This document will explain how to easily change physics and music on different worlds on Super Mario 64 with a hex editor!!! Here you got all the values you need: Haunted House 382E34 [31, 04, 00, 04] Cool Cool Mountain 395FD0 [31, 04, 00, 02] 396038 [31, 04, 00, 06] --Penguin Slide Inside Castle 3CFDCC [31, 04, 00, 01] 3CFEC0 [31, 04, 00, 01] 3CFF98 [31, 04, 00, 01] Hazy Maze Cave 3E6EFC [31, 04, 00, 01] Shifting Sand Land 3FBDF0 [31, 04, 00, 03] 3FBEC4 [31, 04, 00, 01] --Pyramid 3FBF10 [31, 04, 00, 01] --Boss Room Bob-Omb's Battlefield 405E68 [31, 04, 00, 00] Snow Man's land 40EAEC [31, 04, 00, 02] 40EB6C [31, 04, 00, 02] Wet Dry World 41A484 [31, 04, 00, 01] 41A4D8 [31, 04, 00, 05] --Underwater City Jolly Roger Bay 424384 [31, 04, 00, 05] 4243EC [31, 04, 00, 05] Tiny Huge Island 42CB00 [31, 04, 00, 00] 42CBB0 [31, 04, 00, 00] 42CC50 [31, 04, 00, 00] Tick Tock Clock 43760C [31, 04, 00, 01] Rainbow Ride 44A764 [31, 04, 00, 01] Castle Grounds 454C08 [31, 04, 00, 00] Bowser 1 Course 45C2E0 [31, 04, 00, 01] Vanish Cap 4613DC [31, 04, 00, 01] Bowser's Fire Sea 46ACB0 [31, 04, 00, 01] Secret Aquarium 46C2D4 [31, 04, 00, 05] Bowser 3 Course 4780F8 [31, 04, 00, 01] Lethal Lava Land 48D2EC [31, 04, 00, 01] 48D354 [31, 04, 00, 01] Dire Dire Docks 495E00 [31, 04, 00, 05] 495E7C [31, 04, 00, 05] Whomp's Fortress 49E1FC [31, 04, 00, 01] Castle Courtyard 4AF838 [31, 04, 00, 01] Peach's Secret Slide 4B7FCC [31, 04, 00, 06] Metal Cap 4BEB40 [31, 04, 00, 01] Wing Cap 4C2824 [31, 04, 00, 01] Bowser 1 Battle Platform 4C425C [31, 04, 00, 01] Rainbow Clouds Bonus 4CDAE0 [31, 04, 00, 02] Bowser 2 Battle Platform 4CEB28 [31, 04, 00, 01] Bowser 3 Battle Platform 4D1748 [31, 04, 00, 01] Tall Tall Mountain 4EB7AC [31, 04, 00, 01] 4EB818 [31, 04, 00, 06] --Slide part 1 4EB864 [31, 04, 00, 06] --Slide part 2 4EB8CC [31, 04, 00, 06] --Slide part 3 Here is the tutorial: I'm gonna explain it on the Cool Cool Mountain. Cool Cool Mountain 395FD0 [31, 04, 00, 02] That last value (02) is what decides the physics on the level. To edit this, do the following: 1. Search for offset, here it is 395FD0. 2. Now you can see 31 04 00 02, just edit the 02 to any of these values: 00,01,04 Normal physics (Like on Bob-omb Battlefield, I don't know the differences between these 3 values) 02, Snow 03, Sand 05, Water level (Don't really know what's different here from the normal physics!!) 06, Slide level (VERY slippery) 3. Play the game!! How to choose music: I will again explain it with Cool Cool Mountain: 1. A little before 31 04 00 02 you'll see 36 08 00 00 00 08!!! Change that last 08 (or whatever number it is at that level, just make sure it is the 5th number after the "36") into one of the following values: 00-nothing 01-end level 02-SMB music title 03-Bob-omb's Battlefield 04-Inside Castle walls 05-Dire Dire Docks 06-Lethal Laval land 07-Bowser battle 08-Snow 09-Slide 0A-Crash 0B-Piranha plant lullaby 0C-Hazy Maze 0D-Star select 0E-Wing cap 0F-Metal cap 10-Bowser Message 11-Bowser course 12-Star catch 13-Ghost Merry-go-round 14-Start and End Race with Koopa the Quick 15-Star appears 16-Boss fight 17-Take a Key 18-Looping stairs 19-Crashes 1A-Credits song 1B-Crashes 1C-Toad 1D-Peach message 1E-Intro Castle sequence 1F-End fanfare 20-End music 21-Menu 22-Lakitu 2. Now just play!!! This explanation was for the rom file: "Super Mario 64 (U) [!].z64", it works on other rom-files also but the values may be stocked in another order. A good hex-editor to do this is "Gold Finger". Hope you understand my tutorial, I made it so you could have something to mess around with before the release of Toadstool64. No credits for me, I just explained something VL-Tone learned me. All thanks to VL-Tone!!! Tutorial by Jensthecomposer.
