What's new?

The DSi System Menu font is implemented, so the japanese text characters are shown for games with japanese text! (thanks to @RonnChyran)
Nightly homebrew nds-bootstrap build is now supported.

Bug fix

Power button now works again, for Unlaunch users without CFW on boot. (thanks to nocash for the fix code)

What's new?

Touch support has been added to the DSiMenu++ GUI!

Bug fixes

DSi/3DS theme: In order to avoid font corruption, the font is now reloaded whenever scrolling through games in the menu.
DSiMenu++ will now tell the launched homebrew to use NTR touch mode, if the homebrew (with DSi header) is recently compiled, and if not using DSiWarehax.
One example is GameYob (built into DSiMenu++), which has been recompiled with touch mode checking (included in latest libnds), so touch now works both in and out of DSiWarehax.
.launcharg files are no longer shown on 3DS/2DS.

Known bug

In nesDS TWL Edition (also built into DSiMenu++), touch still only works for DSiWarehax users, as recompiling it with latest libnds does indeed fix NTR touch, but emulator decides to crash after a few seconds.

This update of DSiMenu++/SRLoader/DSisionX brings lots of new features!

Acecard/Wood theme, which is a straight port of the original! (huge thanks to @RonnChyran!)
Place your theme in sd:/_nds/dsimenuplusplus/akmenu/theme, and go into DSiMenu++ Settings to use it.
Red, blue, green, yellow, pink, and purple colors have been added to the DSi Menu theme!
Flashcard can now be accessed if you're running DSiMenu++ from the SD card, and can be used a secondary device!
You can press Up/Down (DSi/3DS theme) or the R button (R4 theme) to switch between the SD and flashcard at any time.
The only downsides are that they shouldn't spoof a commercial game (with it's icon being used), and it has to make the console autoboot into it, or else the flashcard cannot be accessed/supported.
These flashcards are supported:
-DS-Xtreme (Untested. Unknown if it will work.)
-DSTT (Untested. Should work.)
-Original R4 (Untested. Should work.)
-R4 Ultra (Works.)
DSiWare can also be launched from a flashcard, if DSiMenu++ is started from the SD card. (Requires Unlaunch on DSi.)
It works by copying it to the SD card, so Unlaunch can run it.
After saving in the DSiWare game/app, please start DSiMenu++ again to transfer the save data back to the flashcard.
Further improvements to overall app stability and other minor adjustments have been made to enhance the user experience.
NOTE: This is a beta release, so there may still be some bugs left in.

Updating from v6.1.0

Overwrite the _nds folder and boot.nds file on the SD root, with the new ones from the .7z file.
What's new?

The AKAIO theme is now bundled as an Acekard subtheme. Select Adv.EvoI in settings.
The flashcard switch feature now only works with the R4 Ultra (www.r4ultra.com), as the other flashcards mentioned in v6.1.0 would either simply not work, or cause a white screen crash.
Bug fixes

Fixed some known bugs, such as crashing when launching a game using the DSi, 3DS, or R4 theme, and the Guru Meditation Error screen appearing when trying to open per-game settings in those themes.
