Launch the game and press 0 on your keyboard to launch the ROM Service mode, then hit 0 again to access the service menus. Select ADJ (move right by pressing 9, move left by pressing 8, select by pressing 0), then select SPI (standard adjustments). In there navigate to option #18 (game pricing), press 0 to select and 8/9 to change to USA 1 (1/0.25), press 0 to set the option and then 7 repeatedly to exit out of the ROM adjustments. This process works on most SAM-based Stern games. Also, as @Cliffy already mentioned, the SAM navigation keys are referenced in the F2 menu. Thank you, it worked for me, thank you very much
