Is it possible to get a resolution of 320x240 with an Ati HD2400 and crt_emudrivers on winxp? I have tried to change the DotClockMin at Vmmaker to 6 , 7 , 8 and 8.7 with no success. At best i get the resolution displayed on arcade_osd but when i choose it i get a rolling screen. I am trying to play Am2r at 240p. (i don't have any problem with groovymame and super resolutions)

Even though hd 2400 doesnt support it i used dotclock= 4 so i will be able to view the 320x240 resolution on arcade osd. I generated the modes with vmmaker, installed them and then after restarting i opened arcade_osd
From there i ve choosed 320x240 and by pressing "2" i edit the modeline like seen in the picture. The critical is to use a dotclock= 7.12
after testing i saved the new 320x240 custom. Is working great. I tried Am2r at 320x240 , Project 64 and zsnes at 320x240 and 640x240 stretched, and kega fusion at 320x240. Everything works great. Only Am2r needs first to choose from arcade_osd the custom created 320x240 resolution.
Of course, Groovymame works great as it used before for me.
