From Team Omega:

He was recently published a custom firmware made by a Chinese programmer
that despite being a 5.02 removed support for ISO / CSO.

So we decided to release our version of 5.02. We hope you enjoy it,

Update:

1. Put the files included in this package in the folder UPDATE
2. Place the EBOOT OFFICIAL 5.02 in the UPDATE folder renamed to 502.PBP
3. Launch the application and follow the steps

CHANGES:

- UPDATED core 5.02
- Again support for ISO / CSO
- From new support for PSX games

BUGS:

- Sometimes the pops does not work properly, if you're a player mostly recommend PSX
which continues in 5.00 M33-4 or the 3.95 GEN But try this version because a lot of people who
our version is proven to work correctly.
