In any other situation, I'd do just that. This particular project, unfortunately, is supposed to be a "vintage" port of an old game, and the original code isn't even mine. I would strongly prefer to emulate the "look and feel" as much as possible, as is typical of games. Is it at all possible to get CG to render it the old way, short of positioning every single glyph individually (which is a solution I'm ashamed to admit I'd consider if nothing else worked) or pre-rendering the text using SheepShaver where possible? -- Gwynne
