if it was compatible with emerald mine, it would need to be designed that way.rocksndiamonds is compatible with emerald mine
if it wasnt designed to play emerald mine, it wouldnt be compatible with it.rocksndiamonds was not designed to play emerald mine
it doesnt get compatible or get designed by chance.
it turns out that rocksndiamonds can not play even 1 emerald mine level.
all emerald mine levels (including the archive) are played by my software.
