Finished main storyline for Kingdom Hearts Re:Chain of Memories HDI should warn you about the loading times in KH2. On the PS2, when you go into a drive form, Sora immediately goes into that form. However, in the 2.5 Remix, it takes a while (~2-3 seconds). It affects the gameplay because while you're waiting for Sora to transition, the enemies around you are still moving. A workaround people came up with is whenever you go into a drive form, you pause the game for a few seconds and then, resume into the game.
Playing the Reverse Rebirth - man this game is so repetitive (Chain of Memories overall) - cant wait to play the superior KH2 and BBS HD.
