MAMEWorld Forums - EmuChat - Scanlines mame 0.145

Hi all i'm new to mame and had a general query if someone would be kind enough to help me out as it's driving me insane. Iv'e been using mame32 which i had issues with screen sizes etc everything either looked stretched or really small but i loved the scanline effect for authenticity as im using an lcd monitor (cant afford an arcade monitor) and in mame32 it was as simple as ticking a box. Now im using mame 0.145 and can't find anyway of turning scanlines on. Iv'e been told it's in my mame.ini file but can't see where i need to put or adjust it so any help would be greatly appreciated. Thankyou for your time and patience with a newb in advance
