Would it be possible that someday PCSX2 emulates PS2&PS1 games like dolphin wii&GC

It would be really nice if it was able to do that, most PS1 emulators are jank as hell to either setup, or just in the results they give.

pcsx2 is able to emulate PS1, but not as well as dedicated pS1 emulators (most of them are quite easy to use and emulate most games very well, i wonder where you got problems ???)
comparing it to dolphin is a complete nonsense, though.
because WII and GC are basically the same hardware and architecture.
A Wii is nothing more than an overclocked GC. that's why Dolphin can emulate both (and why wii retrocompatibility was so good)

Interesting point to remember is that Dolphin started in order, and PCSX2 is going backwards. Dolphin started as a Gamecube emulator, and when the Wii released, they basically bolted Wii support on top of it. PCSX2 started strictly as a PS2 emulator and did not pay any attention to PS1 compatibility. The reason it works as well as it does now is because a number of components in the PS2 were literal copies of those in the PS1, however there are a number of finer details that were completely ignored or worked around in order to make PS2 emulation better, that now are causing a number of problems.

In short, it was a natural progression for Dolphin, but is a backwards puzzle for PCSX2.
