Contra III was Treasure. Dunno about SCV4. It's the business, though. I also have a lot more respect for the soundtrack now than I did when I was 12 and wondered why every song wasn't awesome Vampire Killer butt rock?!
TVC 15: You didn't buy it on Virtual Console, did you?
Sadly, yes I did. I bought 2000 points before I flew to PA so I'd have some games to play (my mom's computer isn't an emulation powerhouse, and let's face it, the VC was kinda more convenient). Unfortunately, minutes after buying the points, power went out in WA and I couldn't use them. I hooked up my Wii yesterday, connected to the network, and bought Castlevania, Sim City, and Super Mario Brothers.
I don't plan on regularly buying VC games, though - maybe some TG16 games. If my DS wasn't missing, I would've never bought the points in the first place.
