KoF99, how to run it.....?

Hi there!
i need some advice running KoF99.

here the facts:

i use mame32, have the neogeo.zip, and these roms of KoF99:
kof99.zip, kof99a.zip, kof99e.zip, kof99n.zip and kof99p.zip.

these files are missing when i try to start set1:

251-p1.bin NOT FOUND
251-m1.bin NOT FOUND
251-v1.bin NOT FOUND
251-v2.bin NOT FOUND
251-v3.bin NOT FOUND
251-v4.bin NOT FOUND
251-c1.bin NOT FOUND
251-c2.bin NOT FOUND
251-c3.bin NOT FOUND
251-c4.bin NOT FOUND
251-c5.bin NOT FOUND
251-c6.bin NOT FOUND
251-c7.bin NOT FOUND
251-c8.bin NOT FOUND.

for example, KoF95, Metal Slug 2, and AoF3 run without any problems.

i googled the missing files but my spanish sucks hard, so i couldn´t find a solution -.-

i also used the search function without a result for my problem and i red the
"read-this-before-asking-or-we-smack-u-down"-thread aswell

i hope i posted in the right way and broke no rulez

some1 out there that could help me?
(btw, nice site, loads faster and looks better then the rom site i visit normally.)
