Faster loading times than of the PS2 version.However unlike the NTSC version it uses the X button to navigate menus, triangle button here goes backwards unlike X and triangle button on NTSC. Has great load times on emulators, on average they are about 7 seconds flat from the time they start loading (Using 4790k OCd to 4.5GHz), faster than on Dolphin (GameCube emulator).(Using NTSC version - SLUS-20718) The circle button acts as a forward button in the menus unlike the X button which you'd expect.The game does not use soft shadowing unlike the other versions, all of the characters' shadows are circular and so are many of the objects and enemies.The game will run at half of the refresh rate of your screen (25FPS if at 50Hz and 30FPS if at 60Hz).Most shaders were replaced by animated textures. For example the path in Grand Metropolis or water in Seaside Hill. Missing most if not all of the shaders.On PAL50 the game has a habit of sometimes doubling a player's input (pressing a button twice when it was pressed once), only happens on real hardware.There's no option for deleting files individually in-game.Body Press + Umbrella and Hammer Down + Bubble in mid-air doesn't give you as much momentum than in the other versions.The draw distance of robot despawning and respawning is much shorter compared to the other versions.The loading time after choosing a team in the menu is faster than in the other versions.In Frog Forest as Team Chaotix, there are objects in the center of the small plateau holding CP1 that replace a certain sprite seen in other versions.Time Stop after effect of Team Dark's team blast doesn't last as long.Sometimes where a lot of rendering is required or particularly in 2P mode the framerate drops.Slowest of the loading times on real hardware.Strange graphical glitch with the Flight Gauge."Continue without saving" and "Saving" text boxes stay on-screen longer.Strange musical track repeat at title screen (Son-onic Heroes!).Spatial sound mixing - similar to the PC version when "3D Sound" is enabled.Higher-quality FMVs than the other versions.Metal Madness/Metal Overlord are noticably shinier than the Gamecube or PS2 versions.For example the path in Grand Metropolis. This allows you to do the Early Start glitch more easily than in other versions.
