Ergonomic, split and other weird keyboards

Rules

Keep it ergo

Posts must be of/about keyboards that have a clear delineation between the left and right halves of the keyboard, column stagger, or both. This includes one-handed (one half doesn't exist, what clearer delineation is that!?)

i.e. no regular non-split¹ row-stagger and no non-split¹ ortholinear²

¹ split meaning a separation of the halves, whether fixed in place or entirely separate, both are fine.
² ortholinear meaning keys layed out in a grid

This is the first time I built a keyboard!
A cheapino!
It took a little bit of time to get everything figured out, but I was able to finish that build relatively easily.
However, I am having trouble customizing the layout... I can't load it in the qmk.fm tool and when I upload a json file it gives me something that doesn't match my keyboard.
Also, the encoder currently types 'y' when turned right, I got 2 thumb keys working as spaces and I don't have a modifier key.
As far as I can tell, everything is soldered right, the diodes are in the right direction...
Did I mess up my soldering or is the cheapino firmware buggy?
Any app that can help me flash/customize my keyboard? I'll keep googling.
Thanks!

I might be completely wrong, but I've built my custom based on ideas from cheapino and in my opinion, tompi made a mistake when designing the RJ45 connection. When I copied his design, I ended up with one of the rows connected to ground on the other half. To amend that, I made a custom cable. You can see how he's trying to make it work by adding some bitmasks with functions like fix_ghosting_issue, but it's not a ghosting issue per se, but a mistake in wiring. You can check that with a multimeter running on continuity check mode. I haven't been able to make my keyboard work properly before making a cable with four wires reversed, so that the connection is correct.

Hmmm, that's good to know. I'll check that out with a multimeter.
I was wondering what type of network cable the keeb supports while building it.
Networking cables can either be straight or crossover. I believe 2 pairs are affected by this difference, maybe that's where the issue comes from?
edit: just checked and I have a straight cable.
