[1.10] Uniqueitems.txt file limit

[Xaphan]

Hello all,

In this topic, it is said that the current row limit for uniqueitems.txt is 4096. It is also said that it should be easy to expand. Doses someone already tried to expand it, or know where and what I should do to increase this limit, to, say, 16384 ? (4x higher)

Thanks for any answer.

Edit : none know how to do this ?

Edit 2 : Bumping this again, just in case

IIRC the limit extends from the savebits used to store the unique item index (12 of the top of my head), expanding it requires changing the constants in the save read/write code and the item sync code.

Ty for answer.

I will see if I really need to increase it or not.

I'm also looking for an answer to this. I am working on a small project and would be interested to see if anyone has a solution for the limits on UniqueItems.txt. No luck finding a d2mod plugin to expand file limits

This is what I found that needs to be changed so far. Don't know if there's more. These edits will allow up to 32,767 unique items records.

This is on version 1.13c, but these should be easy to find on any 1.10+ version. It is also to note some of these also control set items limit, which apparently also is limited to 4096 records. (but why not getting rid of it at the same time, right??)

That's the savefile stuff Necrolis mentioned (these will corrupt your savefiles, be warned), although there is more to do... The pGame data holding nolimit flags can only hold up to 4096 flags. Personally I didn't need to expand this (or to use it at all actually) and just replaced all code using it in order to get rid of it. If you don't want to do this, you will have to expand the allocated data for this.

The functions using this data are also usually full of (if nIndex > 4095) checks, so you will need to change all of these as well.

I found the codes in d2game.dll,but it's hard to find in d2common.dll.Some codes is diffirent.
Could you tell me how to find this?
