Did the nightly build work with that game before that specific commit?

[hkzorman]

I just tried the nightly build, to make sure I didn't reported a bug already fixed. Before that I have been using release build (Release v0.35.s5). Neither has worked for me.

[Peter0x44]

According to the compatibility list, it should work. It was tested on nds-bootstrap 0.21.2, so try that version and see if anything changes

[SimPiko]

Last time I've tried that game, I had to set 'Heap Shrink' to 'Off' to boot it, but that was with latest official nds-bootstrap release (0.35.s5).
edit: sorry, forgot to write that I only have DSi XL. Not sure if that will help on 2ds

[Squall-Leonhart]

Confirmed, I'm not 100% but it seems to be the same issue affecting Phantom Hourglass (AZEE) on the 3DS/2DS

I don't think the heap size controls are actually working, otherwise they just don't affect these 2.

I'm targetting the testing of a few more games <64MB because afaik the only real difference with PH AZEP is languages making the cart size larger (and AZEP works trimmed to 68MB or full size)

[hkzorman]

Using the latest nightly, I confirm that turning off heap shrink works.
Heap shrink was set to Auto before. Is there a way to make it off by default on this game, so future people don't get this issue?

Thanks for your help by the way!

[NightScript370]

This can be done in a future TWiLight Menu++ update
