I've always used Glyph Designer with no issues to create bitmap fonts, but I've just tried creating a font with it and I can't get it to display within my sparrow game. I've done all the things I usually do, import it inside game.m, and then set it up as I did before, but it's not appearing. I've looked at the older .fnt files and the new version and the only difference I can see is that the new version has a bit extra at the top, but even removing that doesn't make it work.
It's probably something obvious I've missed but I thought I'd better mention it incase the new .fnt file is not compatible anymore.
