Great info @wickerwaka , thanks for sharing it! I checked known scanned schematics from games using this chip and pin 74 is not listed as input pin but as power pin, so it is involved for sure in DAC, as Vref or something. Also, some games list it as Vcc pin (such as Gunbuster, Double Axle) and...

Hey! The project is currently halted due to personal circumstances, but I hope to finish it soon. After confirming the prototype worked fine and as expected, I designed a new version of the PCB, with smaller size and easier to install, avoiding all those ribbon cables to take RGB signals, and...

Nice catch, Congrats! 👍🏼 I also love Bakraid. Btw, are you able to read eproms? The Bakraid PCB you purchased is the Unlimited HongKong version which is currently undumped and would be nice to be added to MAME 😄

Yeah, I didn’t realize that the kick harness connector isn’t the only thing to take into account, but also the size of the C board having it. A small redesign of the top piece, specially making that square a bit taller and wider, which is where the C boards is placed, would work. I dunno if...

I have this one for years, hoping some day reproductions would be cheap and in same quality (not 3D printed), to use in all my cps1 boards Mine has the small bottom part, intended to be used with small mobos, but a larger one also exists for bigger ones. Games with kick harness connector on...

Hi, price for: DUNGEON MAGIC ?

Last months I was working on a dump project . In this case the tool is intended to dump the internal ROM present on some MCU devices from the Toshiba TLCS-90 series. Some NMK games, such Thunder Dragon, Hacha Mecha Figher and Double Dealer, and some other Jaleco games, such as Big Striker, use...

Curious about “Nosferatu”. You mean “Nostradamus” instead?

curious about the differences in components between korean and japanese ones. Is it just a replacement of some components to proper ones in terms of brand, values.... or there are some unpopulated/different circuit in korean one? Btw, glws

I can assure this is completely true. I saved lot of money thanks to Joko's job. Much appreciated!

yep! that one is entirely based in the previous work of @Hatsune Mike. I only designed and made a small pcb (currently in prototype status) using the same FPGA he did, and adapted the HDL code to output CGA video signal using the same original DAC from Taito. :thumbsup:

Hi, I’m interested in two units of Reco PCB. Please, let me know when it will be available again. Thanks!

could you upload a picture of that Daioh proto pcb?
