http://www.linuxquestions.org – I just installed Linux ver.6.2 to my Ps3. I downloaded the nasm2.07 and I went to the terminal to try and install it but it won't work. I used "rpm -ivh nasm2.07 and it says there is no such file. I've been reading from site after site for a week now and havn't found any help.My main goal is to get my zsnes collection to work on my PS3 but the terminal said I need NASM.I saw the question for Suze but i'm using a different program. Can anyone help me? (HowTos)
