Add link to fixed KiCad version of DMG-CPU B chip schematics #238

Closed msinger closed 1 year ago

Hi,

@rgalland and I, we independently simulated the living hell out of the schematics in DMG-CPU-Inside, hopefully catching all the bugs. These are our simulations:

We reported a lot of issues, but I think @furrtek is very busy de-capping some other chips, so we decided to remake the schematics in KiCad. :)

I removed the dash (-) between "CPU" and "B" in the other line, because the label on the chip always reads "DMG-CPU B", not "DMG-CPU-B". I thought since you take good care of spelling "Game Boy" the correct way, this should be corrected too.

We think our schematics are now mostly correct. There are still some swapped inputs of AND- and OR-gates, which are obviously not that important, we will fix over time.
