Lose the stick figure halo on the left of S, the line weight contrast is not visually interesting or sensical.
Use a different font for "sincade" the homemade mame font isn't good. Professional fonts are created with knowledge of the typographic arts. What you have is just a jumble of badly constructed characters, with improper kerning, line weight, etc.
Make the font in the center white with no outlines. Move it to the center, & make it more prominent.
Make the logos of the other companies outlines (if you must keep them.) I would also lose the "mame" logo, it's nothing special, and does not have make the same connection with people that might play your that the other logos have.
Lost the color in the right character. If you are going to use, color, use it somewhere else.
Maybe the characters in the center are part of your theme, but I would either get rid of them, or the other style characters. Right now, the 2 styles are not resolved at all.
That's my quick 2
