Bueno, aki os voy a decir como arreglar ese odioso problema xD
Algunas veces las Stages Hires se ven mas grandes de lño normal o el piso esta mas bajo como este ejm

Imagen Ejm: gracias a ALLANO del mugen foroactivo
Bueno, aki les doy los pasos
1º: Abre el Def de la Stage
2º: Encuentra esta parte del def [StageInfo]
3º Abajo de eso Agrega: hires = 1
Nota: Si se ven bien algunas stages Hires sin que salga hires = 1, no hagas nada; pero si tienes otras stages Hires que se ven mal borrales el hires = 1. (Esto sucedes en el Mugen Hires - no el Plus, Supongo)
