. "DEITM049.ITM: read out of bounds".

Can anyone help resolve this.

Thanks.

I see, but I asked what mods (or perhaps the original game?) add these corrupt files. Normally, such horribly broken files shouldn't occur often at all. If they do, it means something is corrupting or has corrupted game/mod files.

[..]then we assume the last feature block didn't get filled in

Filled in by what? A WeiDU installer of a mod? If so, we're talking about mods which produce broken files (I don't refer to the question of mod quality now, I am just wondering).

On a side note, in case of DEITM049, nothing was broken in such a cruel way (i.e. end-of-file in the middle of a block). It just had incorrect feature block offsets (indexes) assigned (if I remember correctly, their value was greater -- or smaller? -- by one than the actual position).

Filled in by what? A WeiDU installer of a mod? If so, we're talking about mods which produce broken files (I don't refer to the question of mod quality now, I am just wondering).

A .spl or .itm file consists of a single 114 byte header, multiple (56 bit for .itm and 40 bit for .spl) extended headers, and multiple 48 byte feature blocks or "effects".

I once ran a test on one of the corrupted files, and found out there was nothing wrong with any part of the file except the last effect in the last header. When I READ_SHORT the opcode, the installer ran out of bounds and bailed out. When I opened the .spl in DLTCEP and looked at that effect, I noticed that all fields except the opcode number were filled in their default values - zeroes.

Therefore, I am making a guess that the last effect in the last header wasn't filled out to 48 bytes and that DLTCEP filled it out correctly. What I am talking about if I could replicate this correctly in WeiDU, and correct corrupted files on the fly rather than worry about them individually or going up to each modder or skipping them altogether.

But then again, I could be completely wrong, since I did not do -- what they call -- rigorous testing.
