Hi!
Only very few games can be promoted to a GFX Card Screen (which can be done using a utility like NewMode). The reason is that many do not use the API of the OS (like "OpenScreen" and such to open a display) but instead directly hack the chipset hardware. Most modern games support GFX Cards, though (or are sometimes even GFX Card only...), and a few old ones (the old game "Legend of Faerghail", for example

). But most old games won't run on GFX Board, taking asides running them on GFX Board using UAE...
