I had Intellivision as a kid, so I'm familiar with most of these games. I had over 70 games for INTV back in the day. Too bad we couldn't get some of the Imagic and Activision games in this compilation, many of those were among the best the system had to offer. I'll be honest, a lot of the games in this compilation royally suck, but there are some gems, such as the D&D games and the Intellivoice games, as well as a few others.
This compilation is definitely an acquired taste. Many gamers may not appreciate this old-school stuff. Me? I love it! I have a PC INTV emu, but you can't really play the ones that use the number pad very well when you're fumbling between the keyboard and a controller, not to mention not being able to see the overlay graphics while actually playing, only before you start the game. On the DS, all your number pad keys are labeled right there as you play, which makes it much better than other versions of INTV for other systems just in the control department alone.
I've noticed while playing some of the games that the sound is not perfect....it plays slightly slow. Some games are worse than others, but the aberration IS noticeable for anyone who may have played the original console. I also noticed some speed issues on a few of the games. And the slowdown is in weird places....like in menus and stuff. It's NOT perfect emulation. In fact, I think this may be a lot like the Sonic compilation in that it's only partially emulated, and part rewritten code.
I bet some talented hacker could do a better INTV emu than this on the DS. Don't get me wrong, the games ARE fully playable, it's just not 100% faithful to the actual console.
EDIT:
There is missing voicing in Space Spartans. When you're in a zone, you should be able to hit the "number of aliens" button to get a count, but all it says is "aliens", it never tells the number. It also doesn't tell you your energy level....it's supposed to say "energy level low" and stuff like that, but all it ever says is "energy level". I tested this on the ROM and my retail cart.....no difference. I mean, come on! They had over 5 years to perfect this and didn't catch something like that? Geez....
