ZarkonDrule: It's an awful release with a horrible smoothing filter on it sadly.
MysterD: Can the smoothing filter be turned off?
Or has anyone modded the filter out yet?
I don't know about modding, but I know the filter seems to be "baked in" (as in it seems they replaced all the textures with pre-filtered ones rather then just apply a filter during play), as there was a "bug" where a few sprites weren't filtered.
They have given no reason to think they will give an option for a non filtered version so far.
At the moment, sadly the best way to play the game is to play the original Saturn/PSX version on an emulator. Saturn version is the better one and is pretty cheap on ebay. It was never released outside Japan but there is a translation patch available :
