I just added a very short and simple article,  Modifying bootloader-compatible C18 code for MPLAB SIM simulator.  It came to my attention last night that it was impossible to use MPLAB SIM to simulate code that I was working on, which had been developed with the modified linker script and remapped vectors to be used with the USB bootloader.  One simple modification fixes this, but being my first time working with the simulator it took some head-scratching to figure it out, so I wanted to put it together into a basic article in case someone has the same problem in the future.

I'm working on expanding the 18F4550 USB Interface article into a standalone tutorial, so stay tuned for that.
