THIS!

Plus, you need to be a 68K ASM guru to code your own PickNMix. The current hack was done with the aid of the debugger under MAME! Not for the faint of heart. It's not worth the trouble, unless you want to make your own for yourself (like 1 of my customers did)

Do you know if this customer would be willing to share? It seems that customizing the game list would be much simpler that building the whole thing (presumably largely changing the titles + jump targets). Also personally I'll be very happy with this customer's list (I don't need it to be the perfect list)

I found 2 different PickNmix hacks for UNIBIOS online. You can look at how they work and see if it's something you're willing to do:

I would like to create a PICKnMIX version with your cart. Could it be easy for you to create a list with the ROMs used in the correct order that you add and the address where the ROMs start, and if there are extra ROMs like MS Turbo or new games added with the name? Something like this:
https://github.com/zardam/ub_vortex_multicart/blob/main/src/games.csv
 
I tried, there's not enough space left over in the 27C1024 to hold all the text. All the modifications I've seen did so by removing games from the list and calculating the new offsets using the MAME debugger. Removing games goes against the overall point of this cart (all-in-1). It worked for Razoola (he was removing hacks/duplicates) but those don't exist on this cart.

In any case, I sent you the list.
 
I am also interested in purchasing one of your multi MVS carts. I sent you a DM, thanks!
 
I received the cart a couple of weeks ago. I had a problem with my MVS boards, but leonk helped me and gave me support. Finally, all works great with the all-in-one.

Thank you!

I can't stress enough how much testing goes into every cart before they go out. Shipping international is expensive and frustrating if something goes wrong. MVS was not made for home use. They were commercial products that spent years powered on and many times, neglected. All failures I've seen in the past 2 years have been a result of the MVS board, and not the cart; even when original carts seem to work.

Thanks for the kind words and enjoy the cart!
 
I keep the first post updated with all known/current limitations. If the game is listed with an issue, it's still the case.
 
Received my cart today. Works great, super fast shipping and very friendly seller! Thanks man!
