Would be possible to send a irq from ARM7 to ARM9 and use existent myIrqHandlerIPC in arm9/source/cardengine.c to catch it, and then, perform the swap?
For now, it's the "easiest" solution I have found
Edit: I have tried with following function:
i2cWriteRegister(0x4A,0x11,(i2cReadRegister(0x4A, 0x11)^0x80));
but it's impossible to swap from ARM7

Yes, that can be done.@Robz8

Hello again.
I haven't completely understand IPC and sharedAddress variable, so I suppose that my solution could be wrong. Could you please check why it doesn't works? Thx!
Those are ARM7 cardengine.c new lines (inside void myIrqHandlerVBlank):
Code:
if ( 0 == (REG_KEYINPUT & (KEY_L | KEY_R | KEY_UP))) {
if (tryLockMutex(&saveMutex)) {
if (swapTimer == 60){
int oldIME = enterCriticalSection();
swapTimer = 0;
sharedAddr[4] = 0x50000000;
IPC_SendSync(0x8);
leaveCriticalSection(oldIME);
}
}
unlockMutex(&saveMutex);
swapTimer++;
}else{
swapTimer = 0;
}Those are ARM9 cardengine.c new lines (inside void myIrqHandlerIPC):
Code:
if (sharedAddr[4] == (vu32)0x50000000) {
lcdSwap();
}It compiles and nds-bootstrap runs games... but it doesn't do anything when L+R+UP are pressed.
Edit: If I use 0x57534352 for sharedAddress[4], it activates successfully ARM9 myIrqHandlerIPC function, but it puts white screens and freezes the game. I think the problem is that execution doesn't return to game after IPC, but I need some help to continue
Last edited by xonn,
When I start NTR Launcher to launch a game, the system goes to a white screen after "LOADING", I think. I am using the latest hiyaCFW version, and 2.3 didn't work (also white screen) and both versions by unresolvedsymbol did not work either (colored squares on bottom screen)
2.2 works, but it does not have the options that I want to use (expanded/DSi RAM and such)
I've tried with multiple games with no difference.
Any ideas as to what I might be doing wrong or what I should try?

My machine is New 3DS XL
I have R4 with YSmenu that doesn't have timebomb anymore.
Is it worth it to install Twilightmenu? No, I will not install DS games on my 3DS, my DS games will be all on flashcart.
I'm asking if there any extra benefit for me using Twilightmenu

Yes. You'll be able to use DSi features, such as overclocking, and higher quality sound.
For overclocking, you need TWLMenu++ installed on both the flashcard and the SD card.
If I got that right, if I buy a Japanese DSi LL I can just install CFW and circumvent the Region Lock right? Also if I set Twilight Menu to auto-boot I don't have to worry about the Japanese menu either?
And I can confirm that using a Japanese DSi LL works great with TWL++ and related tools. My primary DSi is from Japan (the LLs were cheaper than the corresponding USA model XL). I'm running UNLAUNCH 2.0 and TWL++ 18.5.0 and everything is in English and no problems.Alright thanks!
Silly question I suppose...
What does "Derp-fix" mean as a check-in comment on a lot of the open source stuff I'm browsing? I assume it's like when you check in something that won't build or has some obvious problem and you need to do a quick check-in to make it work again?
I used to be hip, but now I'm more hip-replacement

Yes, it's for fixing a mistake in some code.Silly question I suppose...

thanks, I'll try that with a new same size card as soon as I can
1. I don't think anyone's tried that, but I really doubt it would do anything useful. They're really just not the same system and different capabilities.
