I've have a problem with many of the Retro Classix in general. I haven't found a way to disable what looks like bilinear, or linear filtering in the games. I only have this problem with GOG games in certain collections, I couldn't get dgVoodoo to work either, even though that worked with a Steam Data East game from G-Mode, possibly unrelated, but I've noticed this seems to be true with Piko games from GOG, Steam Piko games can start with the bilinear/linear filtering off. I would rather see razor sharp pixels than the blurring effect in these games, we need a way to disable it please
