Now it actually says something about what exactly it tries to open, also on "cancel" it exits gracefully.
Proposal: instead of checking one thousand return codes, which are easily ignored, I suggest using an exceptions (this part of emulator doesn't require execution speed, so exceptions here would be just fine).
A new function was introduced to abstract the setup of input devices for each os: os_SetupInput().
I hope I implemented this everywhere correctly and the behaviour is identical to before.
The new function mcfg_CreateNAOMIJamma() creates the NAOMI Jamma interface and is hidden behind a compile flag (same as before).
The previous function mcfg_CreateDevices() was renamed to mcfg_CreateDevicesFromConfig() because it creates the devices based on the configuration (``nb`` setting).
This adds support for separate config and data dirs.
On Linux, these will be compliant XDG Basedir Specification, i.e.
XDG_CONFIG_HOME and XDG_CONFIG_DIRS (or XDG_DATA_HOME and XDG_DATA_DIRS
respectively). On all other platforms, there currently just set to the
homedir path (so no previous behaviour has been changed).
If reicast wants to read and write a data file, it just calls
get_data_path("/samplefile.txt"). If it does not need to write to
that file, it just uses get_data_path("/samplefile.txt", false). That
way, we can also use system-wide dirs (like /usr/share/reicast on
linux), that the user usually doesn't have write access to.
The same applies for config file, where you use get_config_path(args)
respectively.
This required moving the SH4_TCB outside the exe, as new tables that belong on the executable are ignored.
This isn't perfect, but there's a large area to scan for available address space so it shouldn't be a problem
This commit adds the DirectSound audio backend, which is a modified
version of core/oslib/ds_audiostream.cpp.
Porting this was a bit tricky, since ds_audiostream.cpp defined 3
extern functions that the other backends didn't have:
* bool os_IsAudioBuffered();
* bool os_IsAudioBufferedLots();
* int os_getusedSamples();
I came to the conclusion that these methods are obsolete since they are
only used core/windows/winmain.cpp in the function void os_wait_cycl(u32
cycl) - which is used nowhere. Thus, I removed os_wait_cycl and the
headers of the three functions in core/oslib/oslib.h. I also removed the
functions themselves (except for int os_getusedSamples(), which is still
used inside the directsound backend, but can safely declared static for
that purpose).
The DirectSound backend will be included during compilation if HOST_OS
is OS_WINDOWS.
Notes:
Disc swapping should work on .gdi files (probably .chd files too).
Swapping with .cdi files is not currently supported because we currently create inaccurate TOC for them.
Only x86/Windows has a disc swap handler right now (ie: you can't swap on Android).
