Updating to HyperSpin 1.5.1: The "Files Only" Guide Upgrading your HyperSpin installation to version 1.5.1 using "upgrade files only" is a straightforward process designed for users who already have an established setup. This update is critical for users on Windows 10 (1803 and newer) or Windows 11, as it resolves compatibility issues and introduces new visual features like Animated Wheels. Core Upgrade Requirements
If you are performing an upgrade rather than a fresh install, you only need to replace the following core executable files in your root directory: HyperSpin.exe HyperHQ.exe HyperTheme.exe Step-by-Step Installation Instructions
Backup Your Existing Setup: Before overwriting any files, create a backup of your current HyperSpin folder to ensure you can revert if necessary.
Download and Extract: Obtain the HyperSpin 1.5.1 upgrade files from a trusted source like the official HyperSpin Forum.
Overwrite Root Executables: Copy the new .exe files from the upgrade package and paste them into your existing HyperSpin root directory (e.g., C:\HyperSpin). Choose "Replace the files in the destination" when prompted.
Install the Windows 10/11 Fix: For modern Windows versions, you must copy the win10sxsdll.zip contents (specifically sxs.dll) into your root HyperSpin folder to prevent launch failures.
Administrative Permissions: Right-click on the new HyperSpin.exe, select Properties, go to the Compatibility tab, and check "Run this program as an administrator".
Antivirus Exceptions: Some antivirus programs may flag the new executables as false positives. Temporarily disable your software during extraction and add an exception for the HyperSpin folder before re-enabling. Key Improvements in v1.5.1 hyperspin 151 upgrade files only install
Animated Wheel Support: You can now use .swf files for wheel images. If both a .png and .swf exist for a game, the animated .swf will take priority.
Enhanced Navigation: Added horizontal wheel smoothing and corrected "Up/Down" selection behaviors for letter wheels.
Main Menu Customization: You can now disable specific systems or games from appearing in the menu by adding enabled="0" to the system attribute in your .xml database.
Relative Pathing: Version 1.5.1 allows the use of relative paths for launchers in your .ini files (e.g., .\Folder\Launcher.exe), making portable setups easier to manage. Troubleshooting Common Issues
Launch Failure: If the app fails to open, ensure the sxs.dll is present in the root folder.
Controller Issues: Changes to wheel behavior might require re-mapping. Use HyperHQ to verify your controller input settings after the upgrade.
Missing Folders: If you are transitioning from a very old version (pre-1.4), you may need to manually create a Scripts folder for certain interactive features to function.

Open HyperHQ.exe to confirm your paths (emulators, ROMs) are still correct.
