Pete is porting Frodo, a free Commodore 64 emulator, to Microsoft’s Flash-imitator Silverlight. Frodo is originally written in C and uses pointers extensively. Silverlight doesn’t allow pointers, so Pete demonstrates how to emulate them.
Simulating pointers in pointer-free sandboxed platforms is a bit unorthodox, but can make translating code easier…This isn’t something you’re likely to need to do in your own code, but it an interesting exercise in any case.
