Is there a way I can get a debug log from my app while it is running? I tried writing a log file out using FAT while running under desmume and I discovered it doesn't actually write to disk, it just "virtually" writes to disk and keeps it in memory. :-(

If you use no$gba (not the freeware version), it creates DEBUGMSG.TXT in the directory where no$gba.exe is located. This file contains user-debug messages as well as 3d and wifi logs.

Desmume works together with GDB for debugging code.

I heard about the special version of no$gba. I'll have to try that out. I know that desmume works with GDB, but I don't know how I would send a log message to GDB. How do you do that? I am new to gdb.

Wow, $1700 for the version of no$gba that supports source-level debugging. Hmm..... Does the $15 version allow me to write a debug log? There's no mention of logging on the web site http://nocash.emubase.de/gba-dev.htm so I'm unclear. $1700 is a big much for free game development. $15 is probably too low actually. :) Well, I guess I can try the $15 version and see if it does anything. That's not too much to "donate" to the no$gba project.

You want custom debug messages from an emulator? Even if the emulator doesn't support this natively, you could just fill some memory region with your current debug contents.. and have a seperate application snoop the memory of the emulator, and extract it that way. (Look into attaching to processes and reading memory from other processes .. Linux has a ptrace interface)

Given, that in this case you got to do several address translations (from NDS app to emulator memory location to mapped process memory) i really wouldn't recomment this approch to anyone (even if you know what you are doing)
But using the build-in memory, code, register, etc viewers might be helpfull.

The NDS has 2 screens...so just use one as a debug messages terminal...I use this for my apps...
