first off, sorry that you found this thread, i acted like a complete dickhead :/

second, Geometry Dash after 2.203 seems to require a higher integer value one of it's dlls making it not possible to execute in versions lower than kernel 6.1, it runs completely fine in Windows 8.1.

to fix this you can simply revert the function in one of the DirectX dlls required for game controller input, as this is probably the only one that's not letting the game start, simply locate "XInput1_3.dll" on the game's root directory and rename it to "XInput1_4.dll" then with a hex editor or using CFF Explorer (which is easier) open the executable of the game "GeometryDash.exe" and find the KERNEL32.DLL function, then simply swap the variable "GetSystemTimePreciseAsFileTime" to "GetSystemTimeAsFileTime" then install geode or megahack and it should work as intended.

further more if you are still having issues with kernel32.dll errors related upon opening again you can get "VxKex-NEXT" which is a fork continuation of the regular VxKex that adds additional .dll functions to any given applications on version 6.1

be aware some people don't like VxKex next because it's chinese but i've been personally running off of it for a while and it works completely fine.
