PSP Game Sharing SOCOM: Fireteam Bravo 2? Impossible (UMD Hardware)

No game sharing possible for SOCOM: U.S. Navy SEALs Fireteam Bravo 2 on PSP.

UMD Format: Physical disc. One disc = One console at a time. No install-to-internal (only 64MB cache).
No Account Linking: PSP (pre-PSN unified) ties saves to Memory Stick, license to UMD. No "Primary Console" / "Gameshare" like PS3/PS4/PS5.
Ad-Hoc Multiplayer Only: 2–16 players via Local Wireless (Ad-Hoc). Each needs own UMD. GameShare (1 UMD → 3 clients) exists for some titles (e.g., Monster Hunter, Patapon), but SOCOM FTB2 does NOT support GameShare.

Buy 2 UMDs (Cheap used ~$5–10 each).
CFW + ISO on Memory Stick (both PSPs) – Piracy / Legal Risk. Requires same region ISO.
PPSSPP Emulator (PC/Phone/Deck) – Netplay (Ad-Hoc Server / ZeroTier) – Best experience (HD, 60fps, save states, cheats).

For legit local co-op: Two PSPs, Two UMDs, Ad-Hoc.
