I finally got around testing DM 2.9 and here's what I got:
**Fixed Features**
-Billy Hatcher and the Giant Egg is fixed
-Need For Speed Most Wanted is fixed
-Other games I've tested like Luigi's Mansion, Mario Kart Double Dash, Super Smash Bros. Melee, Rayman Arena, Sonic Adventure 2 Battle, Crash Bandicoot The Wrath Of Cortex... etc all worked fine with no problem (except for audio streaming of course) soft reset works too
**Broken Features**
-2 Disc support is broken (tried it with Resident Evil Code Veronica and TMNT2)
-Phantasy Star Online Episode 1&2 no longer works
-Soft reset still doesn't work with Batman Vengeance (it never worked in any previous versions)
**Unfixed Issues**
-Spider-Man The Movie still requires a disc to be in the disc drive, haven't tested Sonic Gems Collection though since I've switched to Devolution for this game a while ago and it works fine with no disc, can someone confirm wither it still requires a dics in the drive or not? Just for testing
**Games I Didn't Test That Didn't Work Before**
-Kao The Kangaroo Round 2
Looks like I'm switching back to DM 2.8 Mod until 2 disc support is fixed at least!
