Soft-15KHz - slim new tool for 15KHz on normal vga cards

[SailorSat]

Hm... Maybe give it a shot without the LCD attached while installing (select a lower res like 640x288 first)

(note to myself, make window smaller )

  Would be a good idea.

tried it that way and nothing. seems like sometimes 640x288 works but I need 640x480. I have only been able to get that resolution by reinstalling drivers then installing 15k then booting up with the lcd and then switching to the arcade monitor. sometimes it shows up as 2 nice looking screens. sometimes as 4 zig zagy screens. Maybe its just my card? If all else fails I can go back to my arcadevga wich works great but I want to be able to run a Sega Naomi emulator and ultimarc's card is way to antiquated.

[androtaz08]

also even when 640x480 is working and I re select in in quick res the screen goes nuts. I have tried every possible way using both the vga and dvi output using the vga adapter.

[gravitone]

is there any way to get soft15khz working yet with windows 7 x64 and an nvidia card? I just need one resolution really (1024x600).

[androtaz08]

ok tried an older driver seems to work a little better. now when it tries to display a res it cant do everything goes black. some of the lower resolutions work. but useless unless I can get 640x480. Maybe I need a dongle? I dont even know what that is. very frustrating. especially when it works by accident sometimes.

[secret80sman]

Guys,
Does anyone have a modeline worked out for 800x600 @60 hertz
and also the 1024x768 @60 hertz or are neither of these possible with Soft 15khz?

[SailorSat]

15khz? not possible
800x600@60 = 35khz and 1024x768@60=48khz
(or 17 and 24 is interlaced)

[secret80sman]

15khz? not possible
800x600@60 = 35khz and 1024x768@60=48khz
(or 17 and 24 is interlaced)

No, 31khz. My 800x600 resolution now only comes up at 51 and flickers where it once didn't and my 1024x768 interlaced shows up as 29 and 30 and also has too much flicker so I wanted to bump up the refresh rate to compensate unless you have a better idea. Would modelines for either of these work? If so could you please post or point me towards where I can get them to cut and paste into my custom31khz.txt file.

I read through posts and you had posted this a few years ago:
modeline '800x600@60p' 40.0 800 840 968 1056 600 601 605 628 -hsync -vsync
 I used it and my 800x600 is back! Any thoughts on how to make the 1024x768 flicker free on a wells gardner d9800?

[FritoFredrik]

so i just made a vga to scart and it workt fine but now when i am running the monitor at 15khz 800x400 and i get flickering in some parts of the screen
and its too big cant see everything its to stretch at top and bottom

need some help tv is a 27" and graphics card is ati radeon 9550 so what setting should i use ? 

[bulldawg]

Ok Ive been trying with no luck to get my setup going. I have a WinFast A340T NVIDIA GeForce FX 5200 AGP vga card. I downloaded the latest build of soft15k and the quick res. I opened soft15k and it said my drivers where not compatable so I downloaded the ones it suggested. Opened soft15k again and saw that it recognized my vga card. So I clicked install and it installed the 15 & 31k s/w. Then I set quickres to 640x480 60hz and restarted my pc and turned on my mtc9000 hantarex monitor and nothing, black screen. I should mention that im using a j-pac aswell. I also tried it on my hantarex polo monitor and still nothing, also tried different resolutions, but nothing works. Any ideas?

1. if your card has 2 outputs, try the other one

2. why 15 & 31khz? both your mtc9000 and polo are 15khz only

[bulldawg]

My card only has one output for vga and a yellow video out for tv. When i opened up soft15k build 48 I think, both 15 & 31k where highlighted, so when I hit install it installed both.

[gse123]

I have successfully got soft1 5khz up and running with a JPAC, and all is good. The only thing is, i can't seem to add custom resolutions... i'm creating a file called custom15htz.txt that contains the desired modeline, and place it in the DIR of soft15khz. Then, I load soft 15, and select 'user' option and reboot... but the new resolution isnt available from the quickres list. Any ideas?

 

[SailorSat]

for custom15khz.txt use the 15khz button.

[gse123]

I already have the 15htz button seected from when i first installed and ran the software. It is now greyed out...

[SailorSat]

Actually click "uninstall" and then "install 15khz"

[gse123]

Great thanks - i'll go give that a try 

[gse123]

Still no joy i'm afraid. Clicked Uninstall, then re-selected the 15khz button and rebooted. Still no new res showing up in quickres list. here is a screen grab of the txt file and contents, just to make sure i've got that part looking ok!

[SailorSat]

I think you have your explorer set to hide file extensions (soft15khz is missing the .exe extension)
so most likely your file is named custom15khz.txt.txt now, try removing the .txt extension

*EDIT*
I doubt THAT modeline will work...
1st your vertical active parameter is wrong (is 334, should most likely be 224)

2nd you have 236 total lines and the should be output at 60hz? 236 * 60 = 14.160, which is way too low for a 15.750 Hz (aka 15kHz) monitor.

