Thanks for letting me know about this one Ponut. It sounds like the events that fade in the screen and put the player in the boat may not have loaded correctly. Please forgive the list of questions, they will help me try and pinpoint what's going on.
• What model number is you Saturn (eg. HST-xxxx or MX-xxxxx)?
• Are you using an ODE, and if so, what kind?
• Does the issue keep happening even after you hard-reset / power-off-and-on the console?
• When you start the game and select "Continue" from the main menu, where does the game continue from - the first cutscene or the white screen?
• If you select "Stage Select" from the main menu and play "Stage 2", does this fix the issue?
• If you play "Stage 2" as a different character does this fix the issue?
• If you start a "New Game", quit straight away, go to "Stage Select" and play from "Stage 2", does this fix the issue?
