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!!! Change that 08 (or whatever number it is at that level) 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.
