[pFBNeo PS4] CAVE CV1000 games slow FPS

[mat999io]

All the CAVE CV1000 (B / D) games are not playable in PS4 because they run extremely slow (FPS and bad sound). A normal PS4 should be able to run smoothly a SH3 CPU with no 3D GPU.

Please check it, because these boards have some of the best modern Shmups:
