RPCS3 Mac Build (Apple Silicon)

A custom RPCS3 build for Apple Silicon Macs (M1/M2/M3/M4) with RPCN v1.5/v30 online support.

What Is This?

This is a patched RPCS3 PS3 emulator build that restores online multiplayer functionality on Apple Silicon Macs. The official RPCN server was updated to protocol v30 (RPCN v1.5), which broke online play for older builds. This build includes the necessary patches.

Base: RPCS3 0.0.37-18119 Patches applied:

• PR #17825 — RPCN v1.5.0 protocol update
• PR #18112 — Additional RPCN v30 fixes
