DSi mode support for DSi-Enhanced/Exclusive games

[cole36912]

This is not an Issue. I was just wondering because I haven't seen much discussion on this. I know the features that use this are pretty rare in the nds library but I think it would make it more like using a real cartridge and it is something flashcarts can't provide(except for one). So is it possible? And are there plans for it?

[piratesephiroth]

yeah I thought the enhanced CPU clock was already DSi mode but nope, heh

[RinMaru]

That's what I thought lol

[piratesephiroth]

well nds-bootstrap already has access to the DSi clock speed and the SD card so the remaining features (camera and WPA wifi) are probably possible too.

[NightScript370]

Hasn't this already been implemented?

[RocketRobz]

DSi mode doesn't work with DSi-enhanced games yet.

Here is the debug output with IS-TWL, in dsi mode and nds-bootstrap v0.32.0 of 5325 - Mario vs. Donkey Kong - Mini-Land Mayhem! (USA)

It is crashing with the following error

[[ Fatal Error: ARM9CPU stopped running because "Data access exception" occurred. ]]

The MPU end up badly configured when the dsi enhanced game runs via in nds boostrap : only 4MB is configured instead of 16MB. This is the cause of the crashes above.

[ahezard]

configuration of the MPU in 5585 - Pokemon - Black Version

[ahezard]

As a reference here is the correct configuration of the MPU of 5585 - Pokemon - Black Version in no$gba in dsi mode

[ahezard]

Some SCFG registers are wrong

What are the main issues With getting this feature working on 3DS? This isn't just an issue for Playing DSi Enhanced Games, but also DSiware. Since the 3DS has a title limit and the same amount of storage in TWL nand as a real DSi it makes more sense to load from SD anyway.

Is this the cause of when I try to boot a DSi enhanced game via TWiLight Menu++ the upper screen turns black and the bottom white?

You would be correct. It is not fully implemented and thus not working in DSi mode.
You can change to DS-mode in either global settings or game-specific settings to mitigate this.

Some progress has been made!

Most games will no longer crash with a top black screen and bottom white screen, and on DSi, it'll not show the nds-bootstrap error message. Depending on the ROM, it'll start with either white screens or black screens.
However, card reads are currently broken.
On DSi consoles, the card read code is stuck in a loop, with the card read LED staying on forever.

Some <=16MB ROMs will boot in DSi mode on NO$GBA though, but keep in mind that reading/writing save data will cause the game to crash. If the ROM is DSiWare, it'll show an error screen instead.

you've got pokemon black/white working with the current progress,i i can load a save and even see my 3ds connect to the wifi (and get a "this service has been discontinued" message on xtransceiver.

not working is pokemon black 2/white 2, it gets the menu and then black screens on loading save.

[RocketRobz]

As of later commits, most DSi-Enhanced games, all 5 DSi-Exclusives, and some DSiWare, all boot in DSi mode!
After nearly 3 years since this issue was open, this has finally been implemented.

Do cheats work in DSi Mode?

Yes, they do.

I can confirm this as well. White 2 will now launch in DSi-mode, but when you try to launch a save from the main menu it goes to black screens and has to be force closed with L+Down+Select (quick pressing power doesn't quit).

Is this working on 3DS or is it DSi only?

Is there a Compatibility list for Working DSiware games?

It's still new, so you'll need to test some DSiWare yourself.
If you're testing on DSi, make sure DSiWare booter is set to nds-bootstrap.
