Standard, unmodified versions of RetroArch for the Wii suffer from severe bottlenecks. The Wii’s CPU is a single-core, 729 MHz IBM PowerPC-based Broadway processor with only 88 MB of total system RAM (24 MB of 1T-SRAM plus 64 MB of external GDDR3). When running a full-featured emulator like the base RetroArch build, the system chokes. The dynamic recompilers (dynamic recomputation) required for systems like the PlayStation 1 or Neo Geo demand more memory and clock speed than the Wii can natively supply. Furthermore, the input lag caused by RetroArch’s default controller drivers and the overhead of its graphical menu (XMB or Ozone) can push the Wii beyond its real-time processing limits.
Independent developers have released unofficial core updates (e.g., Snes9x2010, Genesis Plus GX) optimized specifically for the Wii’s architecture to reduce audio stutter and improve frame rates. 2. Performance Optimization Guide retroarch wii patched
