ODROID-C2로 오락실 게임기 만들기

여기서 recalbox OS를 다운 받는다.

https://archive.recalbox.com/

8GB Sd Card를 준비한다. OS와 ROM 파일을 큰 SD 카드에 같이 저장해도 되고 USB 이동 저장 장치에 게임 ROM만 따로 저장해도 된다.

etcher를 설치하고 다운 받은 recalbox.img.xz을 선택한다.
https://etcher.io/

게임 롬을 담을 USB stick을 준비
전체를 FAT32나 NTFS로 format한다.

ODROID-C2에 SD 카드를 연결하고 전원을 넣으면 recalbox 화면이 나온다.

XBox 조이스틱과 USB stick을 연결한다.

키는 다음과 같다.
A -> enter(OK)
B -> back
start -> setting menu

"MAIN MENU" 진입한다.

아래와 같이 "STORAGE DEVICE"에 앞에서 format한 USB Stick을 선택한다.

그리고 USB stick을 PC에 연결하면 recalbox란 폴더가 생성되어 있다.

여기서 중요한건 bios 폴더와 roms란 폴더이다.

bios란 폴더에 neogeo.zip을 넣고

roms/neogeo/ 폴더에 neogeo 게임 롬을 넣으면 된다.
