???
Bootstrap build has been added as a per-game setting!
Improvements

@profi200's improved SD code used in fastboot3DS, and @shutterbug2000 & @ahezard's NDMA code used in nds-bootstrap, are now used to slightly boost SD reads.
Optimized .bmp image loading, so box art will be loaded a bit faster as a result.
Bug fix

Updating from v6.8.0 and later

What's new?

If TWiLight Menu++ is being ran from the SD card, when launching a game with nds-bootstrap on flashcards, nds-bootstrap's settings on the SD card will be synced to the settings on the flashcard.
nds-bootstrap version is now shown on flashcards.
Bug fixes

When accessing the flashcard directly from TWiLight Menu++ on the SD card, when trying to access the Settings screen, it will now boot if it doesn't exist on the flashcard.

Bug fix (Rev 01)

nds-bootstrap.ini is now saved to flashcard, if TWiLight Menu++ is being ran from there.

6.8.3.3
Bug fix

Fixed reading from (ROMpath)saves instead of (ROMpath)/saves, if ROM path has no slash at the end in settings.ini.

6.8.3.2
Bug fix

As the DSi, 3DS, and R4 themes hide a folder called saves, the Acekard theme now hides it as well. (thanks to @Epicpkmn11)

6.8.3.1
Bug fix

Main Menu: Fixed the path of the folder of saves being left out when saving to nds-bootstrap's .ini file.

6.8.3
What's new?

To speed up loading the ROM list, the DS ROM saves will have to be moved to a folder called saves, which will be in the same folder as the DS ROMs (ex. roms/nds).
TWiLight Menu++ now expects those saves to be in the saves folder.
This change does not affect DSiWare, GB©, or NES saves.
Force DSi mode option added.
Currently, the regular option works the same as the forced one, as nds-bootstrap has not yet been updated to reflect that change.
Bug fix

If the app is being used on an R4iDSN-related flashcard (R4 Ultra, R4i Gold RTS), it'll have nds-bootstrap force-patch sleep mode for it to work on DSi and 3DS consoles.

What's new?

Added option for SCFG access in Slot-1. Allows setting extended memory mode and/or TWL clock speed in flashcard homebrew.
With that setting turned on, when launching TWiLight Menu++ on your flashcard, TWL clock speed will be set on boot, and you'll be able to set CPU speed and VRAM boost settings in the settings screen and per-game settings.
DS menu Acekard theme by Vulpes-Vulpeos (fixed by me) has been added!
DSi theme: When touching the arrow button, it is now shown pressed.
If a saves folder does not exist in the folder of the .nds ROM(s), TWiLight Menu++ will now create it when launching your ROM.
Bug fixes

Acekard theme: Fixed list view causing Guru Meditation Error. (thanks to @Epicpkmn11)
Fixed soft-resetting in Slot-1 DS cart games bringing you to Unlaunch menu instead.

What's new?

Volume and battery indicators added to DSi, 3DS, and Acekard themes!
For the Acekard theme, only the DS menu and Switch themes for the AK theme show the volume and battery (icons for AK themes added by @Epicpkmn11).
Also, in DS mode, no volume icon will be shown, and instead of showing 4 battery bars, it'll show 2, and on DS Phat/Lite consoles, it'll be green instead of blue, to match the console's power LED light.
You can now have multiple saves for your games! Up to 10 .sav files can be used.
To access the option, open up per-game settings.
The TWiLight Menu++ CIA is now shown on the 3DS HOME Menu.
As a result, on next boot of the app, it will load faster, and the TWiLight Menu++ Launcher has been deprecated, as the next version of it will just be an updater.
If your on a Panda/Dev DSi unit or a 3DS/2DS, a game console select screen will be shown, if it's your first time using TWLMenu++.
A new animated icon for TWiLight Menu++ has been added! (made by @vulpes-vulpeos)
The alternative names (SRLoader and DSiMenu++) have been dropped to avoid confusion. (suggested by @NightYoshi370)
As the new nds-bootstrap release (v0.15.0) breaks compatibility with GBARunner2, the old hb bootstrap is still used to boot GBARunner2.
If you're running TWLMenu++ from a flashcard on DSi or 3DS/2DS, the HOME icon is now shown on the DSi/3DS theme, where you can touch it to return to system menu.
Bug fix

Fixed not saving hb rom's bootstrap file (thanks to @Epicpkmn11).

What's new?

