[Naomi/RA] Add the option the show the VMU screen + Add details regarding the order

[Immersion95]

At the moment, the option to show the VMU are hidden when a Naomi game is launched.

You could actually use VMU on some arcade boards with compatible Sega or Capcom VMU reader devices (MVC2, CVSPRO, SFZ3U, etc...)

It would be fantastic to see what was displayed on the VMU side.

Also, would it be possible to add information regarding what VMU to use for Naomi interoperability ?

Naomi reads VMU in B1 as the first memory card and VMU in C1 as second memory card.

On Naomi cabinets, maple port A is used by the Maple/JVS interface. So the first VMU is connected as first sub-device of port B (used for player 2 on a console), and the second VMU as first sub-device of port C (used for player 3 on a console).
The corresponding files are vmu_save_B1.bin and vmu_save_C1.bin.

I tested some arcade games with support for VMUs and apparently they don't use them to display dynamic information like console games do. Games simply display a static game logo. I'm not sure about vonot, ggram2 and gram2000.
Tested games: mvsc2 (static logo), cvs2mf, cvs2gd (static logo), sfz3ugd (static logo), vonot, f355 (static logo), ggram2, gram2000.

That's great !

Still, I would love to have access to those static image.

Regarding the information of the VMU, is it possible to have it in the VMU section ?
