Try using a 16-bit or higher sound card (if you like your 8-bit, that's fine too :)
For added realistic sounding instruments, use wavetable synthesis software, such as WinGroove
If a certain anime series has more than 10 midis available, there will be a seperate page for it.
If you see just a midi file name but no song title, it's probably because I (yes, your old faithful yuichi) didn't know what the name of the song is. (If you know it, could you fill me in on it? Thanks! =)
