Mic has released a new version of the best Nintendo DS Emulator for windows, heres whats new:
GPU: Fixed some texture transparency problems
GPU: Fixed some bugs when rendering 16-color rotoscale OBJs
GPU: Fixed some bugs when rendering extended palette rotoscale BGs
MMU: Added experimental SPI touchscreen handling
MMU: Fixed some bugs in the handling of long filenames in the FAT
GUI: Improved timer event handling a bit
GUI: Fixed .zip loading
GUI: Added support for .7z loading
The SPI touchscreen handling is not perfect yet and only works somewhat, so the old faked method is still used as a fallback for homebrew ROMs using libnds.
