About This File
1. About
The project “Soft-15kHz” is about reprogramming of videoadapters and/or their drivers to make them usable with normal Arcade monitors and/or TVs (via SCART RGB <Details>).
It does this by doing small changes to the windows registry to add typical arcade screen resolutions, as well as tweaking some existing ones, and locking out all others.
2. Status
The project is to be considered ALPHA Status but should work as intended.
* Features
o Frontend for Windows 98*, 2000 and XP
o 15kHz Resolutions.
o 25kHz Resolutions.
o 31kHz Resolutions.
o ATI Catalyst supported.
o NVidia ForceWare supported.
o Matrox Drivers supported.
o 3Dfx Drivers supported.
o Intel GMA Drivers supported. (experimental)
o Intel EGD Drivers supported. (experimental)
* only ATI on Windows 98.
* Planned Features
o 35-38kHz Resolutions.
o Other Drivers supported.
3. Costs and Donations
The use of the project is totaly free, however developing is not, as it sometimes requires to buy certain stuff, most likely new or special video cards.
So if you like the program feel free to donate some money.

6. Supported Drivers und Adapters
It should work with any NVidia ForceWare (66.93 and up), ATI Catalyst (2.5 and up), Matrox PowerDesk and 3Dfx Voodoo3/4/5 Driver, which themselfs support a large number of modern video adapters.
Attention! The Windows default drivers are NOT compatible.
Note: The NVidia GeForce 8-, 9- and GTX series require an EDID-Dongle for resolutions below 512x384.
For a selection of tested drivers and adapters please look at this Thread.
