Download the exe, put it into an empty folder and run it, the updater should download all required files.
Set your paths in the settings.txt file (it will be generated for you).
If at anytime the program crashes, open an issue supplying the text of the "crash.log" file that is created. There may be some features missing that existed before, but bear with me I'll try to get it back into the state that it was before the update.
If you want the program to force an update, delete one of the dlls and it should go into a repair mode.
If you want the program to not check for updates, put a file called "no-update" in the same place the .exe is. This however does not stop the repair mode that happens if one of the required dlls is missing.
When you first launch the program it will say the build in the title bar.
The current version is:
2020-06-07 no. 2 (legacy)
In "cursor data" each cross / plus sign marker indicates a replay frame, both movement and mouse and keyboard presses. Cyan means Key1 is pressed down, magenta means Key2 is pressed down, green means Mouse1 and yellow Mouse2. If more than one button is held it only displays the color of one.
In "press data" markers for cursor movement are omitted and only the lines are drawn. A yellow marker indicates that a key or mouse button was pressed down and was not pressed down previously. A gray marker indicates that a key or mouse button was previously held down but got released. The point of these is to make it more obvious where osu! would register a press and hold.
So this project is actually very old and I don't want to touch the codebase too much. However, during the osu! 20191106 update, they changed the file format of osu!.db, which of course caused this program to break and so I felt obligated to fix it.
The main problem is this project used to use Microsoft XNA, which is obsolete and I didn't have an environment setup to compile, etc. My solution is to port all the rendering to OpenTK + OpenGL.
This does mean that on top of the osu!.db issues I am fixing some other weird scaling issues and changing the way checking for updates works (the old updater was a POS). And while I have a build environment setup now as well as a way to push updates better, I may fix other issues if you bring them to my attention through the GitHub issue tracker.
These are the instructions for Visual Studio 2017+ on windows because that is probably the most common.
(1) clone the repo with git
(2) open the package manager console (from within visual studio)
(3) run Update-Package to install ManagedBass and OpenTK
(4) additionally you are going to need the dll files "bass.dll" and "bass_fx.dll". to be placed in your bin/Debug or bin/Release You can get them from the developers https://www.un4seen.com/ or they are mirrored in the "distro" folder.
(5) build compile run
(6) It may be beneficial to put a blank file named no-update in your
bin/Debug or bin/Release. This will disable all network activity and
prevent the updater from trying to replace what it thinks are outdated
files.
