I've never had this problem (I use Brawlplussery + Momentum Capture v3 + Custom Default Settings + CCS). I do not use the stage builder codes.
BTW, great work promoting Brawl+, goodoldganon. This is just the kind of stuff we need to see from all our active members, especially now that B+ has reached a coherently finished product as far as general gameplay goes. I'm especially interested in hearing the reactions of more casual players. I showed it to several more friends and they had a blast with it (one friend who loved Link in Melee, but hated him in VB and early B+, fell back in love with him again...ahhh, romance!). The hardest thing to do is explain the changes made, and the added features.
What we really need, once the momentum code is decided on, is a simple video that explains Brawl+, the goals of the project, the changes made (with footage of vanilla Brawl used alongside Brawl+ footage for comparison), and the new techniques and their applications (dash dancing, dash canceling).
Things that should be emphasized,
*Risk-Reward Balance system (explain this first, as it applies to all aspects of Brawl+, be sure to note that unlike VB, B+ rewards risk taking aggression).
*Hitstun
*Gameplay speed increase (dash speed increase, ledges).
*Increased character balance (goal, all characters should be able to win a tournament. Avoid terminology like "viable", Vanilla Brawl should be Standard Brawl, etc).
*Pokemon Trainer enhancements
*Momentum conservation (could be applied to game speed section)
*No Auto Sweetspotting (this will be a tricky subject)
*Glitch, exploit removal (removal of infinite combos, triple jump glitch, etc)
*Character specific mods (be sure to note how our goal is to enhance each characters unique play styles. Only give a few examples of these mods with side by side video comparisons. Bowser's thick skin and Ivysaurs attack and razor leaf mods would be good ones to use).
Perhaps the end of the video should bring it all together by showing 30 seconds of really cool B+ gameplay.
This video should hold the dual purpose of showing people what Brawl+ is, and showing them how to play Brawl+.
I'd do it myself, but I lack the time or equipment necessary.
