Unimplemented Opcode (66 66 2E 0F)

[LilleAila]

Hello,

I'm trying to run factorio through box64 on asahi, running nixOS. When running box64, it gives me this error:

710467|0x20f3450: Unimplemented Opcode (66 66 2E 0F) 1F 84 00 00 00 00 00 0F 1F 84 00 00 00 00 00

Here is the full output from box64:

I tested factorio on my M1 a few days ago (running Asahi Fedora Remix), and didn't had any issue. It ran correctly. Also, that opcode seems wrong, and looks like a loop alignement opcode with 4 skipped bytes, wich looks strange. Is this the latest factorio version?

[LilleAila]

This was with factorio version 1.1.104. I can test later if the latest version 1.1.107 works. Also, box64 was compiled with these flags:

cmakeFlags = [
  "-DNOGIT=ON"
  "-DARM64=true"
  "-DARM_DYNAREC=true"
  "-D M1=1"
];

I tried downloading the latest version, and that launched and ran perfectly. Maybe the old one somehow got corrupted ¯_(ツ)_/¯. Anyways, thanks for making this amazing project! Now I can play factorio again!

[ptitSeb]

Nice! Glad it works :)

The ticket can be closed right?

[LilleAila]

Yes, i got it to work
