nds-bootstrap:

Thanks to the work of ahezard, Gericom, Apache, Robz8, _catcatcat, and shutterbug2000 and other contributors, we can now load NDS games from the SD card, without any flashcard/SLOT-1 card.

Don't expect high compatibility, but do expect many, many updates.

yeah it does, but it just goes to a black screen

Try updating the bootstraps in the settings screen.

 

[Gyrobax]

I just did that and it's still showing the black screen,

Are both screens black?

 

[Gyrobax]

yep, after the DSi boot up thing, it just cuts to black

What are your NTR/TWL settings?

 

[Gyrobax]

my settings are
ARM9 CPU speed set to 133MHZ
VRAM boost on ds/dsi screen on
Reset slot1 off
Console output off
Lock ARM9 SCFG_EXT on and bootstrap is set to release, and it's on v0.4.0 the latest release

Turn Lock ARM9 SCFG_EXT off.

 

[Gyrobax]

Yep, that did the trick, games are working again. thank you

Hi @ahezard ! I would not bother you, but is been a little since your last post... Do you have found anything interesting for bootstrap?

He should continue working on bootstrap this Friday.

probably working on all those thumb read things is my guess.

Hopefully

Dragon Quest games doensn't work because it uses THUMB mode too?

Pretty sure advanced RPG games use THUMB mode.

 

[vander263]

Yeah, i hope that these opcodes are implemented soon too

 

[Valery0p]

Ok I swear that he is also working on the Layton bug...
An information: why some games use ARM op codes and other THUMB op codes? There is a performance difference?

ARM instructions are always 32 bits long, while THUMB instructions are always 16 bits long.
On the GBA, ARM instructions were usually used for very fast and very small loops on the on-chip WRAM, which the CPU could access with a full 32 bit buss.
Data elsewhere in memory (including directly in the cartridge ROM) could only be accessed with a 16 bit bus so it was often more efficient to use THUMB mode.
It's likely that something similar is going on with the DS.

People who got Ace Attorney Investigations to work: what's your config? Mine is stuck on white screen and I have both bootstrap and TWLoader up to date...

 

[Damin72]

Any news form ahezard? Or he prepare something cool?
