Problem with Groovy Mame - Attract mode on Sega Astro

[Delvis]

Hello together

I bought a New Sega Astro City and now a want to use PC as Emu Station.
I use a AMD Radeaon 6450. Mame and Groovy mame are installed. The CRT Emu Drivers as well. As front end I am using Attract Mode.

In VMaker i installed the modlines and if i run AM in window mode - everything seems ok. If i switch to FullSize screen - the screen is doubled.
Cant figure out what i am doing wrong

I will add some screenshots of the picture on the Sega and the Modelines.
Would be great if you guys could help me.

Many thanks in advance

Try fill screen (default). Full screen sometimes has issues. Some commits pulled in git repo today to help wirg sone window mode issues.

Delvis, try this:

 1 - Stop and Disable service: AMD External events utility
 2 - Ensure that the Windows advanced display option is enable: "hide modes that is monitor cannot display"


@keilmillerjr, not sure if you're a contributor to AM. I believe this issue happens with software that sets the fullscreen resolution by a width & height pair of values, omitting the refresh, instead of using the correct width x height @ refresh unambiguous formula. If you allow Windows freedom to pick the refresh, it'll go to 31 kHz most of the times. Stopping AMD's service as described above masks this problem by not making those refresh rates available to Windows, but the underlying issue is still there in the weak mode setting logic inside the frontend/emulator.

Hi guys,

thanks for your reply.

first: fill screen causes the same problem as fullscreen

The AMD External events utility is not installed - at least i cant find it

When i go in Monitor Display settings - I have the checkmark at "hide modes which the moni cant display"

I also can choose between 30khz and 60 - currently it is on 30 with "rowjump"

Look for the service named AMD External Events.  Stop the service and set it to manual or disabled to prevent it from running.  Once you do this, it should stop running the wrong resolution in AM.  Search for Services.msc to find the services manager.

Hi

i do not have it installed. I found the services file but in there, there is no AMD utility at all...

I only installed the CRT Emudriver & CRT Tools 2.0 beta 15 (Catalyst 12.6) for Windows 7/8/10 64-bits. I have Win7(64bits) running and an ATI Radeon6450

today another problem occured: i turned the Win Testsign to "off" - and now i after booting the screen on my Sega stays black...

Help would highly be appreciated

Many thanks

Surprise   

Just curious where you got the idea you can simply turn testsigning off with CRT Emudriver installed.

Anyway, once you reenable testsigning and get things working again, there's something you can test:

- I think AM messes video since it tries to set fullscreen over the current desktop mode (640x480) without specifying the refresh. This causes a 31 kHz modeo to get invoked. This is possible because 640x480@31kHz is a built-in default native mode.

- With that in mind, if you set your desktop to whatever that has no 31 kHz native version counterpart, AM won't probably be able to mess it.

- Launch VMMaker, and in settings/user modes, edit user_modes_super.ini file, and below "640x480@60.000 destkop", add a new line with "648x486@60.000 desktop". Save.

- Generate and install modes again.

- Now, launch Arcade OSD and select 648x486 as your new desktop mode. Lauch AM and see what happens.

I also have this issue with AM and don't have the AMD External Events service (using the older Catalyst based CRT Emudriver on a HD5450).
My workaround was to use windowed (borderless) mode in AM, so it doesn't attempt to change the mode.
