I'm using the OAK chipset GDD atm, if that makes any difference?

The situation with the opened lid I was very surprised, apparently bypassing the system call it is verified elsewhere.
It's very strange. But in my tests, did not notice anything like that.

Great, that's what I was thinking - I haven't seen a game yet which wants to read in 2532 byte sector mode?

Games never read these data directly, they ask subheaders through separate system calls.

Yes. But for best result, put DS resources to HDD/SD, the core scans all devices and partitions, so you can boot core from CD, but resources can be loaded from HDD/SD.
Or you can use boot loader on CD for load core from any devices.

I make new bios for boot loader with switching, test it: http://www.dc-swat.ru/download/dc/ds/4.0..._switch.7z
