Oh Sears why did you do that?
Well that is a good chunk out of the font losing most of the lowercase and a bit of uppercase plus some useful symbols, that does put more burden on the GRAM to fill them in order to support the Sears Super Video Arcades(What a mouth full lol.). Damn what an annoying variable but I'm still glad you brought that to my attention so thank you. 
Meant that at the title screen. There are no "X presents" lines.
Oh, you mean the screen, I thought you meant from the GROM table.
Phew that's a relief. 
Well that is a different issue all together, that definitely puts a cramp into using the entire screen for text. It sounds like you have a better grasp on this issue, what do you think about it in terms of a work around that serves both the standard and Sears difference?
A fix? Like in this picture.

Like in modern games, there's mainly just the title and the copyright belonging to the creator. By overwriting the last two lines on the title screen ("COPR @ 1979" for example), there can be the full copyright spelling, the year, and on the last line, the full name of the company. Simple.
The grid is done in a format of
$200 + 19 (also example) for results, as stated on a
programming tutorial.
