Well this site don't host psx isos, you have to download the winzip file, ok I got KOF 97 file, it gives you URLS like this:
http://paginas.terra.com.br/arte/thps32/kof97[www.psxfreaks.com].part01.exe
http://paginas.terra.com.br/arte/thps33/kof97[www.psxfreaks.com].part02.rar
http://paginas.terra.com.br/arte/vstory/kof97[www.psxfreaks.com].part03.rar
http://paginas.terra.com.br/arte/xmenma/kof97[www.psxfreaks.com].part04.rar

after you see the URLS, you have to use a download program that you have to paste the URL into the URL bar, a program that does it is Download Accelerator Plus, or Internet Download Accelerator. Download all the parts of the winrar file, rar it, then you got the KOF 97 iso. Good thing if you used URL download is that the download speeds are great, if you used DSL, you may get 230k per second tops. The place you go is www.psxfreaks.com .The site is in a different words but it kind of easy to understand. Just click on Playstation on the Download section. Then the game, then download the file, unzip it, then open up the text file. It will give you the URLs of all the parts of the game ISOS. Then use Download Accelerator, type in the first URL in the URL bar, then it download part one of the ISO file you what, then when part one is done, open the URL bar again, or add URL, then type in the URL for part 2, etc. It is easy to do it, and you get real ISOS. But you can't add the URL to the Internet explore address bar, only download programs that you download files from the URL.

Note: the KOF 97 URLS are real, just open up Download Accelerator Plus or a other URL download program, go to add URL, then type in the URL for KOF 97, you have to download each URL one at a time, when you are done downloading from the URL, do the next URL, until you got all the parts from KOF 97. Then rar it, and you got the ISO file, then burn the file with a burning program you what, then you got KOF 97 for PSX!
