PlayStation Portal PSP Emulation Patched After Engineers Report Exploit

The firmware update not only fixes the exploit but also unexpectedly improves video quality.

The PlayStation Portal's potential for PSP game emulation was patched out after engineers Andy Nguyen and Calle Svensson reported an exploit to Sony.
The exploit allowed PSP games to run natively on the PlayStation Portal without the need for streaming from a PS5.
The patch, version 2.06, also improved video quality, although this was not listed in the patch notes.
Criticism arose from the emulation community and others who were disappointed by the decision to report the exploit.
Despite the patch, there's speculation about the possibility of other exploits being discovered as the device gets into the hands of more users.
