Question about the GX4000 Acid chip

[dcdrac]

Is it possible to strip the code from an acid chip so you can have it along side an extracted bin file from a Cartridge, and have them saved onto a floppy?

The Acid chip is not a rom with code in it. Have you read the Acid wiki page - Amstrad Cartridge Identification Device - CPCWiki ?

The program in a cartridge does not interact with the acid chip so you could copy a program to disk, although I do not know what changes may need to be made to make the program run in ram instead of rom.
The acid chip is only there to authorise the plus/GX4000 to execute the program.

The ACID is actually there to make the CPC run at all. Without the ACID chip nothing will work, not even the BASIC prompt would appear.

I think you are asking:

I want to play cartridge games transferred to disc? Correct?

The problem is these games are written to run from cartridge.

It may be possible to transfer some of them to disc and patch them to work but nobody tried that.

Totally correct

That's what I said, without the acid chip the cartridge software will not run, Basic has the acid chip so it will run.

Any way of fitting the acid somewhere in the CPC and therby circumventing this problem? Though I'm sure if it were that easy someone would have done it by now.

I haven't tested it yet, but I believe it should be possible to play plus cartridges if you have a ctc-ay and a developer cart.

As you've guessed, it is that easy and it has already been done: AcidInside - CPCWiki
