Hacking sakura is here

[Urza]

Probably because the G6DS Real came out before the M3DS Real, and modifying the hardware to load a file under a different name wasn't worth the trouble.

 

[BinarySoup]

yea I dont anything of what you said
can you rephrase it?

are you sure he anything of what you said?

 

[11gardir]

I think the current firmware has a g6dsload file anyway, so why change it?

 

[Chrono_Tata]

So am I correct in thinking the Sakura is somewhat like a prettified version of the Games and Music and the moment?

Pretty curious how this whole thing is going. Maybe they didn't finish the firmware on time cause what we have right now is not so much different in function from the beta.

 

[Phaethon]

I've heard that Sakura can't run games (roms)..is it true?

This seems to be the right one with commercial support:

http://down.gbalpha.com/GBalpha/Softwares/..._Ver111_JPN.zip

You see the difference? On the "official" site m3sakure.cn there is this one:

http://www.m3sakura.jp/M3Sakura_Ver111_JPI.zip

The one on sakura.cn calls "JPI" and the one from gbalpha calls "JPN".

After information from M3 themselfes, they have released two versions. One "official" without the rom support (on the sakura site) and one with support on the gbalpha site. I cant test it because i dont habve a japanese M3, but it seems that the gbalpha version download is round about 2MB bigger then the "official". Try it and post your results.

 

[ridgecity]

has anybody tried running in G6?

 

[gangsterboi]

Few, and i thought sakura was going to be media/homebrew cart.

but why launch a firmware without rom support? To see are reactions?

has anybody tried running in G6?

Yes, i have with no success. It says something about m3 Japanese only.

But i havn't tested this version with rom support. And if that doesn't work i will keep trying it without various different files.
I'm just downloading the version with rom support. But it might take while because it's downloading at 12Kbs per sec.

Update: This version of the firmware has a extra 29 files directly in the system folder most of them related to cheats so it must boot roms. Lets see if it has any success on g6. I'm putting them onto my G6 and shall have results in roughtly 7-10 mins. If it fails i shall see if deleting files can change that.

If i see a document which has the following code in it; "NO LET G6 BOOT". I may try to change that.

 

[thedicemaster]

doubt it works on G6
official statement said it would only function on japanese M3real and m3sakura cards.

older messages however do state that with a future update G6 and non-japanese m3real cards will work too.

 

[Phaethon]

Quote from Danny:

We want the M3 sakura Eurpoean version can be released asap .
But we need to fix some firmware problem .
It is hard to tell you the actually time .

 

[gangsterboi]

UPDATE:: I doesn't work. I'll show you what is says on the screens. I will try to get images but for now i will just type it.

Few! and thats all of it, writing it out took longer than expected.

I'll try deleting some files. but i doubt it will work.

 

[thedicemaster]

i can tell you perfectly fine what caused that error.
m3sakura tries to load using coding for an m3real's microSD.
it however finds G6 internal memory, which it can't work with causing a FAT error.

 

[gangsterboi]

Is there any way to remedy this?

 

[thedicemaster]

it's possible, but it's quite some work.
step1:figure out what file tries to access the internal storage space.
step2:dldi patch it for G6
step3:check if there's a block against alternative dldi patches/autopatch and remove it.
step4:remove the cart check in m3sakura itself.

this all is more work than getting m3sakura japanese to work on an unmodded english m3real.

 

[gangsterboi]

mmm.... well i certainly don't think i will be able to do it, i don't even have a chance of figuring out what file tries to access the internal storage (if anyone's knows how please tell me i'm quite interested in it) At first i thought it could be the "Check disc for NDS version0.4" but now i don't think it is. So I guess we will have to wait untill the official version for European versions for m3 or g6.

Offtopic;

I copyied the moring timer file across to my g6 and used the old firmware (3.0) and it appears to just be the homebrew app. But why have it on the sakura system? I thought they would at least embed it into the actual firmware instead of having the homebrew app hidden in the system files. I guess they need the Homebrew App as a .nds file to be able to implement it as a part of the firmware.

 

[cory1492]

If anyone is interested, this is the log from 1.11 from the sakura site from a fresh install directly trying to run a retail game (in the spoiler tags, note the version didn't seem to be updated and there is still an error right at the bottom - not homebrew.) I don't see any cheat files whatsoever in the package though, I'll keep reading previous replies.

I was able to decrypt and dldi patch g6dsload.jp yesterday without issue, though I never tried it on anything afterwards. IQ_132 (I think that was the name) made a tool to quickly decrypt the headers to get a plain ds.gba out of these files.

 

[ridgecity]

my god you guys are geniuses... I don't understand any of what you all said... lol you think it's possible to make it run for G6?

 

[gangsterboi]

can u provide a download link for those decrypted and dldi patched files?


And the version of firmware which has cheat.db is downloaded from here;

http://down.gbalpha.com/GBalpha/Softwares/..._Ver111_JPN.zip

 

[thedicemaster]

it's most certainly possible to get it to work on a G6.

if you have enough knowledge about hacking such stuff you could theoretically even get it to work on an R4.
although that would require a lot more work.

i do think by the time someone get's it to work on a G6, it will already work on eu/us m3reals.
because getting it to work on a G6 requires the same things as getting it to work on a eu/us m3r +some more.

 

[gangsterboi]

So maybe we should wait for it to be released on the eu/us m3r then hack it. Or just wait till it gets released.

 

[cory1492]

gangsterboi: yep, that's the one. Thanks (it took me a while to dig up the other post with that link too.)

Definitely runs retail roms with those files, here is the log:

my god you guys are geniuses... I don't understand any of what you all said... lol you think it's possible to make it run for G6?
Either we are geniuses or only trying really hard to look like the real deal

Yes, I think it's possible to make it run on G6, but probably not for anything other than what moonshell does (even with the extra files G6 does not work identically to M3, but the same check as region, then dldi, could well be the only ones needed to make it run.)

There was a fellow yesterday working on taking off the region check (I'm still wondering how to extract the separate arm7/9 bins from that thing), after that it is just skinning that really needs to be done to make it work on other regions. Unfortunately, I'm leaving for the weekend in an hour or so and can't afford to waste much more time on this stuff today (lest I wind up nekkid in a strange city because I didn't get a chance to pack

)

As for the patched files, any dldi tool can patch it as-is, and changing the crypt is not hard - but that check would need to be killed (not just the jal after it) before it would work on anything (it is checking the M3 hardware directly.)

edit:/ after a couple runs I got crashing, so I can't say it's stable - PC chkdsk returned this issue:
QUOTEThe size of the \SYSTEM\m3sakura\bgbmp.dat entry is not valid.

also, if the game is launched with the X button instead of a/b, it brings up some kind of cheat menu (can't read anything in it myself.)
