라즈베리 2B + waveshare 35a + MAME 0.182

귀찮으니 img 받아서 그냥 까세요 수준으로 대격변 ㄷㄷ

귀찮아서.. 스크립트 분석하면 될걸.. 썡으로 뒤지는중

일단 화면 갱신이 꽤나 느린데

/etc $ grep -rni "fbcp" ./ ./rc.local:21:fbcp &

[링크 : https://github.com/tasanakorn/rpi-fbcp]

동영상을 보면 확실히 fbcp를 통해 복사하는거라 그런지 화면 갱신이 느리다. (cpu는 5% 미만이긴 하지만)

그래서 아래처럼 설정하고 다시 찰칵

기분인진 몰라도 확실히 좀 빨라진 기분?

일단 mame를 깔고

gnome 어쩌구 말고

mame를 실행하니 CPU는 미쳐 날뛰고(라즈베리 2B인데 오버 해야하나..)

/dev/fb1 덤프해서 보니 RGB565 480x320으로 복원

+

HDMI로 해도 느린건 마찬가지(아니 해상도 높아져서 더 느려진 기분.. 실행이 안되고 뻗는 수준?)

0.78 구버전을 구해서 빌드 해보려니 소스를 못 받는다.. 아놔
