Of course. But then again what's the proposed solution for that?
Anyway, I'm writing another script, this time on a different format:
Code: Select all
00000000 56 45 52 32 BC 01 00 00 07 00 00 00 FB 04 00 00 VER2¼.......û...This is the script I'm writing for the format:
Code: Select all
getdstring SIGN 4It'll be finished after I make a few tests.

A solution for the multiple archives can be like the one in the script for the warriors, search "LAST_ARCHIVE_NUM" in the script (the method can be done also without recording the currently open archive but it makes everything faster).

Huh. That's what I should have considered doing before deleting all the files I've tested with.
Anyways, I have two .IMG files(GTA3.IMG, GTA3_1.IMG, no .DIR file). Should I do it like this:
Code: Select all
getdstring SIGN 4

You have to read the ARCHIVE_NUM field from the archive and then building the name of the img to open.

I think I'm puzzled here, can you elaborate on this so that I can get the idea?

You need to locate the field in the index file where is placed the number of the archive to use, like to for GTA3.IMG, 1 for GTA3_1.IMG and so on.
As you said there is only one index file and 3 archives, right?
building the name of the package to load is simple:
Code: Select all
get TMP basename

The snippest of code I pasted loads GTA3.IMG if ARCHIVE_NUM is zero.

Well, maybe I didn't actually "read" the field but both of these files look strikingly similar.
GTA3.IMG Code: Select all
00000000 56 45 52 32 58 3F 00 00 FE 00 00 00 02 00 00 00 VER2X?..þ.......GTA3_1.IMG Code: Select all
00000000 56 45 52 32 58 3F 00 00 FE 00 00 00 02 00 00 00 VER2X?..þ.......Which is why I assume they're duplicates.

The GTA3_1.IMG is a duplicate of GTA3.IMG.If you have a PS2 version of GTA SA there is a file called 'FILELOAD.NM'.Open it in hex and search for 'GTA3_%d.IMG',replace it with just 'GTA3.IMG'.This will bypass the GTA3_1.IMG reading and you can safety delete GTA3_1.IMG.Just mod GTA3.IMG

...aaaand done. I'll consider that solution for when I actually feel like testing the game on an emulator or real hardware but for now I'll just release the script as is.

So far I'm working on a script focusing on the .bsa file.
Code: Select all
goto 0The index itself is at the very end of the file, as you can see here:
Code: Select all
00FFB5B0 30 31 41 58 45 2E 43 46 41 00 01AXE.CFA.The problem though is that when I test the script on debug mode, it doesn't detect the next file:
Code: Select all
- current_folder: E:\quickbmsAm I doing something wrong?

You return ever to -0x18, that's an absolute offset and not a relative one.

Probably you have to find where the toc starts by doing: xmath INFO_OFF "ARCHIVE_SIZE - (FILES * (0xe + 0x4))"

"OFFSET 4"... like this:
Code: Select all
get FILES short

Because 4 is the sum of the 2 shorts you have read at the beginning.

I'm still clueless, do I have to use both the two shorts as the starting offset for the files? I'm still thinking on removing the "goto -18" line but...
