I've used PowerStrip to upload it to the dongle.

Hi Sailorsat. Sometime lurker, first time poster.
I'm looking to make myself a dongle to play with, but I have no idea how to get the code onto the 24LC22A chip. You said you used Powerstrip? Do you have any tips or links to check out? Any help you can give me will be greatly appreciated.
And just to check, are the following numbers still correct? (highlighting is mine, to make sure)
--- Quote ---VGA Pins 1, 2, 3, 5, 6, 7, 8, 9, 10, 13 and 14 are wired from the male to the female connector.
VGA Pins 5, 9, 11, 12 and 14 are wired to the 24LC22A.
VGA 14 (VSync) -> IC 7 (VCLK)
VGA 15 (SCL) -> IC 6 (SCL)
VGA 12 (SDA) -> IC 5 (SDA)
VGA 09 (+5V) -> IC 8 (Vcc)
VGA 05 (GND) -> IC 4 (Vss)

And mostly - Danke fur providing the awesome tool and for supporting the community for so long that makes this sort of fun possible!
SailorSat:
Uh... Number should be fine, VSync is indeed connected to the IC and the VGA connector.
VSync is used for DDC1-style transfer of the EDID data (= backward compatible with older cards).
In PowerStrip (entech taiwan) there is a "Monitor" menu, where you can "check" your monitors capabilities.
There is a dropdown with various stuff, like writing a custom monitor driver etc.
In that dropdown is a "update EDID" option.

I love building things, but i can't code very well myself :dizzy:
Vielen Dank, Sailorsat! You must be the most helpful individual on the internet.
EDIT: I'll try editing this post first rather than making a new one... just a bunch of questions i'd like to float, really:
My EEPROMs are on the way! Looking forward to this one. Does anyone if a GTX580 is going to work with Soft15kHz? I can't see it listed on arcadeinfo.de, and using google translate to help my furchtbar Deutsch means i can't search properly :( I also have an older 8800GT to use if needed.
Will soft15kHz work with Win 8.1? Is it likely to work with Win 10?
Is there are Quickres3 tool, and how about for later Win OS? The PVM i'm using would be my 3rd display, on the 2nd adapter. I guess i could just try to re-number the display order and use one of the existing Quickres tools, but i'm curious if there's more.
Finally, for interest's sake alone, would any I2C EEPROM over 2K have worked for the dongle?

Hi, I'm late to the party... still I hope SailorSat is still hovering from time to time.
I bought am EDID dongle to activate my Nvidia 8400M GS.
I have a technical question.
Does the dongle unclocks minimum timings allowed by EDID?
Does it unlock Interlaced modes?
OR, does it specify a list of allowable resolutions?
Hope this get answered someday... :D

help! cant seem to get this to work. I have a evga motherboard with NVidia GeForce 7100 graphics built in, I had soft15khz working in the past but went to the arcade vga. I uninstalled the arcade vga and reinstalled the forceware drivers and then soft 15khz everything looks ok but when running mame and it wants to switch a resolution from what the desktop is running I get a blue screen about nv4_disp.dll error what am I doing wrong? its a windows xp 32 bit with a d9800 monitor.
thanks
