A Japanese user by the name of ‘Yuki-mi’ made a plug-in that allows a Custom Firmware (CFW) PSP to connect to Kai via its USB connection ONLY, completely removing the need for a dedicated wireless adapter. I tested the plug-in with two games, Monster Hunter Unite and FF Dissidia, but I still encounter freezes with Dissidia. I'm assuming that this plugin is still work in progress since it's not fully stable yet.

This should work on all PSPs 1000/2000/3000 5.00 m33-6/5.03 GEN-C/5.50 GEN-D3/5.03 Prometheus/5.50 Prometheus.
