Hello
I have long been trying to run a HD5770 with Groovymame and Powerstrip.
I manage to get customs resolutions with EDID override using CRU tool:

The problem is that we can add only four non-standard resolutions on EDID. This is not enough to have a perfect screen with MAME.
Powerstrip is able to change the timings with Groovymame but you still to have some resolution created at least for the different heights.
Is EDID dongle can do something for me, or is it useless (it seems unnecessary for ATI cards).
Can we add more modes in the EDID override or can EDID dongle does?
By installing soft 15kHz, I can see all the added resolutions but when I try them, only those in the EDID override works, others use resolution nearby.
This is definitely a EDID problem that prevents to have all the resolutions.
Can This Be hacked?
