How does the capture card interface with the DS hardware?

[jadenham365]

Hello! I am a uni student attempting a project on the DS. I am trying to understand what signal is being sent from the DS and how to use it. The closest resource I can find is from GBATEK which describes the functionality of NDS LCD pinouts, but these codes don't seem to all follow common electrical engineering conventions, nor does it tell me how to use and adapt the signal. This question is directed at loopy, but if anyone else understands the DS hardware I would greatly appreciate it: What signal is being output to the LCD ribbon cable connectors, and how is this signal being captured and used in the capture card?

LDR*, LDG*, LDB* = red/green/blue pixel data.
DCLK = pixel clock.
GSP, GCK, SPL, LS.. = various synchronization signals, I'd recommend looking at them with an oscilloscope/logic analyzer to understand exactly what they're doing.
