> How I can extract the partition image with chdman ?

Please be aware that even if you can extract the low-level image with chdman, you're still going to need some way to mount it as a virtual filesystem.

Be equally aware that not every game has what modern operating systems think of as a filesystem, nor drivers to interpret it.

Last but not least, just like any game that's released on any platform, the game itself is ultimately driven by some sort of game engine. That game engine might have any number of methods for loading model data, processing it, and turning it into commands that result in something being visible on-screen.

What I'm getting at here is that, yes, you can extract the low-level system image using chdman. But that's one of about fifty million steps that you're going to have to go through, only one of which we can help you with, that will contribute towards your goal.

Emulating a given platform doesn't typically require intimate knowledge of how a particular game stored its models, or its textures, or really any other sort of data. It just involves running the CPU code that comprises the game engine. That same CPU, and same emulator, could run database software, a word processor, or a flight simulator if the underlying binaries happened to tell it to do so. The emulator doesn't care about the actual task that the emulated machine is doing, and so it lacks that knowledge.
