I THINK I came up with that one, but TBH I wouldn’t be surprised it if was known before me. IIRC I posted it back when I was searching for unblockables on Ken.
Anyways, you can do fj.HP in the LEFT corner on some characters and depending just on when you hit the button in the air it will either land in the front or in the back. I dunno who all it works on. Some of them it works on hit only some on block only.
Also one setup I like (but it isn’t a meaty setup so watch for reversals.), LK Ruffian - back dash - fj.MK will still hit as crossup. But people will think its not because of the back dash and it’s not a deep crossup. Also, after any Criminal Upper walk forward 1 step - jumping MK - not a crossup. Walk forward 1 1/2 half step (basically ~3-4F more at most.) IS a crossup. Don’t walk forward jump is a 5F safe jump if they quick rise reversal.
