Neither Final Burn Alpha core appears to play games based on the Psikyo SH-2 hardware properly. I went ahead and tested this with every known game that runs on this hardware.
Using the FB Alpha core (FB Alpha v0.2.97.30), the audio appears to be pitch shifted up (tested with audio sync on and off). Using the FB Alpha - SVN core (FB Alpha v0.2.97.38), the colors and graphics appear massively distorted (below image is of Dragon Blaze). The vulkan driver also flips the image for some unknown reason on both cores (another bug?), this flipping does not occur using the gl driver.
This occurs on Daraku Tenshi : The Fallen Angels Dragon Blaze GunBarich Gunbird 2 Mahjong G-Taste Sol Divide Space Bomber Strikers 1945 II Strikers 1945 III / Strikers 1999
