Changes:

• client:
  • Will no longer overwrite whole recv buffers, only number of bytes received
  • Raise max PDP send block size, now defined as AEMU_POSTOFFICE_PDP_BLOCK_MAX. Ptp send requests larger than AEMU_POSTOFFICE_PTP_BLOCK_MAX should be fragmented before ptp_send on library.
• server:
  • raise max PDP send block size

Client usage:

• See https://github.com/Kethen/aemu/releases on PSP 2000 and up
• See https://github.com/hrydgard/ppsspp/wiki/How-to-play-multiplayer-games-with-PPSSPP#multiplayer-with-a-public-server-on-the-internet-aemu-postoffice and https://www.ppsspp.org/devbuilds/ for PPSSPP
• See postoffice_client.h for integrating with your PSP implementation

Server usage:

1. Install node.js, then run server_njs/aemu_postoffice.js, this is the relay server, requires TCP port 27313 accessible from the internet
2. Download aemu release, Windows adhocctl server can be found in server_win, Linux adhocctl server can be found in dist_660_release/server. Run the server, requires TCP port 27312 accessible from the internet

Docker images with both the adhocctl and relay server are also generously provided by the community:
