So, I finally got time to implement my idea: revision 3bd9654 is a first draft to support more than 2 Jpcsp instances for applications communicating through Adhoc network.
I've added the command line option "--localIPAddress 127.0.0.X" to specify the local IP address to be used. It has to be different for each Jpcsp instance. E.g. use 127.0.0.1 for the first instance, 127.0.0.2 for the second instance, 127.0.0.3 for the third instance, etc.
The network settings of all the instances must enable ProOnline and specify "localhost" as the ProOnline MetaServer.

The implementation is not yet very user-friendly as you need to use command line options, but this is just a first draft to verify that my idea is working at all.

You probably will require a quite powerful PC if you want to run 3 instances or more Wink

I'm waiting for feedback Wink

When reporting don't forget to post the log files of all the instances.
Always include a complete log file at INFO level in your reports. Thanks! How to post a log

The same support has now been added in b2e8188 to "LAN Multiplayer" as well.

I've introduced quite significant changes in 21afc00 to try to improve Adhoc networking with multiple Jpcsp instances on one PC. Could you please test it?
This change could break games which were previously working, so regression testing with different games supporting Adhoc networking would be much appreciated Smile

Thank you!
