i bought me the game GISH and installed on my MacMini with morphOS 2.7

The game works, but the Fonts (ingame and menus) are not visible. I see only white boxes, so it isnt possible to navigate in the menu and chance game settings.

Did you check with Scout is there any font missing in your system?

Wouldn't it be fairly easy to implement a wrapper such that if a program requests/requires the use of a font which is not present, it defaults to - eg - system font?

Not going to work well in all cases (eg for symbol, dingbats, etc) but would be better than displaying nothing.
