Dolphin (obviously) + LLE sound plugin (google it). So here I am, sharing the discovery (well, I am pretty sure many of you knew already). Without that much hope, I tried it with Mario Tennis 64.
I recently found that Dolphin (yes, the GC/WII emulator!) was also able to play N64 games. So far the best results were found with jabo plugin(s), let's say the game was playable. I tested several emulators and several video plugins in a attempt to find a way to play Mario Tennis perfectly. Please forgive me also if you already knew the news, but I think it may even become a sticky post. Please forgive my english, it's not my native language.
