International Topic

[FunkyCoch]

Hallo leute,

Here should I stop my German Knowledges
Yesterday someone from a french forum inform us about your project.
I spent my complete morning to read all the topics out there to be sure of what your project was dealing with.
First of all I must say it is absolutely amazing to see all your work and explainations, even if I wasn't able to understand in deep.

As your tool is quite a revolution, I think many people worldwide whose german skills aren't that high will ask you many questions about soft15K.

It maybe useful to start an international topic or section in order to open your work to the international audience and for sure get additional support and testing help from the whole world.

Thank you for wasting your time reading this.

Thanks for your feedback.

I'll add an english version of the topics soon.

[FunkyCoch]

Thank you for your answer.
Many eyes are spotted on your project for a few days
We are following your progress with attention
Despite the fact i don't have a correct setup yet to test your work.

This looks great! I'm hoping to test it out this week. I have one question though:
The FAQ says that Soft-15KHz works with ATI Radeon cards, but will it also work for older ATI Rage cards?

I like to use old Dell Optiplex computers for my MAME cabinets because they have on-board ATI Rage graphics that work very well with AdvMame and arcade monitors in DOS.

[SailorSat]

Sadly it won't.
The Rage128 drivers do support my programming, however, they don't support custom resolution.
Rage XL and RageIIc drivers don't support either.

[JoyMonkey]

I'm trying to make a custom resolution for Robotron and Joust. These games run at 292x240.
I don't completely understand the "Formeln und Grundlagen" thread, so can you tell me if I'm right here?

Horizontal:
H_ACTIVE = 292
H_TOTAL  = 292 / 0.73 = 400
H_START  = (0.73 + 0.09) * 400 =  328
H_END    = (0.73 + 0.09 + 0.09) * 400 = 364

Vertical:
V_ACTIVE = 240
V_TOTAL  = 240 / 0,92 = 261
V_START  = (0,92 + 0,01) * 261= 0,93 * 261= 242
V_END    = (0,92 + 0,01 + 0,01) * 261= 0,94 * 261= 245

Number of pixels = 400 horizontal pixels per line * 261 vertical lines = 104400 pixels per frame

PIX_FREQ = 104400 pixels per frame * 60 frames per second = 6264000 pixels per second = 6.26MHz

Modeline <NAME> <PIX_FREQ> <H_ACTIV> <H_START> <H_END> <H_TOTAL> <V_ACTIV> <V_START> <V_END> <V_TOTAL> <OPTIONS>

Modeline "292x240@60" 6.26 292 328 364 400 240 242 245 261 -hsync -vsync

Is this right? I'll try and test it out tomorrow night, but to be on the safe side I'd like to know if I got it completely wrong.

[SailorSat]

yeah that should do it.
you got a typo there, but the calculations are right.

Horizontal
Active = 292
Total = 320 / 0.73 = 400

also, you could try lowering the horizontal sync width a bit.
this would look something like this.

Modeline "292x240@60" 5.88 292 304 336 376 240 242 245 261 -hsync -vsync

[JoyMonkey]

Thanks for spotting my mistake, I fixed the typo above.

Why would I want to lower the horizontal sync width? How did you calculate those values?

[SailorSat]

no specific reason, I used 0.8 instead of 0.73.
but that differs from screen to screen.
it may be you get some black borders to the left and right of the image, thats why

[JoyMonkey]

I tried both modes (using the 0.73 and 0.8 values) and it looks exactly the same each way.
The mode didn't display correctly using my GeForce cards (the picture doesn't use the full horizontal width - see attached).

Then I tried my Radeon 7500; everything looks much better with this card and the custom 292x240 mode works perfectly!

hey ! your job is Great

I have test your prog on my cab and it works great but i have a problem with the Verticale synchro of the monitor (an hantarex polo 20"). I couldnt set the V sync and its strange because on dos (with advmame and advmenu), the v_sync is Ok and i have no problem to set her.

My config:

- Windows XP pro sp1
- Radeon VE DRR
- lastest ATI driver
- your (wonderfull) prog

Have you an idee ?

thanks, your prog is Great !

[SailorSat]

Mhm...
What Version of MAME do you use?

As far as I know, AdvMAME does NOT support vsync in windows.
With normal MAME (or MAME32) just enable "tripple buffer".

Should work then.

[pierrick]

Hi thanks for your response.
In my mame cab, I use advmame,advmenu on DOS witch arcmon.sys driver.
With this solution, the V_sync on the monitor is OK and I'have no matter to set it.

When I test your great prog, I couldn't set the V_sync. When I try to regulate it, as finely as possible, the v-sync rols slowly uninterrupted and coulnd'nt fix.

thanks

[SailorSat]

Hm... That's strange...
How is your monitor wired up? Are you using a J-PAC?

Soft-15kHz should output negative (seperated) H- and V-Sync so you need to connect both on the VGA side (or twist them together for C-Sync).

Works fine on my Polo 25"...

I really wonder because it works in DOS...

[pierrick]

yes it's strange and an other personn as the same probleme on gamoover.net
(french arcade forum).

Yes I use a JPAC between my computer and my PC and someone tel me that I must use the same MODELINE on windows that on DOS but I don't know what is it.

bye & thanks
