(Android) Do the recent coversions Atomiswave to DC roms work?

So, do the ‘converted to .gdi’ Atomiswave games work in Retroarch Flycast? I tried in Retroarch64 with latest flycast core and i get a black freeze screen.

To answer my own question (in case anyone has the same issue), the Atomiswave-to-DC ports work, but they “need” the DC bios in the “system - dc” folder. The normal Dreamcast games don’t need the bios with recent flycast core versions, so that was my confusion.
