So to summarize what we can do here:
_ can post PIC codes. It will be usefull to repair our broken arcade games.
_ can post tools (frontends, HDD decription tools or methods...). Usefull, too.
_ no ROM authorized, of any age (even old).
_ already converted / hacked systems can be sold, even with a non legit game installed
So let's share PIC codes !
As I said before, I asked Sega Aracade Europe for repairing my games (olds PCB System & Model series, Naomi, Chihiro, Lindbergh) and they don't do it anymore. I asked to buy new replacement games and parts, they have nothing to sell me anymore. They can sell used cabinet parts if they have because on top of selling new cabinets, they sell used cabinets, but's it's not the same thing (and actually this firm is not realy "Sega", just a licence to use the name). Actually, I asked very recently to repair one of my RingEdge, and the answer was that's not possible anymore, too. So these systems are not supported anymore by Sega.
So if we want want to repair our games, that we legally bought, we have to share knowledge, cause Sega won't help us. I have got hundreds of arcade games, all genuine. And as I said before, I can't find any Lindbergh or older game still in use in arcade center here. I don't want to bootleg or hack, just to repair my cabinets!
@Darksoft if you fear hosting some files, I can do it. Not another website cause I like this one, just hosting files.
