I need to make sure the information is accurate. Let me double-check: The Vita's native PS1 emulation is possible without PSPEBOOT, but for other systems, custom firmwares like PSPEBOOT might be necessary. For PSX games (which are actually PS1 games), if the user wants to play Tekken on Vita, perhaps they are referring to playing Tekken on PSX via Vita using an emulator. However, if the Vita can run PS1 games natively through firmware modification, then maybe they don't need an emulator. But if they are using PSPEBOOT for other reasons, maybe they want to use an emulator setup to run PS1 games on a modded Vita. So the user might be conflating the Vita's native PS1 capability with the use of PSPEBOOT. Maybe I should clarify that difference.
