display 10 by 10 tiles but have 30 by 30

[phelpsy]

Does anyone know how i can get the client to display 10 by 10 tiles but have like 30 by 30 tiles if you know what i mean

so basicly you only see 10 by 10 tiles but when u move you see different ones :S hard to explain

Scrolling maps? Kinda like Elysium's?

i think you know what i mean so do you know how i can put it into my mirage 3.77 source ?
