Changes from u1 (thanks to Knurek, Logiqx, and others for these):
* Mono streams are now panned center instead of left
* Fixed several errors in m1.xml
* Removed tnzs, the clone tnzsj works fine and has the same music
* Added support for the latest NeoGeo sample encryptions, enabling kof2003, mslug5, svcpcb,
samsho5, and samsh5sp
* Removed some non-working testdriver games
* Added pacapp2
* Fixed c74.bin´s CRC

UPDATE: Here is a revised m1.xml file that fixes many issues vs. current MAME and adds some games. Note that pnyaa will not play without a revised executable, but I’m not quite ready to rebuild all 4 versions just for that
