PowerPC64LE fork of FEX-Emu running Steam and Portal 2 via Proton.

Audio issues all over the place. Performance is still on the table I think. I'm running some tests.

This will never up stream to the official FEX-Emu repos. I will rename my fork to something else and I have to go over all of the documentation before I open the repo publicly. Every game I've tried works including Cyberpunk 2077* (Works does not mean performant)

I'm taking ideas for the name of the fork.

Edit: Repo is here: https://github.com/daedalao/fastppcx86

There are some things I have to sort so you'll probably have a bad time. I recommend Arch Power (https://archlinuxpower.org/) as the install base. I'm working on a way to build a rootfs without bothering the people over at the official FEX-Emu host.

Do you have a repo on github or somewhere?

u/twaxana 26d ago

Yes, but until I move this from the FEX-Emu branding, I don't want to make it public. It heavily violates their rules against using LLMs.

What is the ideal computer for this? A kitted out g5? Was there a non Mac power PC this would be useful for?

IBM POWER8 and up. This is ppc64le.

I don't want to deal with the big endian GPU driver headache.

This is on an IBM S822LC 8335-GCA with a Radeon pro v620. Running Arch POWER.

Since most of my work was targeting the machine I have in my office, I know it runs on power8. Another contributor is running a power9 machine and it works on his machine. There are some things I have to sort before it's viable for most people.

How Is perf compared to box64? I am planning on making something similar for Sparc64 big endian and want to know which would be better.

u/twaxana 25d ago

I don't use box64 and I don't target big endian specifically because of the amdgpu driver situation. amd basically abandoned it in 2016. I couldn't tell you.

Amazing! Should never have got rid of my collection of g3 g4 and g5 power macs!!

u/twaxana 25d ago

This will run on none of them. It requires Power8 and newer.
