1. In CMakeList.txt comment out in if(AMIGA) : #  set(SDL1_VIDEO_MODE_BPP 8). Or intro will be of broken look. Need to report to SDL1 bug-threads ?

Add at top of : 

Source/diablo.h
SourceX/controls/devices/game_controller.h
SourceX/controls/devices/joystick.h
SourceX/storm/storm_dx.cpp


#include <cstdio>

(to avoid errors about non declared snprintf)

4. 

In the 3rdParty/Radon/Radon/source/key.cpp add at top:

#define _GLIBCXX_USE_C99_STDIO 1

(to make to_string() works)

5.  SourceX/dx.cpp have some bad for c++ stuff, on line 235, in the ifdef __amiga__ part : old_buffer = surface->pixels; that all for VAMPIRE, so
comment out all __AMIGA__ ifdefs (they to check if it 680800 / vamprire)
Also in SourceS/sdl_compat.h commeout out whole __AMIGA__ ifdef block.


6. SourceX/main.cpp:

#ifdef __amigaos4__
static const char* __attribute__((used)) stackcookie = "$STACK: 2000000";
#endif

----------------

SDL2 build:

1. do same changes in sources

2. hange in CMakeLists.txt in root in if(AMIGA) comment out set(USE_SDL1 ON) and  set(SDL1_VIDEO_MODE_BPP 8)

3.

And cmake configure will be like this now:


mkdir build
cd build

4. SourceX/storm/storm.cpp:

	#ifdef __amigaos4__
	snprintf(buffer, size, "%s", path);
	#else
