Reply To: Gamecube with OSSC


625i for 576i and 525i for 480i is completely normal and expected. The console actually sends 625 lines in PAL mode and 525 lines in NTSC mode, as @Paulson explained.

As for the issue with 480p you’re having, it looks like some sort of a sync issue. Does the OSSC itself lose sync or is it actually your television that is acting up? OSSC has a red LED that turns on whenever it loses sync. The LCD also should indicate if the OSSC has lost sync.
