GBA Emulator Help

Hello, im new to running Emulators on RetroPi

only one i have installed is a GBA emulator, i installed the Bio and a few Roms enter a game a quickly discover on the D-pad works and the start button functions as a jump. is there a way i can do a remap on my button layout and also is there any hotkeys for me to exit the game?

I recommend you remove the bios and use mGBA, I hope you find this usefull

Gavsterr

i will give it a shot, not sure how to run it on the Retropi i see how to get it going on PC though lol. ill have to read into how it works

@gavsterr I don't use a bios with GBA and I haven't had any issues other than swapping around the emulators whemever I have a compatibility issue (I have only had one GBA compatibility issue and that was with DK King of Swing. But as soon as I swapped the emulator, it was all good).

sergioad

Indeed, the only reason to use a bios in my opinion is for that gorgeous GBA intro but is better to not use a BIOS

Gavsterr

Okay Great! maybe a silly question, mGBA is a file i need to download and transfer into retropi? or is it a emulator pre installed? i am still a scrub...

sergioad

@gavsterr preinstalled and by default

@gavsterr you'll have the answers you need in the docs.

Controller Configuration
You can change the default emulator for gba using runcommand launch menu.

Also, look at that message on top of every page of this forum:

@meleu
i apologize, i didnt quite see what i was looking for in the Forum. ill make sure to look closer

as to everyone else Thanks for the Time/Tips/Advice!

Gavsterr

just in case anyone was curious. the issue wasnt the controller config or the emulator/settings
it was the bluetooth controller. the N30 by 8bitdo for whatever reason would not follow the same button mapping, switched toa PS4 controller and everything worked perfectly

meleu

@gavsterr did you enable "save configuration on exit" in RetroArch?

Gavsterr

@meleu sorry for the late reply i have, the issue seems to be only with my blue tooth controllers, usb works just fine. on all bluetooth controllers all the buttons are remapped into odd locations or not at all, for instance the "Start" button was the "A" button and the d-pad worked normal, none of the other buttons had an response.

meleu

@gavsterr do your bluetooth work on EmulationStation and don't work in games?

What models are you using?

Gavsterr

@meleu yes the Controller works fine in the station menu but when in-game it no longer works with the configuration i had set up. Its the F30 by 8bitdo.

meleu

@gavsterr did you install them following the steps in the docs?

https://retropie.org.uk/docs/8Bitdo-Controller/

The problem you're describing is typically related with the "8bitdo hack". Check the step 4 in the doc.

@meleu the "Hack on" was the issue, but i noticed it didnt well with it off. the problem i found was that the Firmware update didnt go through on the controller, once i was finally able to get it updated and reset it up following the step by step guide you linked i was able to get it working perfectly and connecting every time. Thanks for your help in my small matter.
