Strangely, I found that the time doesn't stop that normally according to Paraxade0 and sonicandamy. But yeah... the PC version may have the slight advantage over the 360-PS3. I dunno if custom HUD's + Unleashed renderer would affect time. Because I find this very strange compared to the others. Will they invalidate my stats?

The above text is talking about the Perfect Chaos boss battle in Sonic Generations.

I've submitted a stat for Hard Mode and the time cleared was 1:12.91. I don't know if I could get my stat removed or mostly, reverted back to the previous.

If you need to, you can revert a stat yourself by resubmitting it, that's easy.

No idea about the other part though, I don't play Generations

I dont see how it would make a difference to be honest, but why dont you try and beat that time/come close to it just to see whether it does make much of a difference, if you cant even get close to that time with a near perfect run, then you'll know that the Unleashed HUD does give you an advantage.

The issue is that the patch released alongside Project Unleashed causes the timer to stop sooner against bosses.

[SB737]

in that case then, the time would be invalid

I'm terribly late to this topic, as I saw the title and assumed it had to do with a different time saver in Perfect Chaos. I happened across sonicandamy and Groudon discussing this before I took a thorough look. This isn't the first I've heard of mods subtly screwing with the game, and given the anecdotal evidence piling up, it's time for a ban on mods of any sort.

Then is means I need my stat removed.
