Another problem came from the fact that both the 464Plus and GX4000 (essentially a cut down 464Plus) had 64KB ram. As a result using the Plus features to the full was not so simple if the game was to run on these systems. If 128KB ram was the minimum then this would have allowed more flexibility for graphical data, sampled sound etc and would have easily enhanced a 64KB only game.
A 6128PLUS config with 512K ROM cartridge and disk Drive support is the optimum PLUS config, but such beast was never fully unleashed yet.
