Correct way to fix vertical stretching

No need to replace the DOSBox version from the one included (SVN DAUM Jan 2015) by Steam.
How to: Just append the line "enable vga resize delay=true" to the 'dosbox' section of Hocus.conf file in 'Hocus Pocus' folder under the game folder. Done, the game is no more vertically stretched.

Other things you may be interested:-
1. SVN Daum DOSBox supports XBRZ scaling. To enable this, in 'sdl' section of Hocus.conf, change 'output = ' to 'surface' or 'overlay' then in 'render' section, change 'scaler =' to 'xbrz'.
2. SVN Daum DOSBox supports Direct3D pixel shaders. To enable this, in 'sdl' section of Hocus.conf, change 'output = ' to 'direct3d' then in the same section, append the line 'pixelshader=xxxxx.fx' (where xxxxx.fx is the name of shader file; the interesting ones are CRTxxxx which emulate the look of game in CRT monitors).
Note: the 2 above won't work together for they need different output.

@Vampire Woona It sort of upscales the game visuals and makes the game look better. However, it's experimental.

what do those other things actually do?
