    Nice. I am not sure how personally useful I will find the DSi stuff but I am certainly happy to see it for others. If it also means the debugger is being tweaked and improved then even better.

    Nice, but there are still a lot of bugs with no$gba that I would like to see fixed. For example:
    - Exceptions are not correctly emulated. When nintendo's custom exception handler address is zero it does not even jump to the exception vector, even if this exception vector was overwritten on the arm9 (by setting it's address to 0 instead of the bios and putting your own code in there)
    - There are still issues with the 3d engine sometimes (seem to be some kind of sorting problems), mainly with an orthographic projection. There is also some texure distortion sometimes (only at some angles). (and it still has no anti-aliasing, but that's not really a problem, would be a nice addition though)
    - When the DTCM is not mapped at nintendo's default address, it's impossible to view it, because in the memory viewer it's zero filled (devkitpro maps it to 0B000000 for example)
    - Setting a breakpoint at a thumb instruction while in arm mode fucks everything up (and the other way around)

    Mainly that last point is very annoying.

    @nocash123 I've got to ask... are you describing a mere bug or an exploitable vulnerability here? I'd be interested in developing this into something end-user-friendly if it's the latter!

    Just a bugfix for the AES hardware emulation, needed to boot the "System Flaw" game cartridge via the firmware's "System Menu", nothing exploitable.
