Where to find pin-out resource for making cables

Im hoping to make rj-45 to console cables to use with my MC Cthulhu, for the following, PS1/2, Dreamcast, Saturn, GameCube, Neo Geo, PC-Engine/Turboe Duo and various other systems. I have the PS360+ resource guide and on page 8&9 they offer a diagram to make these cables, but my problem is i dont know what colors the numbers pertain to. Just for an example on the Dreamcast cable the chart shows the 5 Dreamcast cables in slots 1,3,4,7,8 of the rj-45 tip but i dont know what colors those Dreamcast cables are. I know i could just destroy the connection tip of the original console cable but I’d rather not if there is information out there already. If anyone can help me to understand what colors im looking for that would be a huge help. I would like to know all of the cables provided in the PS360+ chart as well as the GameCube, which is a pretty important cable for what Im doing. Thanks for the help.

Colours mean nothing. Different companies can use any color for any cable.
You NEED to test for continuity for each of your wires.

This 100%
Only companies that are consistent with wiring colors are Nintendo, and that only NES and SNES, and that only Nintendo made stuff.
And even then according to Nintendo’s own documents three of the wire colors can be interchanged.

USB wire colors are often wrong too. I Once got a USB cable that Blue, Brown Yellow and Red, and Red was not power.

I gotten cables where every wire was black, and I had to tear up post-it notes to label the wiring till I was done.

Never go with Wire colors, Always go with the Pin assignment/ Pin Location.

Break out a Multimeter, a note pad and start to take notes.

Thanks for the info. I know when Ive soldered them in the past the colors mattered but if its just the pin location that I have. I appreciate the quick response.
