[THE-COPS]

Ok, here is what I have found out so far. In the last half hour, I quicky tested out 15 more Genesis games. Here is the list, and the results. All tests were done with sound set at 44khz 16Bit Stereo sound. Mostly default settings, including display and auto frame rate.

688 Attack Sub - Works + lower soundtrack missing.
Altered Beast - Works , sample rate for voices way too high
Boogerman - Garbled/Distorted GFX. Only character is visble. Music missing in game.
Beyond Oasis - Works. Minor snd gitches
Buck Rogers - Doesn't work. Get ROM generated error code at top "000FE006 03 " . May be a bad rom.
Castlevania Bloodlines - Works but a little slow
Crusader of Centy - Works. Static in some of the lower sound frequencies
Devilish - Works , game is a bit slow though
Flashback - Works , minor snd issues
Hard Drivin - Works, sort of. This one is complicated. Game will start but the road texture continues to vanish as you move towards it, forcing your car to constantly be "Off Road". SG crashed after 20 seconds of this.

Landstalker - Works, But gameplay is slow and a little choppy. Bottom portion of screen gfx don't refresh correctly , showing distorted gfx from another part of the screen
Light Crusader - Works, minor snd issues
Phantasy Star 2 & 3 - Works. minor snd issues.
Rings of Power - Works, suprisingly well. other emu's couldn't get this one right. Just minor snd issues
Sonic the Hedgehog 2 - Works. However , in 2 player split screen mode, the entire screen gfx are all distorted . Only characters are visible in this mode.

Will test more later sometime.
