I managed to get hold of a copy of Cannon Fighter by Moorwood Software on cassette which to the best of my knowledge has not been archived so I have converted it to both CAS and TSX files. You can download it from here. A while ago ago I posted a link for the MSXtra compilation by Alligata but the TSX files were bad, but I've redone them and they should now all work. You can download them from here. You can download the CAS files from here.
