Wow, this is a wonderful thread filled with great achievements and memories!
So, in the spirit of @wongojack’s post…
Back in the day:
Completed The Bard’s Tale (and maybe II as well, but it was decades ago so I can’t confirm the sequel)
Finished Raid on Bungeling Bay (I recall a tip which stated that it’s best to go for the Black & Red factories first, then the Gray factory. This makes the rest of the mission a little easier.)
2016-Present, via emulation (I had to put gaming aside altogether back in 1999 & didn’t return until a few years ago):
Archon speedrun in :57
79,940 in Ms. Pac-Man - It’s not that high of a score, but I find the C64 version to be more difficult than other conversions mainly because I’m convinced that Blinky is on steroids.
1MM on Night Mission Pinball
11MM on Yie-Ar Kung-Fu (which occurred by accident as I figured out a way to beat Blues & ended up playing for 3 hours before I got sleepy & ended my run)
Finished Raid on Bungeling Bay, this time for the TG scoring record
