FBA is a good choice for NeoGeo games, KoF 94-99 2000-2003 are working on my Dingoo.
I used FBA Pro ROMs and converted them with fbacache.exe.
Some of the ROMs have missing files, but you will find them on the internet.
I don't remember whether KoF 2000 was one of these ROMs, fbacache output should be checked carefully.
I have now 333 games working on FBA and quite happy
Hopefully Slaanesh will release a speed optimized version (with PAUSE button) soon.
GnGeo would be nice on the Dingoo
It works very well on my Wiz.
