setting up new systems, horizontal and drivin.what should i do 1st?

[G1zm0]

hi guys,but got a pc put together for my cab, a p4 3.4gig, 2 gb mem, 250gb sats drive  and arcadevga 2.

ive installed tiny xp on it, and im in process of putting umpteen dvds od goodies onto it, now the only thing im going to run is horizontal orientated game.

and i also want to put other emus on it.
c64
daphny
amiga
neogeo (unless mame supports al theses roms)
snes
maga drive
n64
pce
and maby
dc,3do,psx


whats the best way to go about this, on my vertical cab ive got mala with vert only roms on it but having a few probs.

should i put mala on this of is there another good fe for it? and about the setting up of the other emus do i need wrapers to launch the other emus or do i need to make batch files?

im going to hide windows (had no luck with the vertical cab doing this, i didnt set a password now its asking for one, ive tryed everything, need to reformat)i tryed the wiki but as explained it screwed up.

do i have to remap buttons for other emus.

now onto another cab im doing DRIVING.

ive a driving force 94 cab, throws up pcb error, so im converting it.
for games like rodblasters ect, what do i do? do i drill holes and install buttons for shoot ect or what, dont know much about racin cabs, im going to put various non 360 wheel  games on it and install modler.
