spellfile- even if custom usually only matters when talking about of new custom spells added or modified (your client really doesn't cae if your heal heals 100 points client side and 500 points server side for example) - if you just want to login into a server to take a look around - again won't really matter.
You would only be in real trouble if someone casts on you some sort of buff your client doesn't recognize, or their custom spell has been completely rewritten, that it doesn't include the bulk of standard Titanium spells.
Not saying you can play normally without one, but you could still log in and run around to see whats the server is about before committing yourself to playing there
P99 is different in that regard that you can't even connect to the server unless you have all the right files.
