It works, try playing BBPSX as Non-steam game on steam, set up your controller configs, enter Big Screen Mode (I'm not sure, i think it just work without Big Screen Mode). Voila, you can use native PS1 buttons.
episodic releases would be great
Well polished, BEST crafting/alchemy system, Fast paced custom battle system, and beautiful game map.
though many very small graphical fails but still good in term of gameplay..
