Nunuhara Cabbage 81455baeb4 Implement more DrawGraph/SACT2 functions 
5 functions:

    SACT2.SP_SetDrawMethod
    DrawGraph.CopyStretch
    DrawGraph.CopyStretchAmap
    DrawGraph.CopyReduce
    DrawGraph.CopyReduceAmap

SP_SetDrawMethod is not pixel-perfect to System40.exe, but its pretty
close.

I'm not sure what the difference between the Stretch/Reduce functions is
supposed to be. They seem to do the same thing.

Also, the ugly macros in sdl_draw.c are replaced by higher-order
functions.

With this commit, Sengoku Rance runs up to the menu without exiting due
to unimplemented HLL functions.

xsystem4

xsystem4 is an implementation of AliceSoft's System 4 game engine for unix-like operating systems.

NOTE: This is a work in progress. Very little is implemented so far.

Building

xsystem4 uses the meson build system.

mkdir build
meson build
ninja -C build

Running

You will need to create an AIN file using the System 4 SDK compiler. Then simply pass it to the system4 executable.
