N64 ROM hacking noob, in need of some assistance
Nevermind, I finally figured it out. I read on here that if I remove the quotes I have to add underscores in all the spaces. Probably really simple for everyone else, I didn't know. Thanks so much for all your help, I was finally able to apply the patch!

Does epub compress well?
You should look at Precomp - an apparently abandoned, but awesomely working arhiver that is dedicated to compressing those ZIP-based formats, and compresses them twice-thrice as small as LZMA2 can.
- Any suggestion for compressing a large batch of photos and videos into a single zip?

Putting 5,998,794 books on IPFS
You can also have a look at this packer. It compresses PDF and EPUB 2-3 times smaller than 7z at maximum settings, at half the speed. I keep all my books in it and never had a problem.

libgen currently adds around 1,300 books a day
There is an opensource archiver called precomp that is designed specifically for e-documents and compresses them 2-3 times smaller than 7z in ultra mode. It works, and I keep my e-books in it. However, it seems nobody else does, and development has stopped due to lack of interest.

AWS switch from gzip to zstd – about 30% reduction in compressed S3 storage
There are tools like preflate [1] or precomp [2] that guarantees a bitwise identical reconstruction, of course modulo bugs.

Which compression method for archiving OS ISOs?
You may use "precomp" in order to seek and uncompress those parts. Then you can use a better compression algorithm : http://schnaader.info/precomp.php

Is there any research as to what's the best way to compress each file type?
Precomp http://schnaader.info/precomp.php is a program which will seek compressed parts and decompress those parts in order to compress with another algorithm. This greatly improve compression ratio with the other algorithm.
