    Konami Viper - LED Error Codes - Silent Scope Ex

    It’s working again 😻 but a bit complicated process. I desoldered the one-wire eprom and got the key with an Arduino script. Swapped the eprom to an other working pcb and generated a new NVRAM with MAME. Burn a new timekeeper and it plays again

    Sega Super Hang-On repair

    I ordered some 6116 ram.. have to wait for it.. but i'm confused that there is no activity at all on the address bus.. so in my opinion it doesn't look like a ram issue.. or can't be a ram issue the sound chip stop working at all?
