Changes
This page aim to cover the historical aspect of games crossdev from the commercial era.
* Straight portage : one version was first and specifically designed, then it was slightly adapted to match the new machine (speccy ports, often)
*[[Zombi]] from UbiSoft was first released on Amstrad CPC, then ported on different computers follonwing its success.
*Head over Heels : may be considered as such as the Amstrad version is the only to be actually well redone graphically while the Speccy and C64 are both Monocoloured (except the HUD), thus being sort of the reference.
Yet such occurance was quite rare as Amstrad CPC wasn't really the leader computer, exept perhaps in France.
Such project were often done by serious games company and every versions of the game were often close to each other.
*Rick dangerous : Amstrad version includes aspects of the Speccy version (Z80 codes) and C64 version (graphics) and has stuff of its own (Graphics too).
==C64 case== A few games share the same pseudo Mode0 graphics with the C64 version. *IK+ is perhaps the most notable example. *Barbarian (beheading one) too. In those case, tha amstrad often performed well Graphically thank to a somewhat better palette but the greys. Concerning sounds and Speed/animation, this is another story. Yet often C64 used to get a completely different version than the Z80 based Speccy and Amstrad. == French Way== Many French games were designed to have common graphics with their Thomson Computer 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). As a result, the Graphics development could really be used with exactly the same pixels unchanged on 2 computers, explaining how the french managed to well use Amstrad graphical specifications. Examples :
*Mach 3 from loriciel(s).
*Bivouac / chamonix challence from infogrames also had a TO8 version with almost exact same graphics as Amstrad's.
Examples : *Skate ball: mode 1 4 colour . *Night hunter *Iron Lord Mode 0 graphics same could also be largely Atari ST inspired as both used 16 colours Atari St graphics thanks and hardwares existed to the same resolutiontransfer Data from one to another. Examples : *Jim Powers
*l'aigle d'Or 2
==English way : Speccy Ports==
*Lazy : almost ran untouched on a CPC.
*Good : It was really cross-developped and the Amstrad version is well enough implemented despite sharing stuff with Speccy one.
On the other hand OCEAN managed a lot of good stuff despite using Speccy/Amstrad crossdev. ==Spanish Way== Perhap a spanish may give us more details ? Seems that España's market featured Speccies, MSX and Amstrad alongside, all Z80 based. What about this then ? Nowadays Spanish Games developpers use to crossdev games in Speccy, MSX and Amstrad. ==16 bitTools==
Atari ST was used to develop games for CPC.
Raphael Cecco, creator of Exolon or Cybernoid series was known for programming on Atari ST then channel codes into the CPC (he said this in interviews).
Also Loriciel developped Hardware tools for such 16bit-computer helped developments., as seen on this picture :
