Heh, that's very true. Nearly everything I know about how to hack and reverse engineer software comes from my experiences programming. The problem with applying that methodology to hardware however, is that it can get a bit expensive.
Wow, those are some remarkably simple tools. Sometimes...
Like I said, I'm still a noob at this kind of stuff, but I basically get the picture. I just wanted to make sure nothing was going on in my examples that defied my current knowledge of electronics. I didn't really think overriding a chip would ever be as easy as putting one chip on top of...
I'm not sure, but http://www.dms3.com/dms4ezi/downloads/Installation_Manual/DMS4_EZI_Installation_v1.4.pdf modchip appears to be overriding the BIOS with nothing but connectors on the chip's pins. How might that work in theory? I suppose this doesn't have much to do with the original question...
Ok, so what about modchips, which override signals by only soldering to various points on the PCB. How do those work without having to cut connections?
Edit: I see what you mean with the BIOS chip. I didn't look at that one closely, just pulled it out because I happened to remember it as it...
Hmm... But then, why is it that the chip soldered on the top ends up being the one the data is read from and not the one underneath that you soldered over?
Well, that much makes sense. But is there any way you can think of to get rid of the other clock signal without cutting the connection?
This is probably a complete noob question, but due to my general lack of experience in this area I wasn't able to find the answer on my own. When you want to reroute a signal on the PCB to an external location, or replace a signal with one of your own, what situations do you need to cut the...
