Missing 3 Unlicensed GBA Roms

System: Game Boy Advance

Advanced Music Player, Bounty Hunter X, and Chopper 2 The Return. These are three games that I'm currently missing from my GBA collection, scanned with the latest .dat file from DAT-o-MATIC. I can't find anything about these games, and all the .dat tells me is that they're all unlicensed and released in Europe. If anyone could help in the search, that would be great.
