I’ve been playing on 2DF for more than a month now, and I’m starting to really like it. Mainly because the lag on 2DF is severely less for lb2. One of the down side is that there is no dip switch option, so there isn’t really any good way to avoid playing on laggy stages. On the plus side, I can play people from Asia, South America, and Europe w/ little or no lag issues. One thing I don’t like about kaillera is the input delay, and that’s not really a problem on 2DF. Also, there are a lot of really good players from other countries on 2DF, so the lb2 community on 2DF is much bigger than kaillera.
Well, my point is to people who still play lb2 on mame consider switching to 2DF, if possible. It’s much better for the above reasons.
