Reccomandations for a PS1 emulator besides Duck

Hello,

Recently I got inspired to try Metal Gear Solid because of a friend.
Firstly I tried the game on my Wii which is unplayble.Wii and/or WIISX at fault.
Secondly I went with the Duckstation emu on the family's PC as is listed in the emulation vault but it does not work.:/
I got the d3dcompiler_47 error,fixed that,then 0xc000007b,after which I got stuck because there is nothing really I can do.Cannot update.
(I use a Packard Bell of some sorts,Dual Core Turion - Windows 7)
So onto another emu it is.

Please someone suggest to me an emulator besides Duckstation that is the best I can have for my lappy and could *actually* play Metal Gear Solid well enough.
