A new project i'm working on for the arcade fans here.
Konami Gyruss, possibly the best shoot em up ever. Boards are 'riddled' with custom ics that go bad and are black boxes. I bought a bootleg board last year that had a custom daughter board, which matched the original layout and replaced of alot of the customs on the pcb.
So, i decided to make a reproduction of this, not an easy undertaking, but i wanted to have a backup for my own board, fix a board with all the customs missing, plus be able to help keep other boards going long after the customs fail. There are some single replacements out there for a few customs, but this doesn't help if you have a board with 1 giant customs replacement on it, whereas a new giant customs replacement can help everyone!!
So i took the plunge and recreated it
Now the fun part came for testing there board and whether it would work. Alas not, and i had varying screens of garbage and messed up pictures.
However, after alot of head scratching and logically going though the design, lots of swearing, lots of hours and tea i found the issues
Now a fully working board. And the image quality seems alot better than before, better contrast, better sharpness, better colour balance etc All together better
Now to get some rev2 boards made and see if people want some for backups, spares, replacements etc
