retroarch.cfg for Mame ?

mulder79

i have tried using the TAB option within MAME but again certain keystrokes do not return any signal.. its very strange as all the keys which are mapped within the ALL folder work in SNES and MEGADRIVE etc but not in MAME

Also tried too see what happens when I plugged in a USB Keyboard and certain keys respond but not others.

Can someone explain ?

Thanks

@mulder79 what keys? retroarch abstracts the keyboard. certain keys might not be available, but if you give me any information I can test.

also, what mame-libretro core? there are many.

I have checked through this forum for keys that will be problems an believe I have avoided using them.

How shall I attach my retroarch.cfg file ? shall I just paste it in here ? its a long file

I am using the mame-libretro emulator, 2003

That's my retroarch.cfg file link below

For example If I press the player 4 A button (which is keyboard letter b) I get no response back within the mame emulator but do within a snes game.

anyone else have any ideas for this is not working ?

its mega frustrating :(

@mulder79 i think i see the problem. that cfg file has multiple things defined for each player. eg
input_player2_a = "a"
input_player2_a = "nul"

you probably want to get rid of the second ones :)

just FYI when you add in new rows you should double check they don't already exist (i think they pretty much always will)

is it safe to say that I can delete all the duplicate entries for players 1 - 4 ?

@mulder79 said in retroarch.cfg for Mame ?:

i think so - all the ones with "nul" you should be safe to delete. if there's two for the same player + key that are not null, you'll want to check which one is the right one.

mulder79

its weird how the duplicates have no negative affect on SNES, Megadrive, NES etc but when it comes to Mame its as if it reads the last instruction ie the 2nd entry, in my case the "nul" entry

mulder79

I removed all the duplicates and still this does not work.

The odd thing is that I seem to have a retroarch.cfg file appear in the libretro-Mame folder which does not look like my setup, its like a bunch of random keys. I will paste this in this evening when I am back at home.
