Is 3.90 m33-3 a good custom firmware ?

[marcanb28]

It's been 2 years I haven't played with my psp but I wanbt to play again.

Mine also has the custom firmware 3.90 M33.

I had many .cso and .iso games and it worked great.

But I wonder if new the .cso .iso games released recently would also work on this old firmpware or if I need to uprgade a new firmware.

If it's aviced to get a new one, which one to chose please ?

that firmware is incredibly old....but other than that it is decent
