I’m interesting on core versioning for medanfen psx and bettle psx. Last version of medanfen psx emulator is 0.9.38.7 (1 october) => How to know what version of mednafen corresponding the mednafen psx core core? Bettle psx core is up to date with last change of mednafen? How to know it?

thanks for your information

Beetle hasn’t been updated in awhile and is now out of date. Mednafen-psx is closer to upstream.
