PSX-why downloaded game from here cannot play

I have downloaded legend of mana from here and it is in .rar format. I tried playing it but i cant!!! Someone help me plzzz!

download winrar and extract it, read the tutorial in our tutorials section if you aren't sure. Also, do not use language like 'plzzz', it is forbidden on this forum. Write words out properly.

You can explain your problem more densely.

i think someone just doesn't know about compression and unraring stuff.

It's so easy to do, and it's a common thing you should know if you download stuff, but some people just aren't computer whizzes as other people. So, it doesn't matter, if they get stuck, help them.

i just wonder how he is going to figure out ISOs, mounting and PSX drivers...to me, that seems harder to figure out than compression and file extensions.
