which characters appear garbled? maybe the font itself doesn't support all existing characters (many fonts only support the most usual character set, and unsupported characters usually show as squares or rectangles)
No squares or rectangles. It seems if a game name has an apostrophe in it, the name becomes ineligible. So far, ES only seems to accept Opensans, so in the worst case scenario, you'll need to change "Conker's" to "Conkers".
I still have yet to see how the text fits when you show cover art, etc.
That I can't do until the metadata scraper is completed. I had to increase font size for the GCW-Zero, so hopefully the text isn't too big there, otherwise we may need to do some editing of the menu layout.
Quick Update: The garbled text for some game names looks better now that I removed the gray background on the game list screen. I have no idea why the background interfered, but it's better now. Games with apostrophes in the name still don't look perfect though.
