Anything that uses something other than the SN76489/T6W28 will fail in my player.
That first one you linked to uses the YM2612 (the FM chip found in the Genesis). The following two should work, at least in the second version of the player I uploaded yesterday (pokevgm-4.zip). Keep in mind though that the VGMs need to be uncompressed. Some VGMs are named .vgm even though they're actually .vgz, so then you need to decompress them first, using e.g. vgmtool.
