Namco System 12 for MiSTer — 20260804

Tekken 3 and Soul Calibur, running at 60fps on real MiSTer hardware — plus six more System 12 titles.

Tekken 3 and Soul Calibur both play full speed with clean audio. Two new CPU-side optimizations:

• The R3000 was stalling on its multiply/divide interlock on every mul and div, which is where a surprising amount of the in-fight slowdown was hiding on some MiSTer systems. Thank you to the beta testers who helped validate the solution.

• 4-word data-cache line fill — the data cache now pulls a full burst per-miss instead of one word at a time, for free (no extra memory traffic). Roughly half as many cache misses in the hot loops.

8 Titles, 27 Versions

Fully play-tested on hardware:

• Tekken 3 (10 regional versions)

• Soul Calibur (8 regional versions)

• Ehrgeiz (3 versions)

• Fighting Layer (2 versions)

• Super World Stadium '98

New this build:

• Super World Stadium '99 — Namco's arcade baseball

• Libero Grande — 1-on-1 arcade football/soccer

• Oh! Bakyuuun / Ghoul Panic
