8MB ROM

Hi, I just reached the 4MB limit, the build is 4.12 MB, it works but the sprites upper the 4MB are not displayed,
is it possible to get it working on BlastEm ? something to change in SGDK init/build settings?
And will it be possible to get some 8MB flash card later ? can't find some
Sadly, banking is not a solution (single level / open world).
Cheers.

You can search for the details, but above 4mb is nonstandard and won't work with sega cd, 32x, and some clones. Retrostage has SSF2 mapper-capable boards.

Thanks, yes its a hard decision.
Played a bit with banking, didnt know it was kind of automatic with sgdk (it is manual on gbdk, had to handle bank switch in the music player).
Just saw the sega blaster, thought it would be more expensive.
But to get it working on a pure stock 4MB would be cool as well..
Cheers.
