melonDS Some DSiWare freezes on boot

Native (i.e. not 3DS) USA versions tested, on a USA NAND, imported using the new title manager. Running from DSi menu.

Looksley's Line Up (log)
Nintendo DSi Instrument Tuner. Gets past ESRB screen, but then freezes. (log)
Thorium Wars. DSi's own user-facing "An error has occurred" screen appears. (log)

edit: nice work on the title manager btw

Gold Fever (USA) freezes on boot, but works fine in No$gba v3.0.5 off of the same NAND. Tested with interpreter CPU and revision https://github.com/Arisotura/melonDS/commit/879695070a728c589d6999fe40799b01d34c35af, all the other games I have on the same NAND at least booted to the title screen (about a dozen DSiWare games, all of them USA region). This might make Gold Fever a useful debugging target. Log attached. log.txt

oh, interesting, it's using the GXFIFO mode of NDMA. I will need to look into how the 112-word limit thing interacts with block subdivision, eventually, but I think I can make a guess.

latest revision will fix Gold Fever.

as for the list in the first post: the first two titles need DSP support. Thorium Wars, however, is looking interesting.

Is DSP not already handled by teakra?

Thorium Wars(US version) imports and runs fine for me.

Looksley's Line Up and Nintendo DSi Instrument Tuner still appears to not boot (74f479c). The ARM9 gets stuck waiting for the DSP status to indicate the read FIFO is not empty.

(loop repeating forever; Nintendo DSi Instrument Tuner has the exact same loop at 0x0216DE98, presumingly this is some SDK code?)

Looksley's Line Up (USA) shows a few initial screens now, but apparently cannot start a New Game.

Looksley's Line Up and Thorium Wars get in-game now and may be playable. Nintendo DSi Instrument Tuner still freezes.
