Here's the story so far: I've been trying to use a custom FRM file of the 10mm pistol for a custom 10mm pistol I'm making.
First I asked how to import the file into the game, to which NovaRain helped by informing me to look up the inven.lst and add the .frm filename into it:

It was after importing that I discovered that while the file appears in save editors and in the Proto Manager (the one from NMA), the icon doesn't appear in game on the hotbar or when you access the inventory. The only way you could even tell that there was a weapon was by looking at the sprite and seeing that the Chosen One was wielding a pistol. I brought this up to NovaRain, and we began to troubleshoot what exactly was going on. I mentioned that when I moved the file into the data folder inside the data folder (see below for reference), the inventory icon would appear as a fire gecko pelt, and Nova stated that there might be some conflicts going on in the inven.lst, and it turned out that I didn't set the the Proto Manager up correctly.
After I started off again with a clean Fallout 2 with the RPUv26, I reinstalled my resources, remade the pistol and reincluding the .frm, but it still didn't show up in-game. Trying to figure out what was going on, I made a custom sprite of the Ithaca M37 from Fallout: Tactics for Fallout 2 using Photoshop, converted it into a .frm file, and made a new proto for it, in which it also appeared invisible in-game.
I'm feeling frustrated because I don't know what's causing this. The custom FRMs are the only ones that don't appear in-game. I tested the custom protos with base game sprites, and they appear in the inventory and hotbar in-game.
Right now, I'm going post this along with screenshots of my resources and Fallout 2 folder because I don't know if anything here is causing this, and I need help.

Many thanks to NovaRain for the help they provided. They have been much appreciated in this venture into modding Fallout 2.

Ithaca M37 sprite I used (made in Adobe Photoshop, v24.7.1)
My Fallout 2 Data folders
My inventory folder at Fallout 2/data/art:
