		Enhanced standard NXT firmware
Over the past couple days I have used the IAR Embedded Workbench to implement some enhancements and bug fixes for the standard NXT firmware. The bug fixes are as follows: 1. RIC drawing code incorrectly checked the size of the OP_LINE structure for (...) (18 years ago, 16-Mar-07, to lugnet.robotics.nxt.nxthacking, lugnet.robotics, lugnet.robotics.nxt)
