Reply To: Where to put gba bios file in retropie

[paulybo]

chito, I had the same issues running 2.4.2 but I was able to find the root directory of gpsp going one directory at a time. Here are my detailed instructions. The “quotes” should not be included in the code, but otherwise that is the text I entered.

The new file directory is here: opt/retropie/emulators/gpsp/

how to get gba games to work on retropie (using 2.4.2)

press f4 to exit emulation station

type “cd /” to go to top root folder
“cd opt”, you can see the files/folders in each directory by typing “ls”, if desired.
“cd retropie”
“cd emulators”
“cd gpsp”
this is the root folder of gpsp in 2.4.2 (opt/retropie/emulators/gpsp/). If you type “ls”, you can see the program gpsp is in this folder. The error message said to save gba_bios.bin here.
To download gba_bios.bin, first download the zip file by typing
“wget http://www.roms4droid.com/files/bios/gba_bios.zip”
to unzip type
“unzip gba_bios”
This unzips your file and you now have gba_bios.bin saved in the same folder as the emulator gpsp.
Type “emulationstation” to start emulation station and choose GBA (assuming you have already transferred over your roms)

I want to emphasize the steps below will work on any version of retropie:
To download gba_bios.bin, change directory until you are in the same directory as the program gpsp (opt/retropie/emulators/gpsp/ for 2.4.2, /opt/retropie/emulators/gpsp/raspberrypi/ for 2.0 to 2.3, home/pi/RetroPie/emulators/gpsp/raspberrypi/ for earlier versions.)

Download the zip file by typing
“wget http://www.roms4droid.com/files/bios/gba_bios.zip”
to unzip type
“unzip gba_bios”
This unzips your file and you now have gba_bios.bin saved in the same folder as the emulator gpsp.
