I was wondering if someone mapped out IDs of imgol #s, sprol #s, and/or sound file #s onto a list.

DatEdit/PyDAT have searchable lists. IceCCUI/PyICE also have lists of all image/sprite IDs, but they aren't searchable.

IceCC had a lot of unknowns listed, and DatEdit's did not match up correctly when I tried them in iscript.

DatEdit's are definitely correct... Are you sure you're using the correct values?

Which tools are you using and what are their versions?

In DatEdit v1.4
For sounds, I use the number next to Sound File:
For sprites, I use the number next to Images File:

I use IceCCUI for iscript

Sounds are one number off (because of the numbering).
You use the sprite number for sprites and the image number for images.

The IDs included in DatEd and PyDat are 100% fine, unless there is something that I do not know of. For a text resource, check this out:

I made it years ago, but it should be still actual, for all I know.
