    Hmm.... That might be a reason why I lost suddenly address-line... Need to resolder couple of pins and see if it helps.

    Sega System 16B multi kit installation & support

    Ok, last week I finally found my NOS 8MHz Z80 CPU and installed it -> instantly got good sounds also with Golden Axe etc. Seems that now the sounds do work just fine. But... then I noted today another issue - several games (which booted earlier just fine) wont boot at all. I mostly get black...

    ST-V multicart game selector with LCD screen

    Need to upload the code (not online at the moment), but there is a program already loaded to arduino. It should just boot when powered up. VERY important: if you want to reprogram the arduino, remove it from the selector and program it separately, then put back to the selector sockets. Note the...

    ST-V multicart game selector with LCD screen

    All previous interest PMs replied. And I have more selectors available now. At the moment though only with yellow/black display, not the blue/white as usual. I have ordered more blue/white displays, but they haven't arrived yet.

    Sega System 16B multi kit installation & support

    Some late night tests with cold spray: I got the issue spotted around pins 21-27 on Z80. It's a little bit odd that only few games do suffer from sound issues considering which pins are these. Anyway, I have a NOS Z80B in some box, will dig that up and try changing the Z80 CPU.

    ST-V multicart game selector with LCD screen

    I let you know when ready. I just got a note that last package arrived (PCBs) for picking up. I can start putting selectors together weekend/next week. First I'll get the pre-ordered selectors ready though. But there will be some extras after I get them sent out.

    Sega System 16B multi kit installation & support

    Results from last night (sound problems, mainly with Golden Axe anymore): Removing solder and resoldering U14 + GAL sockets did no change. I decided to try pushing chips down and booting the PCB at same time. Sometimes Golden Axe got sounds and they kept playing when I removed my fingers. Only...

    Sega System 16B multi kit installation & support

    Last night testing: All games had sounds, except Golden Axe (and Shinobi during first try). Also I noted that Dynamite Dux seems to hang up in various places after playing a while. Shinobi - I can get sounds vanishing when I push or pull U14 or GAL (usually U14), also I can get sounds back with...
