[Help] Clover setup for ASUS Rampage V (i7-5930k) with High Sierra

Years ago I was able to install macOS High Sierra + Windows 10 + Ubuntu on a single drive, and over the years, things broke (unrelated to the triple booting). I cannot for the life of me remember how I got Clover working for the X99 system. I swear I remember reading through the guide "How to extend the iMac Pro to X99" and maybe had to tweak a couple of things, but absolutely nothing is familiar at this point.

I cannot (to my knowledge) upgrade to anything past High Sierra thanks to NVIDIA. So I'm trying to recreate what I did a long time ago. The EFI partition on my USB install drive seemingly got overwritten or corrupted at some point, and Clover has been borked on my desktop for a while, so I don't really have much to reference anymore.

I've tried the EFI folder from the linked guide, and when trying to boot into the installer, I get slide errors. Setting slide=0, I get a little further, but it gives me a printf error. Tried a modern Clover install, copying the kexts from the guide, and it does not show macOS at all. It appears that the drivers folder got renamed/moved at some point, and while the "off" subdirectory contains the "APFS" driver, I'm not sure the driver is in the right spot? I'm really beyond lost trying to figure out what's changed with Clover since 2018.

I read there's OpenCore now, which I'm very unfamiliar with. I'm hoping it can boot Windows/Linux as well? I suppose I can give it a shot, but based on reading the OpenCore guide, I'll need to break into my macOS install somehow to make the flash drive again.

What's my best plan of attack here? I'm rambling and lost, and I'm sorry guys...it took me so long to figure out clover back in the day, and my brain is not what it used to be.
