Hey. Not to hijack the post, but i saw someone had trouble installing chromium on the pocketCHIP. I have done this a bunch of times, and it't not that hard at all.
Here is what i do.
sudo apt update
sudo apt install xdg-utils
wget https://dl.dropboxusercontent.com/u/87113035/chromium-browser-l10n_48.0.2564.82-0ubuntu0.15.04.1.1193_all.deb
wget https://dl.dropboxusercontent.com/u/87113035/chromium-browser_48.0.2564.82-0ubuntu0.15.04.1.1193_armhf.deb
wget https://dl.dropboxusercontent.com/u/87113035/chromium-codecs-ffmpeg-extra_48.0.2564.82-0ubuntu0.15.04.1.1193_armhf.deb
sudo dpkg -i chromium-codecs-ffmpeg-extra_48.0.2564.82-0ubuntu0.15.04.1.1193_armhf.deb
sudo dpkg -i chromium-browser-l10n_48.0.2564.82-0ubuntu0.15.04.1.1193_all.deb chromium-browser_48.0.2564.82-0ubuntu0.15.04.1.1193_armhf.deb
That's it. I hope it can help someone trying this game, that looks really good btw.
