I have been experimenting with 4P functionalities and here's what I know.
If I set these flags...Then I can read P1B and P2B inputs however they are just mirrors of P1 and P2 inputs...
//Force 4P HW Flags volMEMBYTE(0X10FEF8)=0x02; volMEMBYTE(0X10FEFA)=0xFF; volMEMBYTE(0X10FEFB)=0xFF;
That said does anyone believe it possible to write a function in the software that emulates the 4P Hardware?
In this case testing with mame would not be limited to mirror inputs for P1B and P2B (Player 3 and 4)?
On the trivia side of things I attempted to get Kizuna Encounter running with 4 controllers on Mame to no avail.
Does anyone know if Mame is capable of processing 4 separate inputs for Kizuna?
On the trivia side I can confirm that it is indeed possible to play Kizuna with 4 separate inputs via mame!
I was able to verify this with Mame 0.238, Kizuna and NeoGeo Bios set.
The trick is to load the clone kizuna4p! Easily accomplished if you use the mame UI to launch your rom.
Upon pressing TAB once the game is loaded you will see the game has 4 mappable inputs!
Update - Blastar - summitted a tip if you are playing kizuna 4p you can rename the uni-bios to match one of the supported bios names then you will gain access to all the uni-bios functionality!
