Try putting the roms for the 'main' arkanoid (arkanoid.zip)
http://www.mame.dk/gameinfo/arkanoid/
and the roms for the Tayto bootleg (arkatayt.zip)
http://www.mame.dk/gameinfo/arkatayt/
in your roms dir and see if that works.

> - contra

Try this one: http://www.mame.dk/gameinfo/contra/

> - Burger Time

This is a tricky one, and details on how to make a working romset are in my readme.txt (I don't know if Marconelly recreated or included it with his build):

2) take the btime roms and the btimem roms and combine them
into a single zip named btime.zip

For the rest, try getting them from www.mame.dk and most should work.
