PSP Go + PSP 3000 Ad-Hoc Multiplayer: Not Compatible

PSP Go and PSP-3000 cannot play ad-hoc multiplayer together.

Why

• Different firmware versions.
• Different internal hardware architecture.
• Ad-hoc protocol incompatible between models.

Alternatives

• Infrastructure/Online: PSN multiplayer (if game supports).
• Remote Play (PSP Go): Connect to PS3 for shared play.
• Third-Party Tools: Unofficial, unsupported, warranty-voiding.

Direct ad-hoc between Go and 3000 is impossible.
