This was a cheap and fast way to shortly release games.
Another problem came from the only 64ko Ram of the Plus standard : 464+ and GX4000.
As a result, implementing Plus features on existing games could be impossible without massive reprogramming if such games already used well the full 64Ko Ram.
Yet a 128Ko Ram would allows additions of Hard Sprites or DMA sounds more easily on a 64Ko ram using old game.
