ROM Hack [Release] AGB_FIRM Signature Patcher + GBA ROM Converter

[Riku]

This release consist of IPS patch for AGB_FIRM and ROM converting program, both done by me.
Credit for patched New3DS AGB_FIRM goes to motezazer

My method require you to install patched AGB_FIRM CIA into NAND memory replacing exciting one. Now... AGB_FIRM is an optional System Title that was introduced with 3.0.0 firmware update and was never included with Card updates. Which means you can't really break system by deleting it or installing corrupted AGB_FIRM, in fact you may even don't have it installed (if you using old system and only updated from game and never used update via internet). But! You may break system if you delete wrong system title in process, so I don't take any responsibility for any possible damages. If you are not comfortable with it - stop reading right here.

Basic steps for Old3DS / 3DS XL / 2DS:
1) Download '0004013800000202' title 'v3665' using 3DNUS

2) Launch 'Old3DS_AGB_FIRM_v3665_SignPatcher.exe' and apply patch to '0004013800000202.cia'

3) Try to install patched CIA from FBI:

Spoiler

Don't forget change destination to 'NAND' (L button), if you don't have any errors - congratulations, you're finished. If you got error, that means you need to remove previous version of AGB_FIRM before you can install patched one. Switch mode to 'Delete Title' and and destination to 'NAND' and scroll down until you find title with Title ID 0x0004013800000202:

Spoiler

Triple check you selected correct title and press delete, after this you should be able to install patched CIA without any errors.



After installing patched AGB_FIRM you can start using my '3DS Simple GBA Converter' program and play your favorite GBA games. Enjoy.

For New3DS process basically the same except Title ID is 0004013820000202 v4816.

This is going to make a lot of people happy. Great work!

Edit: This is probably better suited to ROM Hacking, Translations and Utilities, perhaps a mod can move it there.

 

[Crass]

Nice work!

Your footer generator link broke.

Can you re-upload it?

EDIT: Nevermind. Avast thinks it contains a virus. You might want to examine it and see why it does that.

 

[cearp]

thank you very cool!

what is the footer generator?
i guess the gba converter gives us a useable file for the 3ds, but the footer is for what?

 

[hippy dave]

Good work! I sent you a pm re: n3ds support.

 

[gojeta09]

emunand works with Gateway?

@Riku

I have N3DSXL EUR 9.0 / Sky3DS / Gateway if you want i try something for you

 

[froggestspirit]

Alright, I'd like to ask about the technical details if I may. I tried looking into this with @bobmcjr , but neither of us got it working in the past.
Anyways, I'm excited to try this out, great job! And I can help with N3DS support if you want, PM me.

 

[Edolas]

Will n3ds be supported soon ™?

 

[Riku]

thank you very cool!

It's not fully reversed (especially EEPROM part), so I decided not mix it with converter so people can have some freedom until we have some sort of compatibility list.

 

[Apache Thunder]

Looks like Avast is false flagging it just because you chose to pack exe with UPX.

EDIT: Even after unpacking with UPX, it still false flags it.

Ok back to being serious. From what i'm reading this will work on old and new3ds but there's a very minute chance of a brick if we delete the wrong system title correct? Or will this not work on a new3ds that uses pasta?

 

[nacimem]

the cia 0004013800000202 is the same for EU, US or JP ?

 

[hippy dave]

Won't work on n3ds right now, needs to be adapted.

I hope the source of the tools could be released at some point, or at least some mac versions

 

[powersaver]

Can the patched AGB_FIRM be installed with PBT-CFW? Would this cause a brick?

 

[zoogie]

the cia 0004013800000202 is the same for EU, US or JP ?

According to 3dbrew, it's the same for those 3 major regions (and maybe korea too)

Does anyone have the correctly patched cia's checksums?

 

[VashTS]

emunand works with Gateway?

I wonder the same...

 

[Sizednochi]

I wonder the same...

Pasta CFW only.

Correct me if I'm wrong, but aren't you the one who posted a screenshot of a GBA title running on a 3DS but refused to release your method and telling people to do their own work?
