Which game are you having trouble seeing text in?
I had this problem with Dead Rising, turns out that game is designed for HD so on SD it has barely readable text. This is on purpose to force people to blow thier money on a new TV. There's no good reason why games can't play normally on SDTV. It's a scam and these companies should be ashamed of themselves.

The only way I can think of solving your problem is buying a used wireless adapter off Ebay or something. I'm guessing it won't be cheap but it will be less than 100$. Also buying used electronics isn't usually a good idea.

Btw why won't your parents allow you to get a longer cord? Tell them you'll secure it to the baseboards and make sure it's not in the way/an eye sore.
I hear it's better to have a wired connection since wireless can have lag spikes. I play on wireless but my router is like 2 feet from my 360. Not sure if that even matters but I don't see much lag.
