Okay, as you say, there's clearly something there. It's moderately likely to be where the ROM lives on your machine. As a first tentative guess, I would start picking this apart assuming the CPU starts executing it at 2004a531. If you can dump the whole thing (you might be able to do binary search to figure out how large it is) someone can probably disassemble it. If you aren't up to converting it to binary, I could take a big blob of text capture from something like "e/l/p/n:3fff 20040000" (or whatever n: value gives you the correct amount for its size) and convert it to a binary file easily enough. I might even have the time to do some preliminary investigation, though I can't really promise anything there. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mouse at rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
