That was fast, man !

Regarding the build: You can just copy&paste from any existing driver.
There's nothing target-specific in there at all.

Regarding the usage: You can try samples\multidemo. Put the main
binary, the four overlay files and your .emd file onto a (virtual)

Maybe you can/want to do the same done with Atari TGI drivers: Some
core code re-used to build a whole bunch of .tgi files...

Although not strictly necessary to is always desirable that the driver
can detect if the RAM in question is actually available - and fail to
initialize if not. Then it can be used like in multidemo which tries
to load several drivers until one loads successfully.
