Pokemon HeartGold - Infinite black screen when loading savegame

Shadark commented 3 years ago

Your console: Old 3DS XL Launch Method: Luma 10.2-bb07a73. Launching through TwilightMenu v17.0.0. Version used: Release v.035.s2. Game tested/used/applicable: Pokemon HeartGold [USA] - MD5 4fcded0e2713dc03929845de631d0932ea2b5a37

Expected Behavior: Game should work as usual. Actual Behavior: After starting the game, I can save the game. If I try to load that save, I get an "infinite" black screen, not allowing me to play the game. However, on a different Old 3DS XL the game works perfectly fine. I'm going to refer to the problematic device as "bad 3DS" and the other one as the "good 3DS". They are almost identical, bought years ago with 1 month of difference.

Also: I've disabled heap shrink option (both on and off), game is loading in DS mode. Haven't changed other options since the good 3DS is at default options for everything and seems to work just fine.

Other notes

I have a lotta notes.

Game + save works fine on a PC emulator.
Game + save works fine on the good 3DS.
The game was working fine till a few days ago, then stopped working on the bad 3DS, can't recall why. Afterwards I tried everything mentioned here, creating a new savegame, got a backup of the older game for later.
Reinstalling nds-bootstrap + TwilightMenu didn't work.
Deleting ramdump and/or _nds folder didn't work.
Downgrading to a older version of TwilightMenu and nds-bootstrap didn't work (the good 3DS is at TwilightMenu v16.6.0, nds-bootstrap at release v.035.1).
Editing the save (+ verifying checksums) on emulator/savegame editor doesn't seem to fix anything, save is fine though (checksums are verified).
Deleting the save + starting a new game doesn't allow to load afterwards, as I mentioned.
Putting a new/different savegame also doesn't work.
AP Patching the game manually also doesn't work (but works fine on the good 3DS).
Swapping SD cards between consoles and trying to load the save doesn't work on the bad 3DS, works fine on the good 3DS.
Other versions of the Pokemon HG ROM (don't have access to anything besides other untrusted dumps) behave similarly: they work fine on the good 3DS, they don't work on the bad 3DS (savegames seem compatible and they load just fine on the good 3DS).

Anything else I could try? I feel like I've run out of options and I don't know what else could I try, and it's apparently some issue related to the console/device and not to the installation, but since it doesn't seem to work at all... In any case, any help is appreciated and thanks for your time.

Have you tried the latest nightly version of nds-bootstrap?

Shadark commented 3 years ago

Just tried now with latest nightly versions of both nds-bootstrap and TwilightMenu (I know it shouldn't matter, but just in case), still not working.

RocketRobz commented 3 years ago

Try launching the ROM with a DS game in Slot-1.

Shadark commented 3 years ago

Tried both with and without a cartridge in Slot-1, no changes (with nightly version(s), still).

RocketRobz commented 3 years ago

Does this still occur on the latest nightly?

Closed due to no response, and for the reason stated in #1182
