Invalid opcode error #1153

Open MatPoliquin opened 2 years ago

MatPoliquin commented 2 years ago

I get "invalid opcode" error message (can be seen using dmesg command) when running retro_arch on lakka linux. I tried Crazy Taxi, Daytona USA and Shemnue As you can see my hardware is quite old but it seems it still meets the instruction set requirements

Any idea?

info:

Flycast version fd50529
AMD Athlon(tm) II X2 220 Processor (MMX MMXEXT SSE SSE2 SSE3)
Geforce 8200
Lakka linux

Note: I get the same error on my macbook pro mid-2010

which version of the core?

unfortunately I already deleted it but I tried this newer version (fd50529) and it works.

I also just tried a much older version of flycast and I no longer have the issue. I found it here: https://github.com/bite-your-idols/Gamestarter/blob/master/packages/libretro-cores-Gen/flycast_libretro.so

Can you upgrade to the latest version of the core to check if the problem persists? Version fd50529 is 2 months old and the older one is 2 years old!
