Extreme slowdown on Ace Combat 3 both US and Japanese Translation

I get extreme unplayable slowdown on both versions, the PAL version seems to run fine. The games seems responsive playing sounds when I press the buttons, I even died once but the screen FPS drops almost to zero. On the Japanese version I can't even get to the start menu as the lag starts on the cutscenes.

I have an HMD Skyline and running on the default settings. I tried changing the renderer to no avail.

I am not tech savvy enough to really know about any other settings and a google search has yielded no result as I seem to be alone in this.

I seem to run most PS2 games without issue so I have no idea what is doing this.

Any help is appreciated! Thank you!
