Problems with my wad

[CPLJigsoreQuandary]

Okay I've tried for a while to figure this stuff out on my own and I've hit a brick wall. So I'm just going to explain what I'm doing and hopefully somebody can help me.

 

I want to make a standalone game, an iwad. People keep saying "don't edit the iwad" but I do not want to just make an addon, I want this to be like Freedoom is. A standalone iwad. I've managed to figure out how to get my iwad to load into GZDoom with the other iwads, so that is not my problem.

 

My problem is that I want to edit the code for the guns but none of it is working. Specifically I am replacing the chaingun with the assault rifle from Marathon 2. I've already replaced the sprites with the ones I want, and I created a DECORATE lump which includes the code for the chaingun that I got from the wiki page. I then edited that code so that the animation frames are faster because the MA-75b assault rifle fires very fast but when I save the iwad and run it, the frames still run on the same ticks as the chaingun. I also tried to replace dspistol with the sound for the rifle, but still named it dspistol and that also did not change at all. Am I doing something wrong? Is there an easier way to do this?

I'm doing one as well but you still should make a PWAD, and then import into it ALL the resources the game will use. menu text, sprites, textures, EVERYTHING. Then edit with a hex editor to make it an IWAD when it's completely finished and self-sufficient. Editing the IWAD caused me trouble and was just an inefficient way of working due to all the useless stuff in there + you WILL forget some proprietery doom stuff in there. Just make a PWAD while you're working on it. That can solve your DSPISTOL issues at the very least :)

How would I go about doing that?

Open your WAD with an hex editor, and the four first bytes are either "IWAD" or "PWAD". when your PWAD is 100% complete just change PWAD to IWAD and save. It's better than messing with the stock D2 IWAD
