I'd appreciate if we continue the talk through VMs now, since my PM box is almost full. Anyway, I can help you in the parts you're missing, no problem.
First of all, so far I've only abused for shiny eggs on frame 1 on HG/SS. If you have that option, why would you try for other frame? It's all about being able to hit high delays. With pikatimer, you can hit high delays, or at least learn how to very easily, so I don't see why you don't try to learn it.
As for keeping the roamers, if you don't faint them, you NEED to inform RNG Reporter that they are roaming, as that WILL change your starting frame, and also will help you a LOT to find the initial seed, as there are two methods to do it, roamers and calling Elm. But to be able to do it, as I've said in the previous message, you need to take note of where the roamers are on the moment you've saved (which routes each of them are). And then, when you reset, you also need to take not of where they landed.
