Problem with 2 player 8bitdo on mame 2010

[Chrysro]

Hi, I am new in this forum, the english is not my native language, then sorry for every mistake I could do .

I love Retrox, but I detect a very annoying problem when I tried to play Street Figther II alpha and many other figthing games on MAME 2010,something is wrong with the second gamepad (FC30 PRO) , the b button and R1 doesn't work, when in the first gamepad does (NES30 PRO). I tested it in all the other emulators and the problem is only in MAME , I tested it too in the controller tool, the gamepad is working well, I assume thet the problem is the emulator config for the second player.

Please HELP ME, and THANKS for this wonderful app.

Can you try the same game with Final Burn Alpha?

the problem is not with the game, it happens with many more, with all the games wich requires 6 buttons, for any reason the second player is limited to 4 buttons, many of my roms wont work on fba, i can try but is not a real solution for the problem. I read a time ago that in old version of retroarch the second player is limited to 4 bittons and the 3rd and 4th to 3 bittons, it migth be related.

Do you have a link for that info about RetroArch?

The code seems right in the RetroArch side, but the machine for several of those kind of games (CPS2) have a special treatment for buttons 4 and 5. Although, the MAME code hasn't updated that part.

Also, there are 4 MAME versions that you can choose in the game details screen, have you tried a different one? if not, can you?

I found a kind of solution changing to mame 2014, and seems work, I think the problem is with older MAME versions only , I must check if mame 2014 can handle all of them.. Thanks !

You need to pair the 2nd controller as a keyboard by pressing down one of the buttons when turning on then map it thru the mame config menu

not more, 8bitdo did an update and no more keyboard mode. the problem is solved changing to mame 2014 or fba . but its generates another problem, it's imposible to press two buttons simultaneously, no special moves in some games, in newers version of retroarch the issue its fixed. I have to wait for an update for the multiemulator retrox, and it will we nice if we can choose between the 2 fba cores available. ( some games runs better en fba2012). Catrin, is it coming soon an update of the multiemulator based in a newer version of ra?

Update released

[Chrysro]

oh so sweet!, changelog ? I can't see still the update, how can I do it?

The next time when you open RetroX and try to play a game that uses the updated emulator, it will autodownload the new version. It should have happened already
