Basic CRT EMU driver questions

(1/4) > >>

Tatas:
Calamity,

I'm not sure I'm doing things properly at this point.  Originally I had some difficulty with TV output that caused me to delay in using your crtemu drivers.  I've now since gone back and uninstalled the latest ATI drivers and replaced them with yours(as well as replacing the CCC with your version).  I then proceed to begin using VMMaker.  This is where I think I have made a mistake.  I changed the VMMaker.ini file so that the Monitor Type variable is set to NTSC.  I felt that it best matched the screen I was using.  I'm using a 27" Sony Trinitron Flat-Screen CRT television hooked up to my PC via Component (RGB cables).  Running Arcade_OSD I see that only around 50 or so modelines have been generated, when by reading the forums here it seems I should be getting around 120.  Should I set it to something else?  Emulation has improved even with the 50 or so lines, games like Puzzle Bobble 2,3, and 4, which used to studder horribly (even though I have a 3.2 GHz dual core WinXP x64 system), now run great.  However games like DoDonPachi, which looked pretty decent at 640x480 (forced by the old drivers) now seem very squished on screen and only take up a very small portion of it.  Please help.  Thanks.

To add a little more info, I'm using an ATI HD4870.  With this card I'm not sure if I need to change from the static dot clock setting that is in the ini file.

Calamity:
Hi Tatas,

Have a look at the Modeline.txt file inside and see how many modelines where created. If the number matches the one you get with Arcade_OSD, everything is fine, otherwise if there are more modelines there it means that the hacked version of Catalyst is not active, and has been replaced by the default one, which only supports 60 modelines.

Attach a log of the ddonpachi game (command line: groovymame ddonpachi -v -md 4 >ddonpachi.txt) so I can see what's happening.

HD 4870 needs no special dotclock settings.

Tatas:
Thanks for the answers.  I'll check this stuff and get back with you.

Tatas:
Ok.  I've checked the modeline.txt file and it only contains 60 modelines.  As you say, the hacked Catalyst driver must not be working.  Any recommendations to get all the drivers stripped off so I can start things from scratch again.  It's very possible that there are remnants of the newer driver still there.
