Disassemble the theme with YATA. Edit top image then reinject it.

I would actually gave trouble editing, not disassembling it. I don't have Photoshop, and I think MS Paint isn't quite up to the job.

I use gimp 2 for windows. It's somewhat like photoshop but a bit more intuitive. Also its free.

Thanks I'll try it. And if I want a scrolling BG for top and bottom screens, what resolution should I use?

The bottom image is already scrolling. But it's the same image over and over. I'm not sure the resolution for top and bottom. Someone here might though.

No, I want the resolutions for a theme of mine. And what about the lots of colors in YATA? Is there any guide for them?

The best way to do it would be to find a dual scrolling theme in this thread. I think there was a Yoshi one a while back. Disassemble one of those. As far as colors, what I did was for every catagory I put red, green, blue, any other random colors needed. Then I installed that. That way you can look at your 3ds and see where each color goes while editing. So you can be like "ok, first color for arrow button, I have red. On the 3ds I see that's the shadow color. I'll change that too.." and so on.
I don't think there is a guide anywhere yet that does this for you.

Thanks! I wanted to ask about sound effects... But I just heard that they can cause bricks.

Its a soft brick. Just be sure to test them on emunand, and make an emunand backup with emunandtool before installing. I linked the CWAV tool in a post on the last page. He tells you how to properly format your wavs in his release post.

But I'm on 9.9, sadly. [emoji17]

Oh. That sux man. You can still make awesome themes with the default sound effects. I haven't used custom cwavs in any of my themes.

Can I tell if a theme is safe / has custom cwavs? Or can I remove custom cwavs?

If a theme is posted here I'm sure it's been tested. If someone released a brick theme I'm sure they would be banned/punished immediately. You can extract cwav.bin from any theme with yata, and replace it with one from another theme.

Thanks! The problem is, I've downloaded themes from several sources. Is there a place where I could request people with EmuNANDs to be checked? Does the brick persist I remove the SD card?

As far as I know, removing the sd card reverts to the default them.if you have concerns I would just ask people if their theme has been tested. Or if someone could test it for you. I don't know of any other way to verify that a theme works.

So if removing SD reverts to default, why is everyone afraid of bricking?

I believe removing the SD card fixes a soft brick on sysNAND, since it reverts to default settings. However, don't quote me on that.

Honestly, there's really no consequence to soft bricking your 3DS with faulty themes. Backup your sysNAND/emuNAND theme exdata and restore it in the event of a soft brick. It's more annoying than devastating and can be fixed in a couple minutes.

The subfolder can be found in your 3DS folder in the root of your SD under exdata. EUR "000002ce", USA "000002cd", JPN "000002cc", respectively. Back it up and restore it if--when--you run into any problems.

I've softbricked my New 3DS several times now while experimenting with sound effects and as a result of seemingly general YATA bugs. In general, following guidelines and tips will help minimize softbricks.

So is it doable on 9.9 SysNAND, I only need to SD card, right?

You need a way to launch the gateway launcher in order to do a nand backup/restore, which isn't possible on 9.9. There is a difference however, between a soft brick and perma brick. Since themes are only on the sd extdata, it should be fixable by removing that sd. Some bricks occur from installing or editing software contained in the nand. Those require a port to be soldered to the 3ds board in order to reflash nand. Which i assume is also not an option for you, as I doubt you have a lower firmware nand backup.

But yeah, perma bricks are serious business and are sometimes unfixable.

Thanks! Can someone (with a NAND backup and mod, of course) test for me that themes can't cause unfixable bricks for a 9.9 user?

I'd just recommend to use extdata_tool to backup your extdata before you use a custom theme, then you can remove your sd card and go to Ninjhax 2.0, put your sd back in, and restore the extdata backup if you get a soft brick. Since themes are in the extdata, I don't think you can get an unfixable brick from themes.
