@Arisotura If it's not too much trouble, may I ask a few questions related to DS behavior during cold boot?
My emulated ARM7 is getting oddly chatty with the nonexistent game card, and I'm wondering if it thinks there's a game card there (and how to convince it there's not).
-
normally just returning blank cart data (all FF or 00) should be enough, if not you might have a CPU bug
On one hand I'm reluctant to suspect a CPU bug given that the ARM7 emulation I'm working with can handle both Linux and WinCE, but neither of those use Thumb mode. Since 0xFF is being returned for all cart data, could be a Thumb bug lurking.

It might also explain why the first time it tries to invoke halt mode, R12 has the wrong value, so it ends up trying to STRB into the firmware ROM area instead.

nah, that one also happens in melonDS, that's a bug in Nintendo's code.

yup, could quite be that. I don't remember in detail how the BIOS works in this regard.
