LAN Play with (PC) PPSSPP and PSP

[barbanium]

In GH, these happen:

PSP-3001 with CFW 6.60 PRO-C2:

I CAN NOT see the character from PPSSPP even in the online list at the top-right corner.

PPSSPP:

I can only see the character from PSP IN THE ONLINE LIST. It appears invisible with a red arrow pointing it.
This only happens IF THE PSP CHARACTER ENTERS AFTER ME. If the PPSSPP character exits then re-enters while the PSP character is still inside, the PSP character WILL BE GONE COMPLETELY EVEN IN THE ONLINE LIST.

The above occurrences happen when the "AdHocSever.exe" suggests the two characters are connected just fine.
Which means I should have typed the correct IP in "Server.txt" from PSP/SEPLUGINS.

Any help?
