Hiya, first time poster, long time lurker and I'm already here with an extremely specific question. Basically, I've just set up my very first OG Xbox with Cerbios and everything and I'm really happy about that but I WANT MORE. I realized that there aren't any trainers for some of the games I'm planning to play so I wanted to set up a debug environment so I can do some reversing and patching of the executables myself. Don't worry, I have a lot of experience doing this with other consoles, so it's not like I'm completely lost. My plan was to set up a dev environment on that xbox using the Easy XDK Installer, along with setting up a WinXP VM on my PC with Visual Studio 2003 and everything. Finally, I expected to be able to attach VS2003 to any process that's running on the Xbox, find where a certain games stores e.g. the current amount of money, set a data breakpoint on that address and then figure out how to patch the executable so that I would have infinite money. Surprisingly, a lot of this has worked very easily. The setup was done in under two hours and I have already identified an interesting address in one game. However, I can't seem to seta data breakpoint on that address, as VS2003 always tells me "Invalid context". Has anyone done something like this before? Do you know how to setup a data breakpoint? As far as I can tell the problem is that VS2003 expects me to set the data breakpoint on a variable. Obviously I don't have the source code so I can't work with any actual variables. Is there a workaround? This may be a stretch, but is it really not possible to just attach GDB remotely? I'm not planning on doing any actual software development, I'm really just interested in reverse engineering. Any help would be very appreciated, thank you!
