I'm sorry, my attention span isn't that great.
It's an EMS Cartridge.

I finally found the drivers late in the evening yesterday, after running around the house doing thousand different things hahahah

Thanks so much for your help! It is much appreciated!

cheers

Yep. If you're talking about EMS64 USB cart, read my few days old post here:
https://chipmusic.org/forums/topic/2532 … -usb-cart/
and drivers should be here:
https://www.dmgs-r-us.de/downloads/
and I use Windows Flasher Program with MottZilla's Menu from the same link
(It can flash multiple games per cart)

Wait, is it Drag'n'Derp or EMS? DnD doesn't require drivers since they just show up as a USB storage device.

The drivers you linked to are for EMS carts.

ahh! That was my graphycs card in the Original Post....

here is the device manager info for my Drag'n'Derp cartridge:

For some reason it doesn't pop up in windows... No idea what is going on

been trying to find drivers all day, Seems Windows 10 doesn't do the job anymore

Finally found out what to do!

I just found my Drag'n'Derp cartridge on the shelf while helping a friend out
I threw it into my GameBoy Color and everything seems fine.
But when I try
to connect it via USB to my laptops nothing happens. The good old chime sounds
as usually when you plug a USB gadget into a Windows 10 machine. but then
nothing.
So I checked Device Manager and it says: "Uknown USB Device (Set Address Failed)". If I right click and go to properties Device Status reads: This device is disabled. (Code 22) The USB set address request failed.

here is the Information under Events tab (I miss the VID/PID website)

Device USB\VID_0000&PID_0004\6&cc21ac&0&1 was configured.

Hope somebody can help me. It's been super long since I've been tinkering with LSDJ and this cartridge.
