[Coco] Cartridge memory - mapping in and out

I'm a little confused...
If I load a cart with autostart disabled, then PEEKing memory from $C000
upwards does not return the cartridge contents. I can also read/write RAM at
However, EXEC 49152 ($C000) runs the game. Is the BASIC interpreter doing
something shifty here?
I have noticed that poking the GIME INIT0 register with a value other than
$7E briefly sets the register value, but on return to the BASIC prompt, it
is reset to $7E...
What I'm trying to do is map the cartridge ROM into coco3 memory space so I
can PEEK (and POKE) it from BASIC. Is this do-able???
