// Towerbolt Autosplitter
// Author: hyperbola0
// version 1.3

// CHANGELOG:
//
// version 1.3
//  - Added a setting to split when entering any level from main menu. 
//  - This will store the current file time in a variable and use it to read accurate split times. 
//
// version 1.2
//  - Supports Towerbolt 1.00.01 and Towerbolt 1.00.02
//  - Implemented in-game time for Towerbolt 1.00.02
//  - Fixed the method of game version checking to hash the data.win file instead of the exe
//
// version 1.1
//  - Implemented game version checking to support multiple versions
//
// version 1.0
//  - Auto-starts when game transitions from room 5 (main menu) to room 6 (F1)
//  - Auto-resets when game transitions from any room to 5 (main menu)
//  - Auto-splits on game end (leaving F160)
//  - Option to auto-split on each block (floors 19, 54, 73, 107, 124, 155)
//  - Option to auto-split on each floor
