Metal slug X looks like crap

[Azel]

I am new here and i have recently installed retropie 4.4 on my raspberry pi 3 model B (not b+). I put metal slug x on it and it has a lot of graphical glitches. Can anyone help me? The micro sd is a pny 32gb card. I use a ps4 controller with a usb cable.

@azel Can you share a screenshot or describe what glitches are you noticing ?

I tested an snes game (mortal kombat 3 ultimate) and it runs perfectly

@azel SNES games use a different emulator, so there's no comparison here. What emulator are you using for the game ? It's not quite clear from the video if you're using fbalpha or pifba. The glitches you're seeing - from the video - look like some sort of shader is running, but that does not seem to be the case on the start screen.
Are you using the stock RetroPie installation or a 3rd party image ?

@mitu i use Final Burn Alpha.
