I'm sorry if my post had a bad tone to it. I didn't mean it that way.
Also pretty much any Blazblue character(or pretty much any new age 2D fighter) for mugen is going to need a strong/decent computer to run. I am guessing you don't have a very good computer because a decent/good one should not have the problems you mentioned. Almost any character like that is going to be a large file size, a very large file size. If you have a weak computer you'll run out of memory eventually when using those types of characters. Even my computer still does this even for being pretty good. My characters, Neat's Nu-13 and many characters like this in the future are just simply going to need a decent/good computer. I highly recommend getting/upgrading your computer. I know this is WAY easier said than done but it's best if you do this if you plan to create these characters for yourself and to share with others. It works better over all this way. If you stick with a weak computer you'll miss out on a lot of new 2D fighter characters. Also if Mugen 1.0 just simply doesn't work well for you on your current computer, don't try to convert them to Mugen 1.0 until you get Mugen 1.0 fully working on your computer, with no lag and other problems.
All of what I said is only valid if your computer is weak.
BTW Neat's Nu-13 is like 300 MB and I run out of memory on my computer after using it around 4 times.
Little known FACT: If you use the equation, (z)velocity = (((x2-x1)^2 + (y2-y1)^2)^.5) / time and z = a small decimal number in mugen you can get something that follows something else. Useful for heat seeking missiles, black holes, magnet effects, a projectile aimed for an enemy's head... Seriously, try it! It's awesome!
Little known FACT 2: The denominator of 9 or 99 or 999 or .9 or .99 etc is the best denominator EVAR. If -99 < x < 99 and x is rational and not zero and use the fraction x/99 you WILL get a repeating decimal. Use this so you don't need to round a rational number EVER AGAIN!!
