Thanks! I got a bit busy lately and I don't expect to have too much time since I'm moving to another country soon. Hopefully I find some time to write a more in-depth article on some inner black magic of various peripherals. I think the NAND storage is particularly interesting.

Regarding the progress of the current iPod Touch 1G emulator: I'm currently stuck on a nasty bug where a piece of memory seems to be mapped incorrectly and the emulator crashes when trying to render the keyboard. I'm still not entirely sure where this originates from though.
