Just a question... Are there any custom playables available for smbx 1.4.4? If you know any, please let me know and give me a link to the topic/download link
from what I know of, none have been made for 1.4.x yet. however, I think it's possible to find other playables in GFX Packs, or even some in 2.0, and put them in a 1.4.x episode (while also changing the hitbox, of course).
If you're looking for custom playables you should definitely look at using SMBX2 which already has a ton of new characters and the next release will include over 150 new NPCs
