Adplug entry (and all the other with big extension list) doesn't wrap the extension list under Opera.
Outdated winamp input plugins:
64th Note - XMS: 0.08, the newest version: 1.1 Final (AFAIR)
Paragon MGB Player: Those are actually GBC musics, not GBA (though GBA is capable of playing them - backwards compatibility and all).
Nezplug - XMS: 0.9.4.8, the newest version 0.9.4.8+2 (
http://www.vesta.dti.ne.jp/~tsato/software.htmlS98Amp - XMS: 1.3.1+6, the newest version: 2006/01/13 (

There's a new sap player - ASAP -
http://asap.sourceforge.net/. Better emulation quality than in_sap.
VGM plugin was also updated recently - XMS doesn't state the version #, so I can't say if it's lagging behind.
Would be a good idea to replace severly outdated Nosefart entry with NSFPlug (
http://dsa.sakura.ne.jp/index.php?NSFplug) and NotSoFatso (
http://slick.panicus.org/notsofatso.php). Both have the best emulation quality of all the NSF plugins, it's just that NotSoFatso's GUI sucks ass IMO.
//Edit
There's also a new version of Highly Experimental (2.08 vs XMS's 2.07) with *native* support for XMPlay.
