Konami 054573 and 054574 reproductions

[Ace`]

I've made schematics and gerber files for the 054573 and 054574 video output customs used on the following konami boards.

Bucky 'o Hare
Cow Boys of Moo Mesa
Gaiapolis
Martial Champion
Monster Maulers
Mystic Warriors
Violent Storm
Xexex



Along with the gerbers the zip file also includes a list of all the parts you need (BOM) and some other pictures showing locations etc.
