Well, In 4th Gen your game hates you more. Let me explain.
In BW, your seed can be in the earlier part of the second, or in the later part of the second. You have to check this out on your own. This also depends on the seed itself. You have to feel it.
In 4th Gen you have to hit precisely target 1/50 of the second.
What did you say about the game hate?
