I thought save states between levels were OK? If not, then what is this topic for?
Those seem to act like normal saves (having a mode already unlocked and whatnot, then you don't need to load from the save state anymore). I was more talking about stuff like, as a weak example, skipping the "Retry" menu in Sonic Advance between time attack attempts.both
EDIT: further inspection seems to show states that are meant to replace traditional level selects. I don't approve.
What is the difference between having a mode unlocked, having the right Emerald states for S3 ring attacks, haxx0ring 99 lives and skipping entering a level select code? All about saving time, and all give a (non-competitive) advantage over console players; it would be hard enough to draw a line, let alone enforce a ruling.
I have been skipping the retry menu in adv2 for as long as I can remember when I play on PC (obviously not on the console >_>), and I asked if it was allowed first (I also have states for level select codes, emerald states, etc - and I've proved that I'll nuke all stats for any infringements, see S2). It does give a slight benefit in that I find it easier to stay in "the zone" when the turnaround time is less. I seem to remember Taco being against the idea, but the consensus was that it was fine. I also use TAS techniques to work out which routes are the fastest and what I need to do to execute them. These are things you can't do on a console and that save preparation time - but you still have to play the level and execute the strat. If you banned them, I'd argue that for consistency you'd have to ban anything that isn't in the vanilla console game - that includes using dumped maps or watching TAS runs in planning, for instance.
It's worth nothing that I'm plenty willing to share the fruits of my planning labour with people, so I probably end up spending more net time preparing than the people I'm competing against because of these tools (maybe I should stop doing that, I might stand a chance in adv2 then >_>).
Actually, reading this back it seems a little defensive; hopefully you see what I'm getting at and this doesn't come across like I'm a total arse :)
