  • Another arcade PCB step by step repair. This time there's some graphical issues which are caused by a bad video ram as it turns out.

    Another great video ! I recently picked up a bootleg of this in Australia for $10 AUD. Still gotta take a good look at it. It currently has Dangerous Dungeons installed and what looks to be a homemade daughter card which I haven't seen before. It had a watch dog issue so I replaced the cap for it. It boots now but has some kind of graphical glitches. I have an eprom programmer / reader on the way so I should be able to verify the roms this week I hope. Keep up the great work 👍
    Thank you very much! If I can be of any help you can feel free to contact me!

    Hi, and thanks for your work. It really helps!
    I’m currently digging into the pcb repair, and i have 5 snow bros bootleg failing pcbs to experiment.
    Where can i find a logic probe like yours?
    Is there a site with the snow bros schematics?
    Can you share your jamma supergun schematics/pcb design?
    Keep the good work

    You can never have enough Double Dragon!
    For your Double Dragon knowledge and repairs alone, I shall dub thee Double Dragon Doktor.
    This information will be incredibly valuable for what I'll be working on as well. Thanks for the videos. =)
    PS: How are you recording your videos? It's nice and stable as you explain things and troubleshoot.

      I made this myself several years ago. It is a small pcb that serves as an adapter to neo geo controllers and a tv scart connector basically.
