@jvhellraiser Try this nightly build.
The 0x023FC400 area is now empty.

That code writes a bunch of stuff to 0x023FC400 and then patches the game to execute it.
It doesn't work on nds-botstrap because that area of memory isn't empty like in flashcards and emulators.

(I don't guarantee it will work even if we found a good unused area in memory for the code to use)

Oooh wao this means we will never gonna be able to load this game on the twilight menu, I manage to load Dragon Quest IX - Sentinels of the Starry Skies using DS rom tool Integrated AP Patch Fix. and It loaded pretty nice no issues at all at least until now.

jvhellraiser on 14 Oct 2018

Never say never. ;)
I'm sure we can get this working.

Nope, it still seems to have something wrong there. Any code that uses that area still makes the game crash (I don't mean only golden sun)

piratesephiroth on 14 Oct 2018

No, it does nothing game + AP patch = Black screen
Now with Action Replay cheat for AP Fix = Black Screen , first i got a White Screen
RocketRobz you are into something the fix is there but you miss something.
can the code be injected and then be disable before the game notice it?

jvhellraiser on 15 Oct 2018

I still get a white screen all the same. I only get a black screen if I don't use the code.

(here's the confirmation that I'm using the proper boostrap, just renamed it to release)

I truly don't understand why is it that even with area 0x023FC400 being empty why is so hard to bypass this is it trying to write to another full area?

jvhellraiser on 15 Oct 2018

0x023FC400 is one of the areas reserved by the flashcards for their own patches, specifically for games with compressed arm9 binaries, so it is never touched otherwise.

nds-bootstrap clearly wasn't developed with that in mind and is using that space for something else.

piratesephiroth on 15 Oct 2018

i was wondering can nds-bootstrap imitate Bios or Twilight menu ++ (Imitate) maybe these games are asking for a bios check before they can load.

jvhellraiser on 16 Oct 2018

The original BIOSes are already in use in nds-bootstrap (except for DSiWarehax).

RocketRobz on 16 Oct 2018

thinking about could it be that the AP code use is wrong i mean maybe not in Emulators but in Twilight menu itself this exact code is not working.

jvhellraiser on 16 Oct 2018

It's a problem with nds-bootstrap, not with the code.
As I said, any AR code that uses that area of memory to write instructions causes the game to crash when it tries to run it, because nds-bootstrap is putting stuff there already.
It happens with any game.

Is this issue still present in the latest v0.12.3 (Rev 01) release?
I heard some changes were done to the reserved area mentioned previously (or something of the likes), so that got me thinking it Dark Dawn got fixed with one of those commits.
