After tedious bisecting with BOX64_NODYNAREC, I found that this opcode was not correctly implemented. However, a strange SIGBUS error pops up when I'm trying to run YuanShen.exe (Genshin Impact) with this patch. If the fix is only applied to VMP areas (by checking addr in dynarec), the program can produce a meaningful "A debugger has been found running in your system.\nPlease, unload it from memory and restart your program." message instead of garbage as before.

Does that means it's not ready to merge yet?

Ready to merge. I've tested wine explorer.exe and Flatout, and both are working.
