Console: DSi Device: SD Flashcard Model:

Compatibility: Unplayable

Notes:

Bugged items in the inventory (see picture) when it should be completely empty.

If you save and then load the game and then open inventory, things will be even more bugged. At first glance the black artifacts in the inventory screen (see picture), then the main character will be sort of offset in the game world, being able to clip into buildings and have very sped up walking.

Not fixed with manual JIT patches.

Wram icache enabled or disabled changes nothing.

The same save file generated with GBARunner3 works fine when used with mGBA.

Pictures:

Inventory after loading game:


Clipping and viewing the rightmost side of town on the left side area of the screen beyond the black border, and the main character being able to walk inside buildings:

Checked on latest dev commit and the item bug is fixed. Checked both with and without the above json file.

We can use the json file if it turns out to be necessary for DSes. For DSi there appears to be no need.
