I've had a report that fast firmware downloading doesn't work with the latest release of BricxCC (either tower). In my tests, with an RCX 1.0 brick plugged in, low ambient light, short distances from the USB tower, and all the firmwares I have (...) (21 years ago, 3-Nov-03, to lugnet.robotics.rcx)

I've been having some trouble with the 0.2.6.10 brickos kernel compiled with gcc 3.3.2. Whenever I try to use the dsound_play or sound_system functions, the kernel crashes immediately.
