Just started playing this romhack (v1.98b) yet again and I may have found a graphical glitch. Probably due to the dash feature.
Anyways, if you go all the way north in the town of Baron (not the Castle) right above the dancer in red, and you run left and right there (while holding the dash button) then the trees start to glitch out.
Not sure if this happens anywhere else, and I haven't tried on other emulators yet, but I thought I'd point it out.
Quite easy to replicate but I can provide a screenshot if needed.
I'm playing it on my SNES Classic by the way. Had to patch the ROM using something else than LunarIPS to get it to work on that.
