No.11900 Tafoid Administrator Jul 27, 2015, 14:35	Correct. It covers all m62.c games if the discrete parts of the boards are used in the game (usually for drum effect) or not. There is an argument that all the games should now be flagged with "THE SOUND EMULATION IS NOT 100% ACCURATE" which will likely happen. But, as it stands the slowdown is expected so there is no bug other than the sound quality issues which are being worked on. Closing
