I couldn't manage to get it working normally, it only shows half of the screen.
I heard of a solution that is resizing the chankast window size before running the image, but it didn't work so lets see if you guys can give me the solution
It didn't work with alpha 25 so i used chankast_old_gfx and resized to around 16:9 as it told me on some website and it worked.
Unfortunately the game was dubbed in some weird language and it was too much of a hassle to set up the keys in the old chankast mode so i just threw the game away.
