I attended my first Colorado Shmup meet at Jon eXidy's place and what an arcade!
I knew his collection was massive after years of being on KLOV and Shmups, but man, it's just awesome.
When I got there, Fire Shark and Raiden DX were in the vertical cabs and I tore into both, playing the Training course in DX and going for distance in Fire Shark. Amazingly, I remembered a lot of the game from my many runs through a few years back and just kept plowing through to eventually get to 10-1 after a good dozen credits - which totally surprised me as I made it through stage 8 and 9 without ever having played them.
I threw in the towel after my 10-1 run, partially because I was kind of monopolizing the cab and mostly because without autofire, it's a bit tiring.
