Problems with new kega fusion

Anyone knows why the new KEGA FUSION sega cd emulator keeps freezing.
I got the BIOS for US , EU, and JAP installed in to the emulator.
I can play FINAL FIGHT and SONIC CD no problem.
But when i try to play some games, my game freezes on the SEGA logo.
I have try 3 different roms and i have the same problem.
SOL-FEACE and REVENGE OF THE NINJA are the game that i want to play again.
But it just keeps freezing up on the SEGA LOGO every time.
Anyone knows what im doing wrong.,?

Sorry for the late reply but be sure to check "Perfect Sync" in Options.
