Screen problem help please

[DTST]

Long story short when launching with Riivolution the screen is cut at the bottom a bit so it doesn't show the battle names and only shows half the battle portraits if you look at Mastaklo's older videos like this one

Peach's Castle N64 [SSBB Hack]

and this one Knuckles is ready to Brawl [SSBB Hack]

i have the exact same problem.
