Dreamcast Controls Issues

[JoargTheBard]

For the past couple days, i have been trying to figure out how to setup the controls for Dreamcast. I have 4 controllers hooked up to my pi2 running 3.7, 2 8Bitdo NES30 Pro's, and a Raphnet 2nes adapter. The emu picks up the raphnet controllers just fine, but since there arent enough buttons to play much of anything besides Mr. Driller, i would like to get the NES30 pro's working. i have tried editing the emu.cfg in both locations (/home/pi/.reicast/emu.cfg, and /opt/retropie/configs/all/dreamcast/emu.cfg)to reflect the correct joypad id's and mapping files but everytime i start up reicast, it reverts back to the old configuration. i feel that if i were just able to figure out why it keeps overwriting, i would be able o get it to work, but i cant for the life of me get it to recognize the new control settings.
Im down to the last couple of things i would like to get setup before i can call my NesPi build done, so this hang up is incredibly aggravating.

Any help is much appreciated!

Hello,

When you start reicast, you launch a script :
/opt/retropie/emulators/reicast/bin/reicast.sh

In this script, you got a function : mapInput(). It's editing emu.cfg
I think you can comment a line to disable mapInput() (near the end of file):
getAutoConf reicast_input || mapInput
just add "#" like this :
# getAutoConf reicast_input || mapInput

Or change this line (begining of the file):
local conf="$configdir/dreamcast/emu.cfg"
to
local conf="$configdir/dreamcast/emu.cfg.autoConf"

I think it will work :)

SUCCESS!!! Thank you so much! i never would have found that on my own! i am having one other issue though. it works fine if i just have the four controllers in the mix, but if i plug a keyboard in, it too takes presidence over the bluetooth controllers in the index list and bumps them down to js3 and js4 instead of js2 and js3 like i have in the .cfg file, even though i dont have the keyboard setup for controls. i was wondering if there is any way in the core config files of the pi to force a controller to take a certain index when connected. it would solve a lot of the issues im having with some of the other emu's and ports as well. again any help is much appreciated
