Loading PS-X EXE causes unresolved exception [LFC-002]

[spacepaw]

First of all, I'm very impressed by how good Avocado's emulation is.

I tried various emulators to run homebrew, demos and intros, but Avocado is by far the most accurate for me. Avocado runs most of these files really well, but here is one production that doesn't start though.

Informations

Game: lfc-002 (not a game, but intro)
Version: windows64-20201221-2fd5325
Hardware: AMD Ryzen 9 3900X, GeForce RTX 2080, 64GB, Windows 10
BIOS: SCPH1001

Behavior

Loading the PS-X EXE file causes Avocado to output the following exception:
←[31mUnresolved exception←[0m: ←[1m←[37maddressErrorStore←[0m (5), epc=←[34m0x80010aa4←[0m, ra=←[34m0x00001b10 ←[0m←[34m0x80010a8c: ←[0m←[37mlb at, -0x3220(zero)←[0m ←[34m0x80010a90: ←[0m←[37mlb at, -0x3218(zero)←[0m ←[34m0x80010a94: ←[0m←[37mlb at, -0x3210(zero)←[0m ←[34m0x80010a98: ←[0m←[37mlb at, -0x3208(zero)←[0m ←[34m0x80010a9c: ←[0m←[37mnop ←[0m ←[34m0x80010aa0: ←[0m←[37maddiu sp, sp, 0xffe0←[0m ←[34m0x80010aa4: ←[0m←[37msw ra, 0x0018(sp)←[0m←[1m←[37m <---- Caused the exception ←[0m←[31mThis is most likely bug in Avocado, please report it. ←[0m←[1m←[31mEmulation stopped. ←[0mEmulation stopeed, see console for logs

You can download the PS-X EXE from the pouet demo scene website: http://www.pouet.net/prod.php?which=34346
You can also find a screenshot and youtube video of the PS-X EXE on that same site.

@spacepaw Indeed - I'm able to load the .exe on PSX without any issues while it crashes on Avocado.
It's a wild guess, but I think it might be a CPU bug on my side.

Thanks for the report, having isolated test cases like this demo program makes my life much easier.

That's good to know. In this case I can file a few more reports where I found some visual glitches in such demo programs.
