KH 2.5
-Loads are nearly non-existent, couldn't have asked for better loading situation, it destroys any version of KH2 in loads.
-Game is not very stable. I crashed in 1 playthrough trying to save, Ninten crashed after a fight, someone else I forget also crashed too. It seems far less stable than PS3 2.5 JP so far (not English PS3 tho prob?)
-60FPS is nice, physics are mostly intact, but some side effects are here and there that are very annoying
-Grim Reaper 2 has weird shit going on with his RC on the chest when you have medallions, it kept cancelling on me, didn't test it further (yet)
-Sounds are still missing and such. Only Xigbar's DM seems fixed
-Was having trouble with the Roxas strat, sometimes Roxas doesn't get launched high and recovers before you can keep the combo going. Don't recall this in original 2FM/2.5 PS3
-Could not get Xemnas 1 to crash with Limit Form, same as 2.5 PS3. Needs testing when English 2.5 comes out
-Duck Flare is back to normal in JP, needs testing when English 2.5 comes out
-Could not get Experiment crash to work, every attack during RC was going through me, will test more to see if actually fixed (doubt it)
-Terra is unchanged, however, you can't just single Guard his punch anymore, you get pushed into it due to prob 60fps physics, so you have to double Guard probably
-Terra's key whip start also has a weird graphic that shows now
-Assault Riders don't jump as far now (prob physics problem)
-Only cutscene that seems 60fps is Final Xemnas beatdown, prob cuz part of fight?
-Trinity seems slightly better, maybe due to 60fps, did 328 hits easily on LoD2 fight
-No soft reset still (srsly?)
UPDATES:
-A bunch of people are save crashing now, this is an extremely bad crash to get, you're forced to save often to avoid losing tons of progress
-Vexen Data is fucked now. Anti Sora spawns immediately due to the Data bar getting filled too fast and during the opening scene.
-Something is apparently up with Blizzaga finishers on Axel Data where his RV gets hit now (likely a 60fps effect)
-At PAX, Dean was able to test if Xemnas 1 still crashes in their 2.5 demo. It still exists, but the crash once again does not exist on JP 2.5 PS4
-Forgot this, but yes Final Xemnas RC still drops, just as bad if not worse than PS3
UPDATES (3/10/17):
-Data Org is super fucked (sorta), at least 4 speedrun strats do not work at all anymore
-Axel you cannot Blizzaga finisher him past Revenge Value anymore, he goes into wall...physics problem prob
-Saix corner loop does not work anymore, Explosion does not send him far enough away, so he hits you
-Xemnas 1 Reflega + Slapshot + Reflega + Explosion does not work consistently anymore, Xemnas falls out of Explosion
-Vexen cannot be DM skipped now, due to Anti Sora garbage, his data bar maxes to 5 in like 10s or less of being on you, super fail
-Experiment crash confirmed still exists (though remember, it's in all versions of KH2)
KH 1.5
-Load times still much faster than PS3 version, though not nearly as fast as PS4 2.5.
-Small movement tricks are no longer possible (such as dodge rolling over certain things)
-Infinite Roll Glitch doesn't exist anymore (likely due to 60fps messing with Dodge Roll)
-The Riku Ansem loop has a different timing now, Sora recovers too fast from ground finisher to do it the normal way
-Sound effects are utter garbage now. Finishers sound like smacking someone with paper most of the time, and many sounds don't even play, such as enemy deaths, or Sephiroth hitting you with his Sword
-EXP 0 damage store still intact, fortunately
-Simba Crash still exists
-According to Mist, 100 Acre Woods is a bit messed up now in certain ways idk about yet
-Sephiroth's meteor is now insanely fast due to fps problem
-Sephiroth's Octaslash is screwed up, he doesn't go as far and basically gets stuck on you
