The contest achievements were annoying but with the right strategy you can knock them out quickly. Catching them all in one game is basically the same as catching them all in any other version so I'm glad I didn't have to do it again this time.
Like others mentioned, I appreciate that it was complementary to the Ruby set and many of the achievements were not repeats. Overall this was a pretty interesting achievement set. My final In-Game time on my main save file was 116:51 although I made two other save files to help speed up the process of winning the lottery.
Mastered! According to RetroArch this took me 37:16 in real time to complete.
