Help Please - PS1 + Game Enhancer = Broken PS1?

[Jive3D]

OK here is what just happened. I got a PAL PS1 game. Tried to play it on my NTSC PS1 (old version, not the resized PSone). Obviously, normally this wouldnt work. But I have a 'Game Enhacer' that plugs into the I/O port on the back of the PS. I have used it in the past to play Japanese games, like when I imported Cowboy Bebop. So, the PAL game would still not load, I figured it was worth a try. So I checked out the Game enhancer instruction and it said press a certain button combo to switch to PAL. so i did that but the game wouldnt load. BUT NOW since I did that regular games wont load, even when the game enhancer is not plugged in. Then I realized that pressing this button combo doesnt allow for play of PAL games, it was switching the game enhancer for use on a PAL system. But now my PS1 wont play regular games, what gives? Is there a memory chip or battery in the PS1? Have I altered the bios somehow?

I have another Playstation, the resized PSone, but does this mean that my PS1 is screwed? ...ugh...
