Mickey Mania PS1 autosplitter

//Installation: name this file Livesplit.MickeyMania.asl, put it anywhere you want. In Livesplit, go to edit layout, add -> control -> scriptable auto splitter, and find the file's path. If you did it correctly, you should see some options.

//IMPORTANT: Note that you still have to start and stop the timer yourself. If the autosplitter doesn't work, maybe you are using a different version of the emulator. In this case, you can open Cheat Engine and look for the address of the level indicator value. To do so, open the game, select the process in Cheat Engine, and make sure you activate level select in game.

//Instructions to find the level indicator address and add a new emulator: Press start game and make sure Steamboat is displayed. With Cheat Engine, do a scan for a 4 byte value that has value 0 (first scan). Next, press right on the dpad to highlight Wharf, and search for value 1. Next, highlight Outside Lab and search for value 2. Repeat until it's obvious which address contains the value you need. Double click the address to save it in the address list below. There, double click the address. You will see a window with the base module and offset: for example, doing this on BizHawk gives me address octoshock.dll+3BDB70. This means the base module is octoshock.dll, and the offset is 0x3BDB70.
//In the first state environment below, replace "epsxe" with the executable name of your emulator, and replace the definition of byte level with the following:
// byte level : "base module", 0x###;
//replacing of course the base module and the offset with the ones you obtained from Cheat Engine. If the base module is the same as the executable (as is the case with ePSXe), you don't need to write it.

//Instructions to find the loading indicator address: This address should be exactly 53C greater than the level indicator that you found previously. Try to calculate what it should be with a hex calculator. For example, for ePSXe below, notice that the offset for loading is B3213C, which is B31C00 + 53C. Check with Cheat Engine that the value you obtain behaves as expected: what I know about this value is that it returns 1 while the game is loading (Mickey idle animation loading screen) and that it returns 0 during gameplay, on menus and during cutscenes (including the blue screens with text). If the previous value does not work, then do some scans based on this information.

//If you wish to improve the autosplitter to also start and stop the timer, simply look for some relevant addresses and reach out to me so I can implement them here.
