Hot Shots (Everybody's) Tennis: Get a Grip

[Sablicious]

I have tried to get this game to hook up via ad hoc LAN -- on separate, local PC's, and on the same PC (using this method)... But, have had no luck.

The furthest I've gotten is:

• creating a lobby ("Club House") with the host player, with the second player unable to find the lobby (*the host cannot interact in the lobby, only hard reset the emulator from there... so, I'm unsure as to whether the lobby is created proper)
• the game locking up at the "Initializing Network" prompt, just as the lobby is being created (*this tends to happen when using a single PC, via the 127.0.0.1 loop-back method)
• tested with 1.6.3, 1.7.4, 1.8, 1.9 and 1.9.3 builds
• tried different port offsets "0", "5000", "8000" and "8800"

So, is it possible to play this game via LAN-- either through two, local PC's plus router, or even on a single PC? Or, is Hot Shots / Everybody's Tennis: GaG not yet compatible with PPSSPP ad hoc multiplayer...?

(thanks)
