DWedit has released a new version of the NES emulator for the GBA (works on Nintendo DS too), heres whats new:

This build is extremely buggy, but Battletoads and Wizards and Warrior 3 no longer have graphical glitches in the main character animation.

There's a major bug in how it selects the tileset to display when a game starts up, so keep changing games until it boots the game properly.
