ptitSeb/box64 v0.4.2

on GitHub

What's Changed

• This version add lots on unconnected new things, like a PPC64LE backend, Vulkan overlay support or more Dynarec finetuning!
  => Vulkan x64 overlay support. That means using the linux version of Steam, Fossilize & GameOverlayUI will work.
  => Many dynarec refactors, especially on ARM64 & LA64 with fixes to speed regression introduced with the the last 2 releases and improved compatibility.
  => Support for SteamRT3 & new Proton 11
  => New PCC64LE in the work. Not finished, but usable already. Note that the platform seems to use a 64k pagesize by default, so compatibility will suffer on this platform.
