Look at the source code to ION, it's really complitcated because it needs to 
be installed.

When you program for a shell you get shell features like:
* relocation (program always runs from same place)
* writeback (save high scores inside program!)
* libraries (nice routines like ionFastCopy, ionPutSprite...)
* run it from a nice menu!

Without a shell you must write those things and a loader and everything.

MirageOS can run almost all ION programs, but only if they begin with ret?  
(someone should fix that bug and allow XOR A programs to run!)

Shells have to do stuff that involves copying a small loader module to free 
ram and load programs and back again...

You could always look at the source code to IceClimb, my second game.
