Alien vs Predator, Captain America/Avengers and Mystic Warriors have in common?

[Javy3]

They are games that supposedly allow 3 or more players to play simultaneously but I have yet to find a rom that allows it.  I have downloaded a variety of Mystic Warriors and Captain America/Avengers and have only been able to play 2 players sim. at most.  Is there some step or BIOS I am missing or did they just not get translated to MAME?

make sure you are playing the 4 player rom (if that applies) and that the dipswitches are set to 4 player. Any issues with TMNT or Xmen?

That's what I mean.  I can't find a 3-4 player version of any of these games.  I have plenty of 3-4 player games that work and I found with no problem like X-men, TMNT, Knights of the Round, Snow Bros. 2, etc..  But for some reason there are a few games that supposedly are 3-4 player possible games but I just can't find the rom for them that allows it.  That's why I wondered if there just never got to mame or if something else is needed?

Looks like you need to toggle the dipswitch in MAME for 4 player mode. Bank 2 switch 6.

AVP is either a dip setting, or in game menu setting, I forget which exactly. This is one reason why I love LEDBlinky. When I was first setting up my 4 player machine, I'd scroll through the games and the controls would preview light up showing me which games were 3-4 players. If I started a 3 or 4 player game (as indicated by the controls), but it only allowed 2 players to start, usually the number of players could be changed in the dip settings or in game menu (Pretty Soldier Sailor Moon comes to mind too).

I was not aware you can do that..... How would I get to that menu/option?

[Fursphere]

In MAME - hit TAB while playing.  There will be a menu for the settings.

There is a dip switch setting in the tab mame menu?  Thanks I will try it.  So I would just select on for the multiple 1-4 players and is this a change I do to the specific roms or is it like the input change that can be general to all roms?

Wow, that is pretty darn cool that you could figure that out from LEDBlinky.

AFAIK you have to do that on a 1 by 1 basis.

Nice does it save.  And one quick question.  You said dip switch or in game menu?  I now know where to find the dip switch menu but what do you mean in game menu?

[Malenko]

you can hit F2 to go into service mode/menu if there isnt a dipswitch setting there might be a CMOS setting.

Thanks so much.  This weekend I was able to try it and I managed to get a lot more games to 3-4 player mode.  Thanks you so much, I learned so much more about MAME and can play some games I wanted to so badly with more players.

I have one last question.  It's a little off topic.  The frontend I use is Mala and I have Final Burn Alpha for 4 games (SFIII, Jojo's Adventure, MvC and SNK vs Capcom).  These games only show the rom zip shorthand name and not the full name like the mame files.  I tried to use Romlister to make a list for Mala but the list only shows up under mame and not for FBA.  I have no clue how to show/edit the full rom names on Mala?

[Malenko]

I use MAME for those games so Im no help, but glad you got the games working. I only mentioned CMOS and Dip because depending on hwo you have certain games set up, like NBA Jam, it can use one or the other.
