This was a "good" other way to get rid of Attributes Clashes and having actual "colours" on ZX Spectrum. But some speccy ports were then emulating the attribute system, which can be quite bad because CPC in Mode1 has half the colours the Speccy has.
*'''R-Type''' : the background has a smooth scrolling while the sprites are fixed character grid based. The engine was keepted in R-Type128 modern remake.
*'''Space gun''': this game was even released for Amstrad PLUS... Although coming very late in the CPC era is not really good and was probably rushed to the release.
