== French Way==
Many French games were designed to have common graphics with their [[Thomson Computer ]] Computers versions.
The TO8 and latters models did have the same Video modes as the Amstrad Plus (minus the hardwired Extra plus features, yet the 4096 palettes and the 3 modes were there) but also could display an extra character attributed mode (320x200 in 16 attributed colours, like a better Speccy).
*Bivouac / chamonix challence from infogrames also had a TO8 version with almost exact same graphics as Amstrad's.
It is to notice that as TO8 featured a 4096 colours palette and the same resolutions/Video modes as CPC, the French developpers already had the experience when dealing with Amstrad Plus extended palette.
As a result, if upgrading those games for the Amstrad Plus, just getting the exact same graphics as the TO8's counterpart would be enough. Also some Games were largely inspired from [[Atari ]] ST version, concerning graphics, as the 16 colours mode in Atari ST has the same resolution as the Amstrad Mode1 (320x200). As a result, many french games in Mode1 are graphically Atari ST ported.
The same is quite true with IBM&compatible PC in CGA mode, being basically a limited in palette Amstrad CPC Mode1. So Games maker could fit their Graphics into PC (CGA or even EGA), Amstrad CPC and Thomson range (TO8, MO6...)
Examples :
*Jim PowersPower - In Mutant Planet by Loriciels (1992)
*l'aigle d'Or 2
On the other hand OCEAN managed a lot of good stuff despite using Speccy/Amstrad crossdev.
Advantages were the shared Z80 CPU and also the AY sopundchip soundchip (with latter speccy 128), and the fact Amstrad Mode1 was somewhat nearly compatible with speccy graphics.
