Instructions:

1. Download the .7z file.
2. Extract both .nds files, to sd:/_nds.
3. Extract the .ver file to sd:/_nds/TWiLightMenu.

What's new?

• Homebrew compatibility is back! Compatibility should be more or less the same as on v0.0.3.
  NOTE: This currently does not work with SnemulDS, due to it having a different interrupt dispatcher from libnds-compiled homebrew.

Bug fixes

• Fixed returning to TWiLight Menu++ with L+R+DOWN+B for 2 secs, if v7.1.0 or later is installed.
  This feature will no longer work with TWiLight Menu++ v7.0.0 or prior, unless if the TWiLight Menu++ CIA from v7.1.0 is installed.
• Fixed save issues in some games that didn't have them before.
  Some games may still have the issue, even with the fix implemented (ex. DBZ Supersonic Warriors 2).

Regression

• GBARunner2 now doesn't work. Use TWiLight Menu++'s GBARunner2 feature, as an older version of nds-bootstrap is used there.
