Soft-15KHz - slim new tool for 15KHz on normal vga cards
gaijin4life:
So I am now operational with a frontend on MAMEPP. THANKS FOR ALL THE HELP with Soft15khz. The hardest part was that I wasn't sure what was supposed to happen after the Soft15khz was installed. Once it was clear that it was installed but not working, sending me off to get a newer Matrox driver, everything fell into place.
For the record, here's the steps to get it running on a Matrox Millennium II:
1. Install Matrox drivers. Version 5.82 is the final version for XP.
2. Reboot.
3. Install Soft15khz by running the program in a writeable directory and selecting the appropriate install (15, 25, 31, USER).
4. REBOOT.
5. When XP comes back up, it should no longer be visible on the computer monitor, if you get "out of range" that's good!
6. If you got "out of range" on your computer monitor after reboot when the windows desktop should have come up, switch the connector to your arcade monitor - it should be visible as a solid image now. If you can still see windows on your computer monitor but not the arcade monitor, you may need to tweak Matrox montior settings. Select the custom controls and UNCHECK "simple controls". Select 640x480x32bit 60hz.
7. Once the desktop is visible, run mame from the command line with "mame - cc" to make a configuration file mame.ini.
8. Edit the newly created mame.ini file and replace "d3d" with "dd" so Mame will use DirectDraw instead of Direct3D.
At that point everything should work!

cabMAME doesn't stretch die image to full resolution as base mame does.

i just used the modeline already in soft15kHz and simply pulled up the pixel clock.

give me 'runtime error 9' subscript out of range

i'll look into it.

bent98 - if you are copying and pasting modelines from soft15Khz/this thread and pasting them into an online converter you need to note the decimal seperator.
I used an online modeline calculator which comes up with an incorrect result if you plug in:
modeline '352x288 17,7kHz 57Hz' 8,25 352 368 408 464 288 289 292 312 -hsync -vsync
as it does not read the 17,7 correctly. You need to change it to 17.7 instead.

Not only a good test device, but also a good project monitor. What are you using soft15 with?

It's my plan to use it as a project monitor once I build a cab (several years in the planning so far...). I've actually got 2, but both need a bit of work and one does not appear to support the full scan range (does 15-17Khz, then jumps to 28khz or so). The other appears to support everything. Sadly I keep them stored away most of the time as they are absolutely massive and ridiculously heavy!
