Sources for World of Game Mods (MOD linx)
These are web-sources where I downloaded some of the game mods from. Of course, there aren't all sources mentioned, many tunes are ripped from games by myself or are sent to me by some visitors of my site. Also sources of some tunes are unknown to me.
ExoticA - Site dedicated to Amiga's music, especially exotic tunes, but recently enlarged also with "Unexotica", which is site with plenty of game tunes for Amiga, including normal mods. This site really rocks and it's my definite recommendation if you're looking for Amiga game and non-game music.
Rpgamer - This site is realy good source of anything for roleplaying games (RPGs) and above all they've very big collection of tracked videogame arrangements and remixes.
SSTrax - This page should be dedicated to all tracked remixes of console/computer tunes, but unfortunately till now it isn't up. Good thing is, that I have most of their archive downloaded and available from here :)
Back to the Roots - Really must-visit for all Amiga's freaks - games, music, database of titles and much much more!
AMI Sector One Network - Another nice Amiga's site that has the similar type of contents as Back to the roots, so it's various Amiga's stuff including game music
Amiga Soundtracks - Amiga page with many game tunes, nice thing is that only mod tunes are there (not exotic formats).
X-Treme Game Music - Only the best game music in various formats (Midis, Mods, SPCs etc..)
Fading Twilight - Greatest music source for all the Atari (ST/Falcon/other) platforms. Not only game-music, but also demo music and lot of other stuff for these computers downloadable here!

Sources for World of Game Mids (MID linx)
These are web-sources where I downloaded some of the game mids from. Of course, there aren't all sources mentioned, many tunes are ripped from games by myself or are sent to me by some visitors of my site. Also sources of some tunes are unknown to me.
Videogame Music Archive - Source of many many videogame midis, unfortunately they removed the PC section, so you'll find there only arranged Midis from systems other than PC. But the archive is really big, more than 8000 pieces!
Laura's MIDI heaven - Another site with plenty of Midis (not only game!), and what's important, they have also cute and nice PC section! :)
Quest Studios - Great site for all the Sierra fans - you can find lot of Midi music from great Sierra's adventures, most of them greatly re-arranged for todays Midi sound-cards!

Other videogame music pages
Where to find some MP3s from music of computer games? Look at some of these links
AmigaMusic.com - Do you like Amiga music but would you be more content to have all the game tunes in MP3s? Then, this site is for you - instead of plenty (though cool, small, cute and nostalgic :) ) MODs you can find lot of great Amiga game tunes in MP3!
RPGamers.net - This site has very big archive of videogame MP3s and is relatively long time online, so there is chance it won't go down soon. But the connection is very slow, so if you'll want some MP3-s, you could look at some FTP mirrors, also good idea is check theirs forums and look for some FTPs
Gamingforce audio - Very good forums, go there, and check "My music" section. You'll sure find some working FTPs with plenty of game music! :)

These utilities are my recommendations for using fith computer and game music. At leas I was very satisfied with them
DeliPlayer - Awesome music player which recognizes more than 150 music formats (mostly Amiga's exotic formats, but also MP3s), has archive support and cool UI. It's must have especially for Amiga's mods listeners.
