I found the cause of the problem. If I uncheck the EnableRecompiler for EmotionEngine in SettingsAdvanced, the chair seems to be placed on the floor correctly. RahXephon Limited Edition _SLPS-25264_eeRecompilerDisable RahXephon [Limited Edition]_SLPS-25264_eeRecompilerDisable.gs.zip

Interpreter use "Nearest FPU" rounding, maybe that's all you need to set for recompiler?

It's something else than rounding. Falling back to interpreter for DIV.S fix it. So i tried to figure out differences between int and rec here. But nothing worked so far.

For rec i tried:

  • Enter div by zero even when only exponent is 0 (didn't tested 0/0 that way though, game do both div by 0, and 0/0).
  • Allowed negative clamp for result (-fmax for - inf and below)

still an issue and EE int still fixes it as of v1.7.5316 image

Sorry I forgot to mention it here earlier. It turned out to be FPU DIV nearest rounding when i tested it later back in March. Previously i assumed that fpu use nearest rounding for interpreter as in old pcsx2, apparently that's no longer the case. Anyway, it worked with removed force rounding, iirc also when set to positive (for DIV).
