How was it broken in the first place and what did you do to fix it?

the ribbon cable was snapped so i stripped it and it works but there are the columns.

I though about deploying a logic analyzer. What they do (if understand it correctly) is record a sample to the memory (e.g. flash) and then you read it to PC. A good thing would be to know how to build one and use for real time data processing.

Another option is FPGA. The way it works allows really fast signal processing. In fact in can be clocked by the gameboy and still be able to send data to PC. This is what a guy named Snesy did. I tried to contact him through several sources, but without any luck.

Next - Nitro's suggestion to use uC as clock master. I don't understand how (in case of Teensy at least) it solves the issue of only 24 clocks available to do something with the data? 24 is an optimistic estimate.

Finally - DSP. I think logic analyzers are built upon these. However I've no idea where even start with that.

Any other options?

Before diving into the next idea it would be great to figure which of them will (given enough effort) guarantee success. Not some ugly hacked code that will fail 50% of time, but neat and reliable solution. We know it was done on FPGA.

Pros: it will solve this problem, it should suffice to have even more outputs (VGA and composite) and it can be even used as an adapter to plug a controller - so the whole "desktopification" module can be done with one (probably quite big though) board. Since it can have multiple clock domains, and programmed to do virtually everything (no teleportation though).

Cons: Prototyping boards from Atmega (as an example) cost around $80, not only they are programmed in very strange way I can't find any good comprehensive introduction in programming FPGA.

I need to reflect on this... and wank...
