Changes

The practise many of some GX4000 cartrige cartridge game developpers had developers was to directly put an almost unchanged Game form game from the CPC OLD library into a Cartridgecartridge for the Plus/GX4000.

Some time times such games even had to be lighted from some features (graphical page) removed as the 128Ko 128KB only Cartridge was a bit short of Bytes cartridge had less capacity compared to a 3" Diskdisk (178K with standard DATA format, later disc games used around 210K on each disc).

Of course this didn't helped help the [[Plus]] range at all and was almost as shamefull shameful as the [[Speccy Port]] technictechnique.

This was a cheap and fast way to shortly quickly release games.

Another problem came from the only 64ko Ram of fact that both the Plus standard : 464+ and GX4000had 64KB ram. As a result using the Plus features to the full was not so simple if the game was to run on these systems. If 128KB ram was the minimum then this would have allowed additions of more graphical data, sampled sound using the DMA sound, and would have easily enhanced a 64KB only game.

As a result, implementing Plus features on existing games could be impossible without massive reprogramming if such games already used well the full 64Ko Ram. Yet a 128Ko Ram would allows additions Examples of Hard Sprites or DMA sounds more easily on a 64Ko ram using old game.   Most Cartridge games were "Almost Direct Disk to Cartridge Port" as some few extra PLUS features where still implemented :*[[Batman (Cartridge)]]*[[Barbarian 2 (Cartridge)]]*[[Mystical (Cartridge))]

But it This was better than nothing.  Most of those games were known as good games ond the CPC Old. The bet was that it would still make good games on [[Plus]] standard. Yet peoples saw no interest to buy an expensive Cartridge with so few adventages, as they often had the Cracked Disk version. Most games with OLD and PLUS version are "Almost Direct Disk to Cartridge Port". Yet the Extra PLUS feature could vary a lotdirect ports.

Batman and Barbarian 2 Yet people were not interested in buying an expensive cartridge with no or few advantages when the CPC version could have make great use of 2 button padles be bought and a 4096 colour paletteplayed on the Plus.(Cartridge games were sold at £39.99, while disc versions were normally £15.99 and tape version was £11.99)

It is nowadays a common feature to modify existing Old CPC games into "Almost Direct Disk to Cartridge Port", just by modifying the Colours colours palette to match the [[Plus]] capability.

As most cartridges were the original Games release from the GX4000 era, it was mostly applied to games, yet the crack of the ACID chip and production of modern era Cartridges (or multi-ROM cartridges) may lead to Direct Disk to Cartridge Port applied to any knid kind of softwaressoftware.
