I found a link on a dusty forum promising a "Direct PS2-to-PS3 Conversion PKG." I downloaded the 2GB file, transferred it via FTP, and watched the progress bar crawl. When I finally launched it, the PlayStation 2 logo appeared—a good sign! But then, the screen went black. Total silence. The console didn't crash, but the game refused to breathe. The Lesson:
For the Tekken 4 PKG to function on a PS3 console, the system firmware must be modified to bypass the DRM checks. Standard Official Firmware (OFW) will not run user-created PKGs.
