After my last post I done a quick search for mod codecs for windows & came up blank other JVC video mod files.
I would be interested in how your media player in Win7 is playing mods Marmor, I have tried in both Win7 & Vista both of which say "no thanks" as it thinks they are video files. I currently use OpenMPT to play tracker music as well as convert them to wave files, export to mp3 is greyed out but have not looked into it & besides I have more than enough apps that can make mp3's from waves

The thing is though, with Windows, Mac and Linux platforms there isn't the same pressing need to limit the space used for an installation of an app. Mobile devices could really benefit, however.
I agree, even though I cannot compile for the mobile targets as that's pointless for me due to not having any of them platforms to test what I write, Mobile devices would indeed benefit from the smaller files.
On the same token though it would also be nice to have a "Common ground" so to speak regarding audio. If you are writing a project & targeting just 1 platform then alls fine as just make your media files for that platform. However if you are deciding to target a few platforms then you just have to make sure your music files are in the right format for each of them.
If all platforms could support the same formats that would help, but unless there is an audio subsytem that supports all of them I cannot see another way around it. Also if such a subsystem existed I am pretty sure it would have been implemented into GLBasic.
