In the strictest sense: no. Any PSP game can be converted to CSO using tools like UMDGen + CisoPsp or YACC . But Tekken 6 is the where the compressed version genuinely outperforms the original in loading and retains full graphical fidelity. That accidental exclusivity — born from a mix of efficient compression, UMD bottlenecks, and fan experimentation — has given Tekken 6 PSP an immortal second life.
Why? Two reasons:
For on the PSP, using a CSO (Compressed ISO) file is a popular way to save memory, as it reduces the original 816MB ISO down to a smaller size, though it can sometimes lead to slower loading times compared to the uncompressed version. Exclusive PSP Content psp game tekken 6 cso file exclusive
