I'm trying to play this game but i have no clue how it works. I'm using the REMOVED "fixed" version (it has some problems with korean characters in DOSBox) and it works but i have two main problems.

- Controls: I have no idea about the game controls and there is zero info on internet. NKB 0 and SUPR are the shoot buttons for 1P, but there must be at least a second button i cant find, for combos or something.
- Joystick: I cant get directions to work in this game, even choosing joystick in game and any joystick configuration in DOSBox, it just doesnt work, 1/2 buttons work fine tho. I could remap the KB into the gamepad but i want to use proper auto-firing support (without Auto-Hotkey stuff).

Has anyone tried it? Thank you.
