Primal Rage (USA) // SMPC bug - Cannot boot #74

Closed Zet-sensei closed 5 months ago

Zet-sensei commented 5 months ago

The game refuses to load on my systems (Single and Dual RAM). I tried to force a region, multiple BIOS versions.

The game goes back systematically to the BIOS after the SEGA logo, but detects the disc as a valid Saturn one inside the BIOS menu. Even with a full fresh reboot of the core and the MiSTer system.

EDIT : I asked for a comparative test with other users, as the game booted up on previous builds with just a broken intro FMV. Searching eventually for a regression.

EDIT 2 : Kuba-J tested the game on Discord & could report the game tends to boot for a first time, and same result as mine when trying to launch the game once again on his system.

In addition.

The JPN version boots, but no controller response at all on that version of the game.

EDIT : I've asked for a comparative test to other users on Discord & will update the issue if necessary.

I've seen a note on Mednafen 1.28.00 that should give us a hint about the problem.

Seems to be related to issue https://github.com/MiSTer-devel/Saturn_MiSTer/issues/76

October 5, 2021:
    SS: Implemented a delay when the SMPC joystick read process is aborted due to time over or due to the Break bit being 1, per tests on a SS, and fixed
    timing granularity issues with the processing of the Break/Continue bits; fixes unresponsive input in "Discworld", and abort to CD player screen in the
    USA and Europe releases of "Primal Rage".
