A Speccy Port or Spectrum port is the name given to a game which has been converted directly from the Sinclair Spectrum with little or no changes to the Amstrad CPC. Often the Amstrad version ended up fairing worse than the original Spectrum version.
Why ?
The ZX Spectrum shared the same CPU as the Amstrad and had a simple graphics display. The Spectrum was very popular with the Amstrad having much less market share.
To "gain" time and money, the Spectrum code was re-used.
The Amstrad screen was reduced in size to match the Spectrums and often most of the colour was removed. Most spectrum ports were done in Video Mode 1 (4 colour mode), because the resolution of this mode matched the resolution of the Spectrum, and this allowed the use of the same graphics.
Speccy port was also seen on the MSX and Enterprise.
Some games actually ended up pretty decent.
But so many of them got theyr graphic totally unchanged, displaying some kind of colour attributes "artefacts", proof of the faulty portage.
A typical Spectrum port to the Amstrad is said to have been done in 3 days.
It is not known if they lacked the knowledge or will to develop a better CPC version, or simply didn't have the tools to do so.
Often an Atari ST was used for Cross Development.
Consequences
The Amstrad CPC was one of the best 8 bit computer of his time in term of graphical capabilities. But this had a price...well, a weight in term of CPU ressources.
As so many games were ported from the "inferior" Spectrum, the Amstrad range could hardly benefit from his main advantage.
As a result, so many games were slowler, painfully animated, with a bad gameplay...AND had bad graphics too.
C64 had better sounds, scrollings and Sprites capabilities. Spectrum had less power taken by Video RAM, so could handlle animation or scrolling more easily.
Amstrad had to be specifically programmed in order to get good animations. Yet Speccy ports weren't programmed in such way.
As a result, most Speccy and C64 fans rarely give Amstrad the credit it deserves.
Exemples
- PacMania
Typical exemple, yet it managed to be a nice game despite this.
The title screen and HUD show the attributes and were almost completly unchanged, yet with less colours on screen than the Speccy version.
Ironically, the game manages to display 6 colours in the 4 colours Mode1... Yet the game's area remains completely monocolour (coded in 1 bit) and "colour attributes artefacts" are still present..