After a while with only two 8-bit emulators (nesDS and GameYob) built-in, two 16-bit emulators (jEnesisDS and SNEmulDS) are finally added!
That's right! You can now run Sega MegaDrive/Genesis and Super Nintendo (SNES) games, thanks to the new RAM disk feature in nds-bootstrap (starting with v0.16.0)!
NOTE: If you're a flashcard user, you do not need to follow this below, as RAM disk will not be used on flashcards.
You'll need SegaMD.img for Sega MD/Gen games, and SNES.img for SNES games. Both should be in sd:/_nds/TWiLightMenu/emulators. Check the nds-bootstrap v0.16.0 release page for creating the .img files.
For SegaMD.img, the ROMs can be placed anywhere (especially the root) in the .img file, but for SNES.img, the ROMs should be placed in the snes folder in the .img file.
Like with save files, you can select up to 10 RAM disk .img files for homebrew.
The files will need to be placed in the ramdisks folder, which is in the same folder as the saves folder and the .nds ROMs.
Cheat support is finally added! (special thanks to @Epicpkmn11!)
Cheats will be read from usrcheat.dat at sd:/_nds/TWiLightMenu/cheats.
While all of the themes will read the enabled cheats, currently only the Acekard theme has a theme menu where you can enable/disable cheats.
DS menu Acekard theme updated! (by @vulpes-vulpeos)
Bug fixes

Fixed touch for buttons on AP message not working in Acekard theme. (by @Epicpkmn11)
Restored two missing frames to the animated app icon for system menu. (by @vulpes-vulpeos)
Animated icon now only uses one palette line for all 8 frames.
This is done so that the 3DS HOME Menu will show the icon properly.

7.3.0.1
Bug fix (by @Epicpkmn11)

DSi theme: Fixed photo randomizer not working.

7.3.0
Includes nds-bootstrap v0.17.0.

For this release, instead of doing the usual What's new?, Improvements, and Bug fixes listing, the names of the contributors will be listed for each change/feature.

@RocketRobz

Sega MD/Gen and SNES ROMs can now be launched by themselves from the SD card, instead of using a RAM disk!
How it works is that nds-bootstrap creates a .img with the launched ROM inside the RAM, and then the emulator reads it.
For your Sega MD/Gen ROM to show, it must end with .gen.
Sega Master System and Game Gear ROMs can now be launched!
S8DS (by FluBBa) will be used to run them, but there's a bug when it comes to launching a ROM passed as an argument.
You will need to press L+R, and then B, after the ROM boots, to have the sound working.
You can now make the loading screen in nds-bootstrap dark, and/or have it shown on the top screen!
Acekard theme: Fixed ramdisks/saves folder being created on SD root.
Improved homebrew detection. If the ROM has 00 as the maker code, then it'll be launched as homebrew.
Removed .launcharg support, due to it causing crashes, such as being stuck on Now Loading... in the DSi or 3DS themes.
Main Menu: Text is now shown if ROM wasn't previously ran.
@Epicpkmn11

DSi/3DS theme: You can now rearrange your games! Press Up to pick up your game, press Left or Right to move it, and then press Down to place it in the new position.
You can also switch pages during the rearranging process.
(requested by @ChampionLeake)
DSi theme: To access some games that would take a while by just holding Left/Right, drag the scroll window on the bottom using your stylus.
You can also swipe the icons, which can also be done on the 3DS theme!
Cheat menu can now be accessed on all themes!
You will need to move usrcheats.dat from sd:/_nds/TWiLightMenu/cheats to sd:/_nds/TWiLightMenu/extras.
DSi theme: A photo is now randomly shown like on the original DSi Menu!
Place your .bmp files of any name, in sd:/_nds/TWiLightMenu/dsimenu/photos.
NOTE: Rev 01 of this release fixes a bug which makes randomizing not work, so please download Rev 01 instead of this release.
R4 themes can now be loaded from the SD card!
Place them in sd:/_nds/TWiLightMenu/r4menu/themes. The .bmp files must be converted from 24-bit to 16-bit (X1 R5 G5 B5).
theme.ini is currently not read.

What's new?

If TWiLight Menu++ showed the SD removed message before the ROM menu appeared in the previous versions, you can now disable SD removal detection.
fatTable.bin is no longer created/modified at sd:/_nds/nds-bootstrap each boot or return to the app.
Saves write cycles on the SD card.

What's new?

(@Epicpkmn11) Enabled cheats are now saved to sd:/_nds/nds-bootstrap/cheatData.bin!
This allows more cheats to be saved.
Cheats that patch out AP will work as well. (Tested with Pokemon B/W 2 by VoltZ)
R4 theme: Menu now cuts in, instead of fading in, like on the original R4 firmware.
DSi, 3DS, and R4 themes: Cheat list can now be scrolled by holding Up or Down on D-Pad.
Found bug

If no cheat is enabled, then nds-bootstrap will crash on white screens, before the game boots.
The only way to avoid this bug, is to revert to v8.2.0.

Bug fix

Fixed major bug where a game wouldn't boot in nds-bootstrap because of no cheats enabled.

NOTE: This should hopefully be the last release for a while. :P

Check here on how to update TWiLight Menu++.

Includes nds-bootstrap v0.19.5.

What's new?

Cheat file, while still limited to 32KB, is no longer truncated to that size.
Should reduce slowdown introduced by loading the file in nds-bootstrap.
You no longer need to hold L for the following games to work:
-Star Wars Episode III: Revenge of the Sith
-Tony Hawk's American Sk8land (EUR)
Bug fix

Acekard theme: Fixed usrcheat.dat being deleted instead of cheatData.bin, if no cheats are enabled.
