These games are OK, well tolerable anyway. They appear to work fine on a CycloDS. I played 3 missions on each version so far.
I can't help but consider them a sort of a rip-off though. They could have put both versions on one cart and just let you choose which side to play as at boot up instead of forcing people to buy the same game twice. Could make the same complaint about Pokemon, Megaman and other franchises that have pulled this little scam.
I remember making this complaint about the older Transformer games on NSider when it was still up. The post got deleted. I guess they didn't like that idea being put out there much.
Of course, it's all moot anyway since I have plenty of room on my flashcart for both of them.
These are the first games in quite a while that I might actually play on the DS, even if they aren't all that great. Because they aren't all that terrible either. I haven't decided whether I prefer this or the Autobots version yet.
