I'm trying my best to follow the instructions, but for some reason I cannot get "surfacepp" or "openglpp" to actually work.
In the PATCHES.txt notes I see:
+ Patch for pixel perfect scaling, created by Ant_222 (https://www.vogons.org/viewtopic.php?f=32&t=49160)
In the pixel perfect txt file i see
This patch adds three modes of software scaling
based on the 'surface' output type and one hardware
scaling mode based on the 'opengl' output type:
Each emulated pixel is represented as a sharp
rectangle with integral dimensions m x n such
that m:n approximates the desired pixel aspect
ratio (PAR), which depends on the emulated reso-
lution and the 'aspect' setting in the [render]
section. Whereas the standard PARs are them-
selves ratios of small integers, this mode will
yield the exact aspect ratio, provided the output
resolution is high enough for the game.
So, in dosbox.conf I set:
Run DOSBox, and the output console says:
"surfacepp" is not a valid value for variable: output.
I realize these are "patches", but is there something else I need to do to enable these features?
It should also be noted that the dosbox.conf comments were never updated, notice my available options:
# output: What video system to use for output.
# Possible values: surface, overlay, opengl, openglnb, ddraw.
