As many others have stated, I used to use CoolROM regularly, they were great. I stopped using it for a couple years and when I went back to it a couple months ago wanting to get a N64 ROM. I found out they had all their Nintendo ROMs forcibly taken down by Nintendo of America. Nbd I thought. I downloaded N64 emulator and them immediately went to another ROM site for the ROM of the game I needed. Shortly there after my internet browsers were infected with the browser hijacker Vosteran. HOWEVER, I thought it was from the other ROM site I used. If only I had read these reviews about CoolROM after that.
Fast forward to the other day. I went on CoolROM, downloaded a emulator for the GB Advance, and went to another site to get a ROM(another Nintendo game) Low and behold my browser got hijacked again by Vosteran. In the process of removing it AGAIN I was attacked by something even nastier, this fake, Windows bad image error virus. Just google "bad image error" on Google and learn about what a utter nightmare it is to your PC. I eliminated the problem within 24 hours but it was such a stressful experience that NO ONE should have to go through. Now, this whole time I thought the culprit was not CoolROM, but out of curiosity I googled reviews for CoolROM and found this.
It's appalling this site is still up and running, I am sure many more will fall into this trap because they normally would use CoolROM in the past with ease or heard positive things about it from others. No more, this site isn't what it used to be. AVOID AT ALL COSTS
