Seemingly contradictorily however, the oft-considered best DS emulator is DraStic: it’s much faster, more accurate and less buggy, but has the limitations of being closed source and solely for Android 1, making it hard to peer into its development process. While development has slowed, DeSmuME is still the standout DS emulator for PCs. With currently only two major contenders for mature DS emulators what counts as a Holy Grail bug in DS emulation is a bit more difficult to define. There are far more than just two emulated systems out there and along with them a large share more incomprehensible issues. Of course, the previous article only covers two emulated platforms.

However, none of the issues have been conclusively resolved. Lior did much more research on solving Pinball Fantasies and byuu dug up a forum post implying that there is in fact a three scanline delay when enabling background layers on the GBA. It’s been two months since first writing on Holy Grail bugs in emulation and while it did pique the interest of many emulator developers there has been little movement on solving the bugs.
