MVS Neo Geo Credit LED MAME support

[jtslade]

For those of us with converted MVS Neo Geo cabs it would be nice to have plugin support so that we can run a real MVS Credit LED thru mame.

I know that this might be involved but I think with a real MVS credit LED
there is a hardware driver onboard to run the 7 Segmented LCD built into the board.

What would be involved with processing the Neo Geo game board outputs when the player losses a life and the coin LCD takes (-1 coin) from the display.

Also to link the mame output of coin insertion to the MV-LED credit (+1 coin)

I know that most of this would be done in Mame but support for a LED Wiz or LED blinky to a standard LED

Maybe the front end can have a simple script to start the LED at zero, and any time the credit assigned key is pressed add +1

For the subtraction I am not sure how that would interface.

At the least it would appear that the MVS Neo Geo Mame cab was authentic.

[Visitor Q]

Does this work with all Mame games? Like I am not just saying in HS but Mame in general?

I believe another frontend ( Atomic?) had something similar where it remembered credits in between games but that feature was removed by request of the MAME devs because of the potential for abuse (i.e. putting it in public locations for profit).

Anything that has to do with credit maintenance will usually find strong objection from the MAME team.