3rd.. pixel clock of 12.75mhz? htotal * vtotal = pixel per frame
pixelclock / pixel per frame = framerate
-> 388 * 236 = 91568px
12.750.000hz / 91568px = 139,24?

[gse123]

Removed the extra .txt from the file, and then re-calculated the modeline with another online calculator that I have been recommended (as I tried several, and they all gave quite different results for the same input values?)

Success!   The resultion is now showing in quickres. Many thanks for your prompt replies and great support... not to mention fantastic software!  


*** EDIT: Gah! Even though it is now showing, it will not display correctly. Like I mentioned above, I am a bit lost as to how to correctly work out the modeline, as every caculator I use gives a different (and none working) result.

[secret80sman]

Which online calculator did you use to get things working?

Really need a modeline that will give me 1024x768 flicker free on my WG9800. If anyone has achieved that please post it as well.

Thank You!

[bent98]

Sailor. Mame 137. Can you release your wonderful cabmame 137?

[bent98]

Can you use the Hiscore file from BYOAC? The one you use doesnt disable the disclamer nag screen.

[SailorSat]

I'll look into it later today.
Need to get my 64bit rig updated with the new compile tools.
And I have a new "hack" in the pipe.

[M3d10n]

Just came to post about how awesome Soft15KHz is. I got Windows 7 and an ATI HD 4850 and it allowed me to get 15KHz resolutions on my secondary display, while using 1440x900 on my primary display! Windows 7 detects the secondary display as an "unidentified display", but it offers an option to force the connection in the display resolution settings.

[bent98]

Whats the "new hack" going to introduce?

[SailorSat]

Whats the "new hack" going to introduce?

Actually now there are two...
1. "inputlag"-fix is actually a bruteforce approach to the "input lag" problem. mame now polls twice a frame instead of once.
2. "doublebuff" is the other half of the "new hack". It changes the tripplebuffer to a doublebuffer (and changes the way directdraw handles vsync) which also "could" reduce the input delay.

Its a fact that any form of vsync in MAME causes some slight delay, though I can't really tell why.


As for the S15K topic... Nothing new yet. But some new "stock" modelines will be available for testing soon.

Hey SailorSat,

Thanks tonnes for the new Cabmame Diff's, helps my cab heaps!

I just wanted to ask, the default 640x480i mode line in soft15khz is very, very flickery but the 720x480 mode is nearly flickerfree.  Is there any way to adjust the 640x480 mode line to make it flicker free like the 720x480?

Thanks.

EDIT: 640x480 is the only resolution that seems to flicker.

[SailorSat]

give it a try with

custom15khz.txt

Code: [Select]

modeline '640x480' 13,09 640 672 736 836 480 486 489 525 interlace -hsync -vsync

[M3d10n]

I don't know if it's a side effect of using soft15Khz in a dual-monitor setup, but I cannot make MAME use interlaced resolutions. I can set my extended desktop resolution to interlaced 640x480 or 720x480 if I disable the "hide modes not supported by this monitor" in the Window's advanced video settings, but only 720x480 is listed in MAME and it goes out of sync when selected (progressive?).

Is there a way to permanently get rid of 31KHz 640x480, or fool windows into using the 15KHz mode instead?

Thanks Heaps for that SailorSat, that Modeline looks nearly as good as Progressive

Thanks a million! ^_^

Hm... Some more info would be great.
What kind of monitors? Dual Monitor with a VGA and an Arcade Monitor?
What OS? What kind of gfx card?

Oops, sorry. I'm running a LCD on DVI and the arcade monitor on VGA, Windows 7 64-bit, ATI HD 4850 (10.2 drivers). All progressive 15KHz resolutions work properly and the interlaced ones are there if I go into Window's "list all modes", but MAME always picks the 31KHz ones instead.

Also, if I manually set the monitor to 15KHz 480i via Windows 7 advanced video options and MAME tries to switch to a different resolution automatically , I get the "failed to create DirectDraw surface" error. But this is probably completely unrelated.

[Eric_Adapted]

What is the URL to get the newest Soft15kHz?
I'm using this link http://community.arcadeinfo.de/showthread.php?t=9367
Which shows build 48, is that the most current software?

[codecrank]

FYI, a buddy and I both just setup a mame cabinet using soft15Khz with Nvidia 6xxx/7xxx series cards. It does not work with the latest nvidia drivers.

windows XP + nvidia drivers 93.71  = success

btw those drivers won't works with windows 7.

modeline '640x480' 13,09 640 672 736 836 480 486 489 525 interlace -hsync -vsync
EDIT: I'll be testing a 4890 in a few weeks.

[SailorSat]

Nice

That reminds me...

ATI Radeon HD5970 ... should be fast enough to render AND emulate pacman on the gpu xD

LOL.  Probably enough programmable units on the 5970 to emulate a few games in real time ^_^.

Are you getting a 5970?
