ZX Spectrum

LED Storm

The monochrome Spectrum version suffers from the disability to scroll diagonally, although it does manage parallax. This problem is overcome by shifting the course sideways in large chunks, so keeping to the roadway is tricky at the best of times - especially considering the small screen size - which becomes annoying after a while. This artificially-imposed difficulty level plus other faults, such as becoming 'attached' to the kerbs, makes this the only version to steer clear of.
