Fix fall_back.gb's title

Currently 0x134-0x142 consists of FF but 0x143 is 00. This results in question marks being printed as the title.

I will not be creating a PR addressing this as I'm not sure how you would want this handled, but my proposed fix is to either set the aforementioned range to 00's or give it a proper name (I have been using `Test GameLongNam` as it reaches the character limit of 16 and has a space).
