Configuration options:
--------------------------------------------------------------------------------
-- Dingoo Clock --
No overclocking actually!.

-- Video Depth --
Sets MAME´s internal video depth (NOT the Dingoo´s video depth).
8-bit is generally faster though some games require 16-bit.
Some games may be faster in 16-bit mode - it´s dependant on the game driver!
Auto: The emulator uses the most suitable video depth.
8 bit: MAME uses 8 bit color (DEFAULT).
16 bit: MAME uses 16 bit color.

-- Video Scale/Aspect --
The video aspect is configured with the following combination of options:

Normal:
Nominal video resolution (320x240). Games with a resolution less than this
have a black border. Games with a resolution higher are cropped.

Scale Half Size:
Useful for high resolution games like Rampage and Tapper, etc. 8-bit video
mode is quickest as extra pixels are just truncated. 16-bit mode does pixel
mixing resulting in a nicer, but slightly slower display. Should still be
quick enough for most games.

Scale Horizontal:
Useful for games like R-Type and Final Fight, etc. Other smaller resolution
games will stretch out to fill the screen. Take from MAME4ALL Wiz version
(code originally from Notaz & Franxis).

Scale Best:
This is a generic rescale that can resize any screen to fit the Dingoo´s native
320x240 resolution. It produces the best quality scaled display as pixels are
merged both horizontally and vertically. The downside is that it may be slow.

Scale Fast:
his is a generic rescale that can resize any screen to fit the Dingoo´s native 320x240
resolution. It produces a good scaled display as pixels are merged horizontally.
Speed should be somewhat quicker than "Scale Best".

Rotate:
The display is rotated from landscape to portrait orientation. All the above scale
options are present for screen rotation.

-- Video Sync --
Normal: Single buffer and dirty buffer is used (DEFAULT).
VSync: VSync activated (Unlikely to be ever implemented due to lack of hardware support).
DblBuf: Double buffer
