A while ago I got a pre MM3 chip-modded SCPH-5501 PS1 from a seller on eBay to play burnt hacks and Japanese games, and while it loads games fine (unlike the previous 5501 they sent me), I've come to notice its performance is weaker.
For my most experienced examples, Silent Hill gets constant screen-tearing and Klonoa tends to slow down, which is how each game seems to respectively react to dropped frames. After watching videos, asking people, and most of all, testing Silent Hill (official NTSC-U disc unlike Klonoa) on my PS2, PS3 and unmodded PS1 without these issues, I can confirm these drops're happening way more often than they're supposed to.
How can I fix this (if I can)? It would seem there's a sloppy modding job at play, but I can't find anything online about modchips doing this.
