An update to MM8BDM was released a couple weeks ago, and the unofficial classes mod got updated a month ago.
If you guys havent already tried it you really should, its pretty fun.
Vanilla MM8BDM is fairly simple shooter, with weapons lying on the ground, health & ammo packs, ect.
The classes mod makes the characters actually play like their original versions instead of just being generic skins..
Here's what classes it has so far:
-Megaman, ProtoMan, Bass, Duo, Roll, Dr. Light Hologram (plays like Ryu), Rock (Megaman Soccer/Megaball)
-Sniper Joe, Dr. Wily, Original Duo, Evil Robot (from MM8 Opening), Alien Wily, Doc Robot
-All the Robot Masters from 1-9 + OilMan & TimeMan from Powered Up, and FakeMan from 9.
-All the Robot Master from 10 except SolarMan, SheepMan, and StrikeMan
-The 6 new Robot Master from Megaman & Bass + King
-The 4 Darkman robots from 5
-Quint & the 3 Megaman Killers from the gameboy games
-The Genesis Unit from Wily Wars
-The Stardroids from the Megaman V, except for Terra, Saturn and Sunstar
