Capcom Arcade 2nd Stadium

For this achievement, you need to obtain 10,000 CASPO in one attempt of either Score Challenge or Timed Challenge. I would say to pick the game you are best at and try getting as far as you can. I found it's really easy getting this playing Mega Man: The Power Battle in Score Challenge. I didn't even beat it (got to the first Wily stage with Proto Man) and finished with 27,000 CASPO. Achievement unlocked!

You'll gain CASPO when you get a Game Over or complete the game and exit the game. The CASPO score is based on the time you played without dying or losing all of your lives or your score in the game. With SonSon, try earning about 50k points without losing too many of your lives as best as you can
