actually it isn't bad at all. One only needs to hit the correct second...which is EASY!!! So, not being able to initially verify your seed is no big deal. I would know...I have RNG'd about 100 Pokemon without being able to verify my seed.
Edit: BUT, people are working on getting a workable AR code so this can be done.
This AR code is done and has been done. The MTIVRNG Check code. But if you're doing non-C-Gear you really don't need it. You'll hit your seed almost 100% of the time. And you shouldn't be using an Action Replay with non-C-Gear anyways.
