Hi Guys, i have a MV1B that is watchdogging in the NeoDiagnostic, the test stops at "checking RAM/OE" and keeps resetting (board with original bios is in watchdog state). I was wondering if anyone has ever shared a schematic to check continuity on cpu, ram and bios. I know you can find MV1A but...

I fixed it some months later my post, it was a bad 256ram near the socked bios. Also, some ls245 smd buffers between cart & sram

May i have a chance to have CHINA GATE here with me? I've been searching this game for a while... but i'm not in the USA...

Well, all the last 15yrs arcade hardware is based on a pc. Multi's are great for many reasons, you still keep the original harware where they were supposed to be played first. If you have the arcade cabinets, some are essentials to have (for example a Lindbergh multi if you have a shooter...

Awesome stuff guys. I wonder if @twistedsymphony tryed an everdrive? Mine didn't work and i don't have any else.

Love it :) Thank you guys, specially @twistedsymphony that exchanged this for my repro pcb gerbers. No more destroying originals carts, on both systems :D Now i'm curious to know about everdrive compatibility, will it do? 8o

You need to have all the "os" files in the HDD, they are in part 5 of the Mega Link : https://mega.nz/folder/zMhRDQ5T#BwWjX4sXMjfeDe4R26_eGA The file extension (001,002,etc etc) gave me a ZIP as one file, then i extracted it and put in the HDD with the others (also 001,002 etc). I don't know if...

Awesome, thank you. Looking forward to have one then :)
