Oh my God! The Battle Sim CDs! They rock! ;D I've done about 20 of them so far - the one that caused me the most trouble was the third, or maybe fourth one I did: no. 20, "Let slip the Houndoom". The problem was that I didn't have the sufficiently devious mindset required for the puzzle. I should've remembered that damn Colosseum Double Battle trainer who drove me completely insane by using Toxic on his own pkmn, followed by Facade - which gets powered up to double strength by the pkmn being Poisoned. That was the only one I've needed to look up in an FAQ, so far. (Richard went onto GameFAQs for me, so I didn't read the the solutions for any of the others. Hooray for living with a mad fluffy person.) The rest have been comparatively easy now that I'm thinking about attacking my own pkmn, and I've managed to do quite a few of the three star puzzles on my first or second attempt. I love the Rattata one (no. 17) - level 5 Rattata beating a level 100 Shuckle in 4 moves. Totally rocks! Also, disc no. 35: the Metronome battle! Most crazy thing ever! After five or six attempts where I lost both pkmn while the opposing pkmn were both still ok, I eventually won owing to a stupid collection of luck. First, my Togepi got Recover and almost completely filled his health bar, then the opposing Geodude Transformed into Cleffa, then my Cleffa (on 1 HP!) used Thunder on the Geodude - and because he'd Transformed into Cleffa, it was Super Effective rather than completely useless, then Machop got Confused and knocked himself out. And did I mention the one that involves you having a team of Rhydon, Golem, some bird and Flareon (no. 19, I think, without having the game in front of me), and you have to defeat 3 opponents in 2 moves? The solution is so amazingly devious I don't want to say it in case it spoils it for anyone else, but that one really is brilliant. I could actually live with a complete game of the Battle Sims and nothing else . The rest of the game being good is just a bonus . Anyway, if anyone cares, these are the ones I've done so far & can give solutions for. But obviously, that would be highly spoilerific... 01: Flying Vs. Flying. Predict the opponent's moves to win! 02: Skill Over Power. Use the foe's power to your advantage!
