I am hacking up my miniBB for the sake of giving the option to have an RSS feed per forum. I will probably share the code once I'm done, but there's one critical thing I can't seem to spot: where is the html that's generated per forum title? I need to be able to add a link to an RSS page prior to the name of every forum title, but I can't find the file holding the HTML that's rendered. Could someone point me in the right direction?

The template is main_forums_cell.html if you mean the first page.

You may use the current general rss2.php file for generating the feed for each forum, separately, just modifying the code a bit. Look at the example I provided in Storage:

https://www.minibb.com/forums/storage/mods/rss2-forum.zip

It can be used BOTH for generic feeds and separated by forum feeds.

So in main_forums_cell.html you need then to paste the link like

<a href="https://www.minibb.com/forums/rss2.php?forum=12">RSS</a>

That's the exact train of thought I was using! Thanks for the help. I didn't know this had already been partially done but I'll still share my results once I'm finished with the hack.
