Omegadrive, questions about 2588 and off-breed resolutions..

Magneto

Hello,

First off, I'd like to thank you for your great drivers. I'm currently using the 2.5.88 drivers under Win98SE, and they're working fantastic. I just ran into my first problem today after no problems with 10 games I've been testing.

Question: Is there a safe way to disable or remove some of the non-standard resolutions that your drivers installed? I'm having a problem with a sim, Jane's USAF. After it ran it's test of my 9700, I noticed I'm only able to select a res as high as 1280x768 (32 bit). ALL the non-standard resolutions are listed, and I'm thinking that USAF might only allow so many resolution options. I used to be able to select 1280x960, 1280x1024, and 1600x1200-32 with my older GF2 GTS 64. Here's the resolutions it's listing:
640x480 (16,32)
720x480 (16,32)
720x576 (16,32)
800x600 (16,32)
848x480 (16,32)
960x720 (16,32)
1024x768 (16,32)
1152x864 (16,32) <-- this is the last "standard" res I can select.
1200x900 (16,32)
1280x768 (16,32)

These appear to go right up the list of resolutions in my display properties. I don't use 1/2 of these, so I'm wondering if by disabling/removing some, I might get the higher resolutions to show in USAF. I've looked high and low for a config file in the program, but I just cannot find anything.

Thanks for any ideas..

Unfortunately there are a number of lousy programmers that use the "first # of resolutions avaiable" technique, and those games, when I add the extra resolutions, bump the higher resolutions out of the list, and that is exactly what is happening here.

To fix it you'll have to do some INF mod...
First open the INF file (backup the file in case you mess anything) included with my drivers, now look for this line:

; ---=== Video Modes Settings Added By Omegadrive (For All Cards) ===---
HKR,"INFO\INFO\DAL",DALNonStandardModesBCD,..etc
HKR,"INFO\INFO\DAL",DALDTMCRTBCDxxxxxxxxxxxx...etc
HKR,"INFO\INFO\DAL",DALDTMCRTBCDxxxxxxxxxxxx...etc
HKR,"INFO\INFO\DAL",DALDTMCRTBCDxxxxxxxxxxxx...etc
HKR,"INFO\INFO\DAL",DALDTMCRTBCDxxxxxxxxxxxx...etc
HKR,"INFO\INFO\DAL",DALDTMCRTBCDxxxxxxxxxxxx...etc
X************************************************* *************X

In the marked line (X*X) above you will insert this string (in one straight line, the thread divided it in four):

HKR,"INFO\INFO\DAL",DALRestrictedModesBCD1,1,07,20 ,04,80,00,00,00,00,07,20,05,76,00,00,00,00,08,48,0 4,80,00,00,00,00,09,60,07,20,00,00,00,00,12,00,09, 00,00,00,00,00,12,80,07,68,00,00,00,00

That will disable most custom resolutions up to 1280x960, now save the file and re-install the drivers, voilá

Omegadrive,

Thanks a bunch for getting back to me so quickly. I'll try the fix in a short while, and let you know how it goes later. I'm going to assume it's best to uninstall your drivers before reinstalling them? This is my first run with your ATI driver versions, and I wish I had installed them long ago. Perhaps this would be a good time to try your Cat 3.4s? I would think the same fix would work the same with them.

Problem solved..

I went ahead and modded the 2.5.99 drivers and upgraded to them. After a new test, the game now recognizes and allows the higher resolutions I was looking for. I now have two versions of Omega drivers, with or without the custom resolutions.

Omegadrive, a sincere thank you for your help with this. I appreciate it.
