Here is a small list of what I currently have on my SMC & whether it works or not...
Road Rash 1 & 2 - works near perfect. Only thing I noticed with Road Rash 1 is a couple of the 'instruments' in the music aren't played. No biggie!
Wonderboy In Monsterland - Works but can get a bit choppy (use a high clock setting) & the graphics get totally messed up in places, mainly OK though.
Sonic 1 - Works fine. Only thing I remember is that in the demo (before you press start), one of the levels has a few graphics errors I think?
Sonic 2 - Works fine for me so far, but can get a bit choppy in places. Use a high clock setting if possible.
Hellfire - This worked in the previous version of DrMD, but I can't seem to get it to work in version 2??
Decap Attack - Doesn't work? I dunno if I have a bootleg rom or something, but the graphics are all messed up & it looks like a totally different game (from what is visible!).
Golden Axe 1, 2 & 3 - All seem to work perfectly for me.
Double Dragon 1 & 3 - DD3 works perfect, DD1 seems to also, but I'm not sure if the sound effects are correct? I never had DD1 for my Genesis so can't really comment, but there seems to be a lack of sound effects (as in crunching/punching noises & screams etc). Maybe thats how it was anyway?
Prince Of Persia - Seems to be perfect so far.
Robocop vs Terminator - seems to be perfect.
Mickey Mouse Castle/World of Illusion - Both seem perfect.
Alisia Dragoon - Seems perfect.
Moonwalker - perfect.
Alien Storm - Seems perfect.
Gunstar Heroes - seems perfect.
Altered Beast - perfect.
Cool Spot - Seems perfect.
James Pond 2 - Seems perfect.
Mortal Kombat 1 & 3 - seem OK.
Samurai Showdown - Seems perfect.
Thats all I can remember right now. I have more which I've tried but forget what they are (I'm at work right now, abusing the internet policy!). :unsure:
