Take a look. Also included in the thread is 2 little switcher options as well.

Vs Goonies/Vs Gradius Combination Daughtercard

This brand new product allows you to load both games at the same time on a single side of a Nintendo Vs board!  Just flip a switch and press a button and you can switch to play either Vs Goonies or Vs Gradius.

This daughtercard is fully assembled, tested and working prior to shipping.  All you have to do is install your existing CPU and PPU into the sockets and then install this onto your main Vs PCB.  The pins used on this card are very similar to the ones used in original daughterboards.  We opted to use these because they are much more robust than round machine pins and hold up much better when installed and removed from sockets over time.

Once installed on your main board, allow 30 seconds for the game to boot when the daughtercard is installed.  To change games, simply flip the toggle switch and then hold the reset button for 2 seconds.  The game will reset and the other game will boot.  Super simple!

Each daughtercard is $115 shipped within the US.  International shipping  is additional.  We also have a limited supply of Nintendo CPUs (RP2A03) available at the moment for an additional $22 (when purchased with a daughtercard) and will arrive pre-installed on the daughtercard.  We do not have a source for PPU’s so you will have to supply that item.  Simply tell us which Vs PPU you plan to install and your card will be custom configured based on your selection.

All combination daughtercards will come with a remote-wired toggle switch and push button switch that are easily plugged into the board.  However, if you would like a daughtercard configured to only play one game (instead of the combination), we can fulfill those custom requests as well.

First is the all new VS Top Gun Castlevania Switcher

 


The switcher currently only works on a Top Gun Daughtercard with a Top Gun RC2C05-04 PPU and allows you to switch between Castlevania and Top gun.
Simple design allows you to remove a single eprom and install this in its place.
You must have a Top Gun Daughtercard and a main VS PCB, this is an add on card for them.
The picture below show how it is installed. Again no main pcb or Top Gun daughtercard is included.
$50 shipped in the US. International shipping is additional.





Next is the Goonies Gradius Switcher. This has been around for a few years now.
It takes the place of the two EPROMS on your existing Vs. Goonies or Vs. Gradius daughtercard and will now allow you to play both games on the same board. There is a simple push button switch that will allow you to switch between games**. You will no longer need two separate daughercards to play these two great Vs. titles!!!Also $50 shipped in the US. International additional.​




Nintendo Vs. Chipsets:

$20 plus shipping for daughtercard EPROMs
$26 plus shipping for 6 EPROM sets
$45 plus shipping for 12 EPROM dual game sets
I can supply complete lineup of known Vs. game chipsets.
Identical copies of original ROMs, all tested on original hardware before shipping.

Please stay tuned to this page for more great updates

besides this item from retrousb: http://www.retrousb.com/product_info.php?cPath=30&products_id=87 that has been unavailable for years now, no not that I am aware of

The early ones with the Japanese writing on the CPO had the service door. The early ones also had other differences as well.

Later ones removed them and changed, not sure why? Maybe people breaking into them? Maybe just a design change.

Tetris also works on the 0001 PPU.

Dr mario requires a daughter card specific to the game to function.

Not a new source for them no. Just have to look for them on ebay and in forums.
What PPU in particular are you looking for?
Might want to try a wanted to buy post as well.

I have never known anyone to get a blue or pink gun to work in a Nintendo cab. They may look similar but the optics are know where near close to eachother.

I have known a few people that took the zapper optics out and shaved down the pcb to fit inside the gun and then it will work.

People have been mistaking the pink and blue for Nintendo guns for over a decade, and they are often listed as Nintendo guns then.

Some new games have been added to the site. Check the site for cart compatibility.

New product for VS Goonies and VS Gradius owners:
http://www.pc-10.com/newproducts.html
Here is a review This Old Arcade did of my VS Goonies and Gradius Game Switcher.
https://youtu.be/YHLFyyeVTKE

Playchoice guns will work in a vs, vs guns will not work in a playchoice.
A playchoice gun will have 1 connector with a wire loop in it and only have 4 wires total going to the 2 connectors. A vs gun will have 6 wires going to the 2 connectors and no wire loop. Nintendo guns are orange or black, can be either plastic or rubber.
Nintendo guns arent blue or pink.

Very neat thing I learned today about VS Star Luster. It can go on 5 different PPU's based on dipswitch settings on the main pcb. Before this I always thought it just went on the RC2C03B (Duck Hunt) PPU.
As it is listed on Johnsarcade. But it can go on the following PPUs and here are the dipswitch settings:
RP2C04-0001
DIP 6 ON DIP 7 OFF DIP 8 OFF
RP2C04-0002
DIP 6 ON DIP 7 ON DIP 8 OFF
RP2C04-0003
DIP 6 ON DIP 7 OFF DIP 8 ON
RP2C04-0004
DIP 6 ON DIP 7 ON DIP 8 ON
RC2C03B/RP2C03B/RC2C03C
DIP 6 OFF DIP 7 ON DIP 8 ON
If anyone is interested for a limited time I will offer the 6 eprom chipsets for $20 plus shipping to get more of these out into peoples hands to play.

For ease of use and availability, I have decided to combine all my products and services, including future projects into one thread in this section.
