PD will definitely be the next game to be fully (or near enough) decompiled. The dev behind that one is great.
If you're bored, his write up on the "Challenge 7 Bug" is great read: https://gitlab.com/ryandwyer/perfect-dark/-/blob/master/docs...

Hey there. You might be interested in looking at the Perfect Dark decompilation project: https://gitlab.com/ryandwyer/perfect-dark. The goal is to build source code that compiles into the exact same ROM, byte for byte. The project is currently 73% complete and is already incredibly useful for searching for things or seeing how particular logic was implemented.
New feature found in Perfect Dark! First documented after 21 years.

hahah yes the "0.0f" is different from "0.f" is different from "0.0" is different from "0" is a great IDO meme as well. One of the changes we had to make we started to support the PAL release, which was compiled at -O2, was to go back and change some constants from explicit "1.0f" to "1" to get the code-gen to match.
I think that that is a C thing, though: an unpostfixed 0. is a double. Sometimes IDO can do the conversion at compile time, and sometimes it can't. But, the compiler will treat things "0.0f" and a compile-time "(f32)0.0" as different constants...
We have a kinda outdated document of weird IDO behavior which is worth a read if you want to trigger some PTSD: https://hackmd.io/vPmcgdaFSlq4R2mfkq4bJg#Compiler-behavior
Also, since SGI/MIPS/IDO was from Stanford (I think...?), there is actually a surprising amount of published papers on IDO's compilation model. Which comes in handy if you are trying for the ultimate joke of decompiling the written-in-pascal compiler into C: https://github.com/n64decomp/ido
