Well I noticed something weird. You would assume that Nintendo's per-game emulators emulate games properly, but it seems this isn't always the case. I have only tested this with Mega Man 4 on 3DS. If you beat a boss you would see the automatic sequence where Mega Man walks to the middle of the room, jumps and then gets beamed away, right? Well, on the 3DS the walking-to-the-middle-and-jumping sequence is skipped. After beating a boss Mega Man appears in the middle of the air (without jumping) and is instantly beamed away. I have checked this with the PSP and everything was good there. So whoever made the emulator, CAPCOM or Nintendo, didn't test it properly. Did you notice anything else with 3DS game emulation? Update: Aparently this only occurs in Skull Mans stage.
