Load SNA from ROM to RAM on real hardware

Is it possible to load a SNA from ROM(Cartridge) without additional hardware? 

I know that it's possible e.g. with Dandanator or M4 but I was wondering if it would be possible to create Multi-game-Cartridges for a GX4000 where I don't have an expansion port.

So far I have only found stuff that needs some kind of hardware. Can you point me to a piece of software that is doing this?

i've done this before, "handcrafted"
all you need is a little free zone and a good cruncher
but i do not have (yet?) a generic program to manage this
i cannot promise for this week ;D

At least SymSnap only requires a ram expansion, nothing else:

So you could load 64K and 128K SNA files from floppy disc.
But I am not sure if this would help you in your case.

If there is also some source code available, that could help. I'm thinking about a ROM-to-RAM loader for a GX4000. Probably similar to what a Dandanator does. Of course that won't work for real cartridge games but all the converted games I guess could work. And having collections of 10-12 games on a cartridge would be really nice.
