Contra is too difficult without the cheat (maybe with) and with the cheat you get no achievements.
Frogger is OK but after 10 minutes you've had about all you can take.
I'm really glad I didn't purchase this one, its a good evening on gamefly though. Playing through Symphony of the Night is the best part of this disc. So if you're not interested in tossing several hours into that classic this disc is mostly a waste.
I did rack up the easy achievements on all 3 though ;)
This wasn't a bad rental. I got it mainly for Castlevania and was pleasantly surprised with the number of arcade trial games. There was UNO, street fighter, and pac man to name a few. Worth a rent for something different
In my opinion this is the better of the two Konami Classics discs, but that isn't saying much. In theory the Konami Classics sound fun but they will likely only hold your attention for a very short period of time.
The most annoying factor is that the games are played on a small screen with borders around it (at least playing on a widescreen TV) which is unacceptable.
Frogger is fun for a few minutes while Super Contra is quite challenging (but in my opinion inferior to Contra which is on Volume 2, however considering it too is played on a miniature screen it's not worth playing).
Castlevania: Symphony of Night, however, is the best game on both Konami discs. The Playstation game looks wonderful and plays great to this day. Unfortunately, once again the small screen is a hindrance.
I'd rate Castlevania a 9/10, however the disc as a whole is pretty useless.
