GTA4 Decompiled Native iOS Port (WIP)

Leveraging a lot of knowledge from the Liberty Recomp and the rendering pipeline work from XeniaOS to help with the translation from PowerPC to Metal ultimately.

Two things came of this: I have a build of XeniaOS that now (with JIT needed) plays GTA4, driving around the city after the cutscene - haven’t tried a mission. Runs at about 20-30fps. Sound mostly okay, some desync from each channel.

The second is I now have a booted version of a custom arm64 compiled launcher and translation with Xbox 360 game files + TU8.

I’ve finally gotten a full picture output of the intro , and loads of”The Cousins Bellic” screen before crashing once it’s rendering 3D.

Lots of work to do but huge progress! Very excited to see where we can take this.

We, as in myself and SOL 5.6 and Astra. I’ve never made software or even attempted something like this before and was simply a thought experiment as I knew the recomp was worked on, and followed the same logic as the recent GTA5 port to android. Please dont flame me, I’m not a dev but wanted to share lol
