ROM Hack Need a good tutorial on removing region lock

[DarkFlare69]

I have a .3ds and .cia file. I want to remove region lock on both, or at lest one of them. I know I'm usually the one to write tutorials but I need this favor, please.

Edit four bytes at 0x2018 offset in icon.bin to 0x7FFFFFFF (little endian).

Really? Never heard of that. And why would region data be stored in the icon?

Ask Nintendo lol.

For reference, you can read about icon.bin format on 3dbrew: http://3dbrew.org/wiki/SMDH. And please note that region value is little endian, which means you have to write 0xFFFFFF7F to icon.bin file

Probably because it's the one thing that all 3DS systems regardless of software version can load properly since it also allows the game cart to prompt for updates if the minimum firmware of the game isn't met. Since that's the case, it probably stores the region there so the system can check it to see if the system that it's running on matches what's in the icon.

Ok, I'll look at this tomorrow, thanks. I might need you to verify if I did it right when i do it @RainThunder

Then it's already region free. You don't have to edit anything.

But it's not. It only works on USA, I had someone test PAL and it didn't work.

What game are you working with?

 

[DarkFlare69]

What game are you working with?

MK7

 

[Zhongtiao1]

PAL uses 50hz encoding and NTSC uses 60hz. Don't know if that has anything to do with it [emoji14]

 

[Jarrad]

Is this only possible with Gateway?

You can't do this on Sky3ds, can you?

 

[Justin20020]

on sky3 you can use regionfour. its my option to play other region games

do you know if achhd is compatible w/ regionfour?

 

[Justin20020]

What is achhd?

 

[duwen]

Happy Home Designer uses the new AP and, at present, isn't compatible with Sky3ds - otherwise it would work with RegionFour/Ninjhax-Homebrew-Regionfree-launcher the same as any out of region game does (ACHHD and FEiF aside).

 

[Justin20020]

Oh I dont know. The dumped version of achhd is bad and it wont work on gateway. Achhd isnt in the template file of the sky3ds. So it wont work too. Otherwise, when its in the template file, just load an homebrew launcher and check the game with regionfour. So it will work then
