Help!! over stretched screen for one of my emulators

Okay so I've got a modded xbox i believe it's chipped. However im not sure
anyways ive got a problem that i believe would be "pint sized" to alot of you who know about modded xboxs.

I've got unleashx. and everything is fine except for my cps/cps2/neo geo emulator.

my cps(cps1) games run perfect! But when i try to run a game from the cps2 or neo geo list, theres a small problem: The game runs fine. and the sound is fine. but the screen is all fucked up. like i think it got over stretched somewhere along the line and the zoom messed up too.

* i just want to know if there's a way i can simply reset the screen settings, or put it back to default so i can play these games again. Cause i've been dealing with this problem for years. Just can't seem to find the guy who modded my xbox for me back when i was a youngster.

Please and Thank you!

I have no xbox experience re your question, but seeing as no one else is responding ill give you my educated guess. (educated as in common sense, i'm not looking up any of this crap seeing as i have no use for modding an xbox) also do u know u can play all those games on ur pc ?

the xbox has a HDD i assume, so if you don't have a data link to it from your pc, either from a cable or router. then I would assume you just have to remove the HDD put it in your pc, open the settings files you need to modifiy, then put it back in the xbox. (assuming the hack on the HDD gives No console interface directly from the xbox). i also assume, depending how the mod works I Dont Know, it may use a different file system than windows, or require another application to read the filesystem, or maybe linux could read it without issue. either way, sounds like even the basics are above your head. . . however if your motivated I'm sure u could do it, especially if theres a tutorial some were online.
