All firmwares >= 5.0.0 are officially supported, older firmwares should be compatible but haven't been tested.
The app is pretty straightforward to use: themes are in SZS format and are extracted from the home menu RomFS, open a compatible szs, open a 1280x720 image to use as a background and click on save.
There is a complete tutorial in the release thread.

Features:
  • Lockscreen, home menu and user settings support for firmwares 5.0 up to 6.1.0
  • From 6.0 support for news applet and console settings as separate szs files, on <=5.x it's all in common.szs
  • Older firmwares have been confirmed to work but are not officially supported
  • Auto image injection, no external tools needed.
  • Support for custom layouts, with built-in examples
  • Auto image to DDS conversion
  • Auto NCA Extraction to easily extract the SZS files from the home menu (based on hactool)
  • Advanced tools to help people develop custom layouts or patches
  • Web version with Auto-Theme to share themes
The source code is available on GitHub
No installation is needed, just extract the files and run the main exe, this app requires .NET Framework 4.6, and works on linux through wine (Some features like image to DDS and NCA extraction are windows only).

In addition to the windows version there is also a web version, it has more limited functionality (eg. you'll have to convert your images to DDS manually), but you can use it to legally share themes with the Auto-Theme feature, you can find it here.


To share custom themes on GbaTemp you have to use Auto-Theme, read how in this thread, this is because
SZS files, either unmodified or modified with this app contain copyrighted data so they can't be shared here.

Change log
- Auto image to DDS conversion
- NCA Extractor: dumping theme files from your own console now it's much easier

    How do you know if the night will be good when you're asleep
  • BakerMan @ BakerMan:
    because i didn't say i was asleep
  • BakerMan @ BakerMan:
    i said i was sleeping...
  • BakerMan @ BakerMan:
    sleeping with uremum
  • K3Nv2 @ K3Nv2:
    Even my mum slept on that uremum
  • TwoSpikedHands @ TwoSpikedHands:
    yall im torn... ive been hacking away at tales of phantasia GBA (the USA version) and have so many documents of reverse engineering i've done
  • TwoSpikedHands @ TwoSpikedHands:
    I just found out that the EU version is better in literally every way, better sound quality, better lighting, and there's even a patch someone made to make the text look nicer
  • TwoSpikedHands @ TwoSpikedHands:
    Do I restart now using what i've learned on the EU version since it's a better overall experience? or do I continue with the US version since that is what ive been using, and if someone decides to play my hack, it would most likely be that version?
  • Sicklyboy @ Sicklyboy:
    @TwoSpikedHands, I'll preface this with the fact that I know nothing about the game, but, I think it depends on what your goals are. Are you trying to make a definitive version of the game? You may want to refocus your efforts on the EU version then. Or, are you trying to make a better US version? In which case, the only way to make a better US version is to keep on plugging away at that one ;)
  • Sicklyboy @ Sicklyboy:
    I'm not familiar with the technicalities of the differences between the two versions, but I'm wondering if at least some of those differences are things that you could port over to the US version in your patch without having to include copyrighted assets from the EU version
  • TwoSpikedHands @ TwoSpikedHands:
    @Sicklyboy I am wanting to fully change the game and bend it to my will lol. I would like to eventually have the ability to add more characters, enemies, even have a completely different story if i wanted. I already have the ability to change the tilemaps in the US version, so I can basically make my own map and warp to it in game - so I'm pretty far into it!
  • TwoSpikedHands @ TwoSpikedHands:
    I really would like to make a hack that I would enjoy playing, and maybe other people would too. swapping to the EU version would also mean my US friends could not legally play it
  • TwoSpikedHands @ TwoSpikedHands:
    I am definitely considering porting over some of the EU features without using the actual ROM itself, tbh that would probably be the best way to go about it... but i'm sad that the voice acting is so.... not good on the US version. May not be a way around that though
  • TwoSpikedHands @ TwoSpikedHands:
    I appreciate the insight!
  • The Real Jdbye @ The Real Jdbye:
    @TwoSpikedHands just switch, all the knowledge you learned still applies and most of the code and assets should be the same anyway
  • The Real Jdbye @ The Real Jdbye:
    and realistically they wouldn't

    be able to play it legally anyway since they need a ROM and they probably don't have the means to dump it themselves
  • The Real Jdbye @ The Real Jdbye:
    why the shit does the shitbox randomly insert newlines in my messages
  • Veho @ Veho:
    It does that when I edit a post.
  • Veho @ Veho:
    It inserts a newline in a random spot.
  • The Real Jdbye @ The Real Jdbye:
    never had that i don't think
  • Karma177 @ Karma177:
    do y'all think having an sd card that has a write speed of 700kb/s is a bad idea?
    trying to restore emunand rn but it's taking ages... (also when I finished the first time hekate decided to delete all my fucking files :wacko:)
  • The Real Jdbye @ The Real Jdbye:
    @Karma177 that sd card is 100% faulty so yes, its a bad idea
  • The Real Jdbye @ The Real Jdbye:
    even the slowest non-sdhc sd cards are a few MB/s
  • Karma177 @ Karma177:
    @The Real Jdbye it hasn't given me any error trying to write things on it so I don't really think it's faulty (pasted 40/50gb+ folders and no write errors)
