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.
Status
The project is to be considered ALPHA Status but should work as intended.
- Features
  - Frontend for Windows 98*, 2000 and XP
  - 15kHz Resolutions.
  - 25kHz Resolutions.
  - 31kHz Resolutions.
  - ATI Catalyst supported.
  - NVidia ForceWare supported.
  - Matrox Drivers supported.
  - 3Dfx Drivers supported.
  - Intel GMA Drivers supported. (experimental)
  - Intel EGD Drivers supported. (experimental)
  * only ATI on Windows 98.
- Planned Features
  - 35-38kHz Resolutions.
  - Other Drivers supported.
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.

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.

Alpha Build 48 (April 21. 2009)
- Added a donate button to the main window.
Alpha Build 47 (April 1. 2009)
- Registry Access changed to work without batchfiles.
- Default Resolutions of 321 and 401 Pixels Width have been cut down to 320 and 400 Pixels. Old ones still used on ATI though.
- Rewrote Windows 98 Stuff.
- Various Vista Tweaks, however still doesn't work as intended.
Alpha Build 44 (November 2. 2008)
- Experimental support for NVidia on Vista. (only 31kHz yet)
- Various.
Alpha Build 43 (August 13. 2008)
- Various multi-refresh fixes.
Alpha Build 42 (July 24. 2008)
- NVidia "Bug" on XP64 (maybe Vista64 too) fixed. (thanks lettuce)
Alpha Build 41 (July 22. 2008)
- Various small fixes again...
Alpha Build 40 (June 16. 2008)
- Various small fixes...
Alpha Build 38 (February 08. 2008)
- I love decimal seperators...
Alpha Build 37 (February 06. 2008)
- "User" resolutions added. (usermodes.txt)
  Attention! These are added with their real vertical refresh to windows.
- Intel GMA and EGD drivers added. (experimental)
- "doublescan" modelines featured on NVidia and 3Dfx.
- New command-line switch.
  - -ius - installs "User" resolutions.
Alpha Build 36 (September 29. 2007)
- DualHead Features added for NVidia ForceWare and ATI Radeon.
Alpha Build 35 (September 19. 2007)
- Added (another) command-line switch.
  - -nb - disables backup routines. USE WITH CAUTION!
Alpha Build 34 (September 18. 2007)
- Added command-line switches.
  - -s# - selects adapter number #
  - -i15 - installs 15kHz (if available)
  - -i25 - installs 25kHz (if available)
  - -i31 - installs 31kHz (if available)
  - -u - uninstalls Soft-15kHz (if available)
  - -q - quits Soft-15kHz afterwards
    
    So "soft-15khz.exe -s0 -i15 -q" will start Soft-15kHz, select the first adapter, install 15kHz modes, and exit afterwards.
Alpha Build 33 (July 31. 2007)
- Fixed another bug regarding the decimal separator.
Alpha Build 31 (May 10. 2007)
- Fixed a quite simple bug regarding the decimal separator.
- Minor ATI tweaks.
- Added "remove" statement to custom resolution textfiles.
Alpha Build 30 (May 5. 2007)
- Windows 98 support.
Alpha Build 29 (April 14. 2007)
- Now using REGEDIT.EXE rather than REG.EXE. This fixes deadlocks on Windows 2000.
Alpha Build 28 (April 10. 2007)
- Custom resolutions are now possible, for detailed informations take a look into the Frequently Asked Questions.
