i think OPL lets hdd spin down if it's not being used during gameplay (e.g if you get stuck in one place and game does not load new data for a while). i've seen it happen in a few games, but i have no issues with it - it just makes a small delay until hdd spins up.Is this fix(HDD Anti-Spindown Fix)that it's on HDLOADER also here on OPL?
i don't think it's the same issue as with anti-spindown fix for hdloader. if i remember correctly it was to make hdl more compatible with more recent consoles. but i could be wrong - haven't used patcher for a while.
if i remember correctly i use mode 1, mode2 makes game lock up after loading save. i'll re-verify that some time later.
