Instead of downloading "highly compressed" installers (which often contain malware or broken files), use the following legitimate setup:
: The emulator requires a PS2 BIOS file to run, which must be dumped from your own PlayStation 2 console. Why Avoid "Highly Compressed" Downloads?
: Files claiming to be "30MB" or "500MB" for a game that is originally over 4GB often use fake installers to bundle viruses or adware.
: The latest release with high-end graphics and full online support.
: You will need a Tekken 5 ISO file. Legally, you should create this by "ripping" the data from a physical Tekken 5 PS2 disc that you own.
