First I want to say thanks Achilles, this is great. I use Dolphin, so if it doesn't work that's fine. But whenever I try to turn on hurtboxes, it forces the spacy to shffl dair. I think its because the code for hurtboxes is the same as the up throw up air fox one? Tried spoofing a 3rd port controller but it didn't work, both spacys, etc. Also, why does the subaction display show decimals for some moves? Thanks in advance!
I know it's been a couple weeks, so maybe you've figured it out already, but I don't think this has been answered so I'll take a stab.
It sounds like you have the DBLEVEL set to Develop, which turns on the normal debug controls as well. He mentioned in the OP that this can interfere with the ones in the pack.
There are two workarounds to this. Specifically, using the built-in 20XX toggles for collision bubbles (Y+Right does it for all characters), which will simultaneously revert you to default size via the debug control (which isn't a problem).
Alternatively, you could use the debug control for collision bubbles (which is what you're currently doing) and just press L+R+Down or L+R+Up afterward depending on whether you wanted P2 to attack at you normally or just stand there (with L+R+Up you'll have to wait 3 seconds without pressing anything if you want P2 to just stand there).
Someone else might be able to answer the decimal frames question better than me. However, my initial observation was that it occurred when I l-canceled, so a guess could be that it happens when your character is performing an action at a faster speed than normal.
