more looking at dead games, or in this case a dead sdk
at least from the description marmalade sounds kind of cool. it was essentially a standardised runtime environment (write once run anywhere) for C++ and Objective C with platform non-specific APIs for accessing most features. and for shit's sake it had it's own fucking binary format and loader, which seems cool and similar to an idea i've had for a while.
not done full research on this yet so can't say much more
