r493 is out and it features support for the Hermes LATEST cIOS. Yeah, you read it right

This is what dimok said:

*Added support for NEW Hermes cIOS (It still might have some bugs so please
report them to me)

NOTE: When you change Global cIOS boot you need to restart for it to take
effect.

NOTE2: Best way of launching games (most compatibility) is avoiding an IOS
Reload by not initializing the network and not have different boot IOS than the
one set in GameSettings.

NOTE3: Know issue: IOS249 boots slower now at the starts. IOS222 boots fast as
always.

You can grab now the latest Hermes' cIOS installer at the download section ;)

EDIT:
r494 is out and added the cIOS223 support too (it's just Hermes with different name :p)

changelog by dimok:

*Added IOS223 support

NOTE: If your loader is rebooting when you try to start a game its because you
initialized Network! Right now initializing the network by trying to update or
trying to download covers/discimages the Loader has Issues with booting games.
Try booting games directly without initializing the Network.
