Will answer all of your questions :)

1. GBA bios can you find on google. it’s about 13kb
Unzip and rename it to gba_bios.bin
Place it in /opt/retropie/emulators/gpsp/raspberrypi/

Should start now after a reboot

2. To remove IBM, Apple and ports(pc?) just go to
/home/pi/retropie/roms

Open Apple, ports and others folder and remove the start file inside

Reboot the Raspberry pi and they should be gone

3. I wish i had an answer for N64, but i can’t get it to work either. I have been trying everything and i find it hard to get answer how to get it to work. I know that it has major fps problems but it would be fun to get it going :)

To make 1 and 2 easier download WinSCP
login in with
username: root
pass: ????

To make a password for the root enter emulation station and press F4
type this in the commands

sudo passwd root

Type in your password twice. When you type will there be no letters. just hit enter when you are done.

Hope this helps

[quote=83558]i actually got gba to work although the controller mapping was a little weird I must say. I was able to play some games in there but most weren’t playable because of the controller. It seems Y is start for most of them. Thank though. I really hope they will put out a new version of retropie with this and n64 working out of the box soon. Thanks again! [/quote]

For nes, snes, sega etc is’t F1 to map your keys for Gba is’t… I don’t know :D

But on my Xbox360 controller is’t Y + R2…. :)

hey kugwa:
i believe with cyberduck (or any other SFTP client) you simply have to right click on the file itself, and select MOVE or something similar to that. type in the directory explicitly: /opt/retropie/emulators/gpsp/raspberrypi/

or connect over SSH and move it from there
