The IDA database was a joke to make. The functions in the executable almost always followed the same order as the source code and there were plenty of strings to follow. I really just eyed the op codes to see if they matched the source. It was really no big deal. Anyone with even a limited grasp of x86 op codes could have done the same.

Of course, ace from a wad file. I suppose in my mind I was thinking of something that would be innocuous and could contain malicious/joke code. I'm not sure why that was my thinking, but this obviously covers that. The only other consideration that comes to mind is code that can run as early as possible or avoids using a map slot. There has been some discussion in this thread about the usefulness of this for Doom modding. I haven't really read any of it (just skimmed), though I can guess what all was said. Certainly some standard community derailing of any vanilla hacking fun. Just thought I'd throw my 2 cents in, even if it's already been previously stated. This is really cool and I'm quite pleased that you took the time to work on this project. Feels like checking something important off a list. However, I'm not sure why anyone would want ace for modding. The idea was (in my mind) to surreptitiously run code with the player being none the wiser and then be surprised by the results. It's just a wad file right? Nope. But that's it. While you can do it with ace and it has been done, why? Outside of proving it can be done, which it has. It would make more sense to extend the original engine using a patched exe or a loader. Not to mention that we already have a compilable DMX supported DOS source port these days. It might even have dehacked support. So, once again, really cool stuff, but an odd roundabout way to mod Doom.

No, thank you! Playing snake while watching Doom demos play in the background is not something I would have ever expected to see! I'm very glad someone tackled arbitrary code execution in Doom. There just had to be an exploit somewhere. Doom's highly unchecked save behavior was certainly the hot spot. Now I'm curious if there's some means using a wad file...
