Reicast core dumps on loading any NAOMI rom

[Shoegzer]

Tested against build f59c772f00e5e706a06eb5ec9d041c97aa221f15, compiled on linux 4.18 x64. Older builds tested at least a few months ago worked, not sure exactly when but could bisect if necessary.

Loading any NAOMI rom returns the following:

$ ./retroarch -L cores/reicast_libretro.so "pstone.zip"

reicast doesn't see your rom, try with full path or without ""

[Shoegzer]

Thanks @barbudreadmon. Tried with full path and without "" and got the same results. I can do an "ls" of the rom and I can see results too, so the file is definitely there. I've tried with various other roms too and getting the same results. I used to use this command all the time and it worked fine not too long ago. Can you replicate?

[barbudreadmon]

Can you replicate?

Nope, reicast see my roms, what's your full path ? Are there spaces or other special characters ? Could you post the full log by adding -v to the command line ?

[Shoegzer]

@barbudreadmon Sure thing - check here. To be sure it wasn't a path issue, I moved "pstone.zip" to the retroarch folder itself as you can see from the output. This same file boots just fine in MAME 0.208.

Also, in case it makes a difference - I'm using GNU/Linux, not sure if you are?

[barbudreadmon]

[INFO] Environ GET_VARIABLE reicast_boot_to_bios: [INFO] enabled

You are booting to bios, it won't work with naomi (i guess we could add some safety mecanism), change that and it should be ok.

[Shoegzer]

Ah, naturally! Good catch - and yes, it works now so I will close this out. As a side note, I wonder how hard it would be to enable the core to trap such a condition (since DC BIOS is meaningless in NAOMI context) and optionally throw an exception to the UI rather than terminal.

Thanks so much for your help.
