Atomiswave help Retroarch LB/BB (Solved)

[bv3]

Hi all, this has me stumped.

I'm trying to load Sammy Atomiswave games using Retroarch Flycast core. Whatever I do it does not work within LB or outside of LB with Retroarch.

If I setup a standalone Flycast emulator within LB it works but then I can't seem to find the right parameters for within LB.

I'm attempting to use the excellent Warped Polygon setup (thank you WP) but unfortunately.

When I try outside of LB in Retroarch I get 'cannot load bios awbios'. My working bios that I use in Flycast standalone is in the system folder of retroarch, so I'm not sure why it isnt working.

Within LB I have made sure that "Extract ROM" is unchecked, but to be honest, it doesn't appear to get that far as the bios wont load.

I'm using stable Retroarch release with 1.16 Flycast.

Any thoughts on what I can do to overcome this hurdle?

I wanted to EDIT the title to solved, as digging through some other posts I did manage to find something that led me to a fix. 

A previous post on Atomiswave/Naomi referenced how to use core information to ascertain what was missing.

Everything I have seen on RA seems to indicate that you just throw bios files in the system folder. Once I searched through core information all of the missing information had dc/ which appeared as if I needed the flycast bioses to be self contained within a folder named dc. Once I did this the issue was resolved. Thanks to @Jayinem for the assist.
