1 Credit Clear of Sega's 1997 arcade game, The Lost World: Jurassic Park played on the default difficulty and life settings (3 life start). I let the intro sequence play after the end of the game then used the service and test buttons to show the settings that were used.
I played this with a Sinden Lightgun using the the Supermodel emulator for Sega Model 3 games (specifically the version was Supermodel SVN r807). The game has been upscaled to my monitor's resolution of 2560 x 1440, but I kept the aspect ratio to 4:3 to be as close to the original experience as possible (the emulator is capable of 16:9 presentation without stretching out the image). The ROM set was "lostwsga".
It took a lot of practice to get this clear, I didn't think I would pull it off in this run, but I managed to beat the final T-Rex without getting hit and was left with a life to spare even. The game gives a few life-ups for saving certain people and for collecting 3 "powerbar" items. I managed to miss the second powerbar in the game which means I missed 1 extra life I could have had because there are only 6 powerbar items in the game. Overall, I'm very happy with this run.
