Hacking r4decrypt

[fryguy]

Just tried the R4 file on my M3 Simply. Works fine

 

[Maikel Steneker]

I tried the R4 Firmware on my M3 Simply too, and it worked

Maybe someone can make a patcher, so I can use the R4 Firmware from now on (if I like

).

Something that doesn't work: I tried to put the patched R4 firmware on my SD-card together with DSOrganize. I booted the original M3 Simply firmware, started DSOrganize, renamed _DS_MENU.DAT (the M3 Simply firmware) to _DS_MENU.M3.DAT, and renamed _DS_MENU.R4.DAT (the renamed, patched R4 firmware) to _DS_MENU.DAT. When I restarted the DS, it reported that it couldn't find _DS_MENU.DAT. I had to delete it on my PC and copy it again

But it's great this works! Though I don't know the purpose of it

Now let's wait for some smart guy who makes a homebrew firmware for the M3 Simply and R4. I wanted to use DSOrganize, but I don't know how I should boot my original games... Maybe I am going to use LMP as firmware if I buy another SD-card for my music

I suppose this is for people who don't like waiting the extra time for the M3 team to release their version of the update or for people that expect either the m3 or the r4 team will discontinue the product one day and maybe the other will continue working on the software for it.

As for me... I'm just awful curious.

btw, does anyone know if there's an archive of M3 simply & R4DS software updates anywhere? I've got m3 1.02, 1.03, and 1.04 and R4DS 1.07 and 1.08.

Here maybe?

Excellent, thanks

Excellent, thanks

No problem

Well, that includes me

But future firmwares have to be edittable like this... I would certainly use it! For example, when R4 1.09 comes out to fix games like that tennis one, I'll put the patched version on my M3 Simply. When the original one from the M3 Team comes out I will use that one again

As for me... I'm just awful curious.

Yes, I am too, but that's not really something usable

Like Seyiji said: linfoxdomain. It has a collection of M3 Simply firmwares from the very first one to 1.04 (newest) and R4 firmwares from 1.04 until 1.08 (newest).

Come to speak of it, are there any R4 firmwares prior to 1.04? If so, why didn't they start at 1.00, so the version numbers with the M3 Simply firmware would match

?

 

[iamwhoiam]

yes there were pre-1.04 firmwares, because R4 was released first remember

I don't, 'cause I didn't know

I am just new to this whole thing. When I got really interested in flash card, the M3 Simply was just released.

Perhaps some clever guy or girl will
- find out to make POR running on every micro sd-card?
- find out to make also the latest 'problem' games running on the R4 (even before the R4 team does)?
That would be great! I don't like Castlevania, but it would be great to play Tony Hawk's Downhill Jam with playable speed.
QUOTE(lafleche @ May 17 2007, 01:51 PM)and also hope that some idiot won't release a version which bricks the DS....'cause that is my greatest fear... unless this forum 'installs' some kind of QA on private firmware for the time being I will stay far away from non official firmware

I also thought of this, but I don't think there is a really high risk. Sure, they can make it, but they can with regular nds-files too. Actually, there are 2 DS brickers...

Maybe someone should encrypt them and make some way to recognize them, so when someone else does it is pointless

The obvious update to the batch file. Can now convert between CHEAT.DAT and USRCHEAT.DAT

@echo off

This makes it a lot easier! Thanks

Btw, you shouldn't use bugmenot

what do I need to change to get English R4 firmware on Chinese R4 hardware?

 

[darksavior]

maybe now it might be possible to somehow switch the menu screens so you can select the games with stylus...

 

[iq_132]

what do I need to change to get English R4 firmware on Chinese R4 hardware?

As promised, here's my patcher program.
Right now, it can only patch the region for the newest Firmware (1.08 - r4 / 1.04 - m3) [it can patch between r4 english & m3 english for versions from 1.00 - 1.04 and 1.04 - 1.08], but I'll try to fix that later.

Wow this is great news, waiting to see what will happen next

 

[iamwhoiam]

I've updated the latest batch file by bugmenot52 on the first post

Wow, that rocks! Thanks a lot! I'll try it later today!

Does this mean R4 Clones?

 

[Ad_Enuff]

Does this mean R4 Clones?

Yup! It means every competitor now can use their code and bash out cheap clones.

On the plus side, it could mean R4 going open source and with that it could mean fixes come faster and the old download play problem could be fixed for good.

It was bound to happen eventually anyway, its obvious that the M3 and R4 are the same with a few minor cosmetic tweaks so both must of known the encryption or gave each other the source.

At this point I'm unsure if breaking the encryption is a good thing or not....time will tell.
