i get this message
I saw something about that on wiibrew. Ill try later today. As for gdb did i miss installing something or do i have to set a path to gdb? I thought it was built into devkitpro.
Whoa that is super cool! I'm assuming a DSI exception is when I get a full black screen full of memory addresses which I presume is a stack trace or similar? I'll do some more research on that!
It should be in devkitPPC. In my installation (on macOS), it's in /opt/devkitpro/devkitPPC/bin and is called powerpc-eabi-gdb
@kaisersozeh to give you a clear answer, GDB is GNU Debugger. It's part of the GCC (GNU Compiler) package of tools. Debuggers let you inspect and manipulate memory, set breakpoints to stop at certain parts of the code, etc. However, when running on a separate machine, things get more tricky.kaisersozeh said:
Yes i found powerpc-eabi-gdb there as well. But the memory addresses didnt give me anything. With wiimpathys method above they showed up as ??. When i returned to coverflow it didnt crash right away but the box mesh for the covers on screen was messed up with a weird white triangle coming off the side of each cover. Oh well.The binaries are in "/devkitPro/devkitPPC/powerpc-eabi/bin".
The elf file has to be the same build as the dol that generated the exception in order for it to find the proper source location.
Sorry, I was away for a few days to go to my sister's memorial.
Yes it is. What i did was delete 3 wii pngs and there matching wfc files and the did ddownload missing covers and it downloaded the covers but upon going back to main screen the cover shapes were messed up and then it crashed.

(gdb)thanks for testing and the info. when i checked my code dump it only had 3 mem addresses and they all said - No line number information available for address with <strchr> something
u32 bufferSize = 0x280000; // Maximum download size 2 MB
u8 *buffer = (u8*)MEM2_alloc(bufferSize);
if(buffer == NULL)

}Awesome work!
