I get the error partway through in game and I have not played Pokemon Pure Heart on Emulator on my PC. I can't say where I get ROMS from.It means something's messed up.
When does this error occur? Do you see it when you start the game, or partway through?
Where did you get the ROMs from? Did you patch them yourself? Do they run correctly in an emulator on your PC?
That wasn't the question. If the game crashes in an emulator on your PC, then that would indicate that there's a problem with the ROM and that it is pointless to look for a problem on your 3DS or with TWiLight Menu.I have not played Pokemon Pure Heart on Emulator on my PC.
I'm going to try that.hmmm it may be the emulator try using a nds forwarder to turn it into an app on your 3ds
if that doesn't work try a different emulator
nds forwader link: https://wiki.ds-homebrew.com/ds-index/forwarders
If it doesn't work in TWiLight Menu, it is unlikely to work differently when run using a forwarder. Those are just different ways of accessing nds-bootstrap.hmmm it may be the emulator try using a nds forwarder to turn it into an app on your 3ds
There is no other way of running DS games on a 3DS without using nds-bootstrap.if that doesn't work try a different emulator
As this is a romhack, there is nothing to dump.first instead of using the nds original file dump it in godmode nine
No, that is from seven years ago and has been entirely superseded by TWiLight Menu and nds-bootstrap.ok here is the back up plan lol

I for one have no idea what you are referring to. Do you have a link with more information about this error?romhacks can run on there own error 001200930-00019222102 could occur but no biggy
But those numbers do not appear in the screenshot provided, so how are you arriving at that conclusion..?i think its causing this problem

it's most likely an AP Error as True Soul and Pure Heart are fairly new rom hacks that probably won't be finished as the creator himself has lost interestA moment of further searching suggests that this game is known to have problems with TWiLight Menu, possibly due to AP measures.

If that is the case, then you can try making sure you are running the latest version of TWiLight Menu. If that doesn't help then there is probably nothing you can do except wait for either TWiLight Menu or the hack to be updated.
Googling to see if there are similar problems with Soothing Silver is left as an exercise.
