Fix Tandy low notes in Zak McKracken and Maniac
Mansion Enhanced

Comments from NewRisingSun:

The low notes in Zak McKracken's intro still sound wrong in
all emulators when compared to a recording of its output on
a real Tandy machine.

The reason is that the game writes a
period of zero, which does not mean zero, but 1024, similar
to the 8254 PIT's period of zero meaning 65536. Current
tandy_sound.cpp tries to account for that but does it
incorrectly. Attached patch does it correctly, fixing Zak
McKracken's intro, as well as one flubbled note in Maniac
Mansion Enhanced.

Fix ARM dynrec dynamic core FPU by only passing stack pointer

Update dynrec core for ARMv8 systems to generate shift
instruction. This fixes dynamic core (dynrec) on ARMv8 systems
including ARM-based M1 Macbooks.

Fix a serious bug in dynrec dynamic core where calls to handle
x86 FPU instructions erronously passed the entire FPU status
word instead of passing only the FPU stack pointer. The result
of this error was that floating point was erratic, buggy, and
often caused memory corruption in DOSBox-X eventually leading
to a crash. It should now be possible to properly run DOS games
on dynrec based systems, including ARM-based M1 Macbooks, that
use the FPU. (joncampbell123)

Includes tentative ARM fixes by adding (yet untested) generator
code for the ARMv4 risc backend.

Notes from Ringding - (ported to 4467)

2021-10-21, 13:56 Fairly mechanical update of the mentioned patch to current
SVN. Only build-tested (on Linux). Specifically I did not check if additional
machine state items w ere added that would also require saving and restoring.

EDIT: Also pushed here because all this shuffling of huge subversion diffs is
really annoying:

I created patch file for sn 4176, hope correctly

In hardware.cpp I faced issue with variable std::string capturedir; Newly it
was defined as static which makes compilation errors in save_state.cpp :

save_state.o: In function `SaveState::save(unsigned int)':
save_state.cpp:(.text+0x7b4): undefined reference to `capturedir[abi:cxx11]'
save_state.cpp:(.text+0x7de): undefined reference to `capturedir[abi:cxx11]'
save_state.o: In function `SaveState::load(unsigned int) const':
save_state.cpp:(.text+0x165a): undefined reference to `capturedir[abi:cxx11]'
save_state.cpp:(.text+0x1684): undefined reference to `capturedir[abi:cxx11]'
collect2: error: ld returned 1 exit status

changing it back to non static solved the error, how it should be fixed
correctly ?

Notes from SedrynTyros - (ported to 4074)

2018-10-19, 07:46
Oh yeah, definitely still interested in having a save states patch compatible
with current DOSBox builds! I have a feeling the DOSBox devs are done with
making major changes to the code pending the upcoming 0.75 release, so if you
or bruenor can figure out how to modify the save state code to be compatible
with the Gameblaster and Tandy changes and produce a patch we're probably be
good to go for the foreseeable future. And thanks again for all the work you
guys have done on this!

I was able to clean up the r4019 patch to work with r4074. I'll do some more
testing to see if it actually works with games, but initial results look good.
If I can find the time to confirm it works I'll upload the patch here.

I've attached the modified patch that applies cleanly to DOSBox r4074 named
"bruenor41_savestate_r4074_win32_mingw_v2_st-update.patch". The patch is based
on "bruenor41_savestate_r4019_win32_mingw.patch" but also includes the fix for
raiden that bruenor41 posted here:

I've tested a few games and Save States seem to work correctly. I don't really
have time for extensive testing right now, but I've attached
"DOSBox-SVN-r4074-with-Save-States.rar" which is the basic DOSBox build I
compiled for testing if somebody else wants to play around with it.

Notes from bruenor41 - (fixes to 4019 patch)

2017-09-07, 00:49
Hi, I updated save states, some things were not saved, so I took missing stuff
from daum build and I fixed some errors by myself, I don't understand why these
errors didn't appear in daum... I use more enhanced version, so I merged
changes to r4019, hope without errors. Sorry, I don't know how to create diff.
With these changes increases significantly range of games which supports
save/load states, but still not perfect. Dynrec needs more mork, it wont load
everything correctly. Seems, it needs reset, like has _x86 version.

Fixes:
  C&C1 and Red Alert - fixed segmentation faults
  Fallout 1 - fixed crash when loading states through different areas
  Earth 2140 - fixed crash
  Wolfenstein 3d + SWOLF - fixes graphical glitches
  Lands of Lore 1 - loads now correctly when loading through different areas,
  dynrec does not work here

Games what I tested for a longer time and seems to be OK:
  Warcraft 1,2
  Albion - from beginning to the end I used states and works at 100%
  Fallout 1
  C&C1
  Doom
  Might and Magic 1
  KKND
  Ignition
  Wacky wheels
  Dangerous Dave
  Bio Menace

Shortly tested:
  Settlers 2
  Realms of Arkania 1,2 (3rd part was not tested)
  Monkey Island 1
  Ultima 7 - states wont load during intro and menu, but in game it works
  Duke 3D
  Syndicate
  Willy Beamish

Games which I cant get work:
  Daggerfall

2017-09-17, 23:26
Hi people, here is newest version of save/load states. Because my knowledge of
cpu is not so good, I asked M-HT for a help. He implemented missing dynrec
cache reset. I send him big thanks. I merged that fix to version posted above.
As far as I tried, all games tested by me were loaded correctly now. Please, if
you find game what does not work correctly with save/load states, post here
it's name and your dosbox configuration. I'll try look at this.

EDIT : Save states checks which exe file is currently loaded. Might happen that
you try load save stated during intro, but intro might be another exe file
loaded by main game file. In this case, states are loaded when intro finishes
and is loaded correct exe file.

2017-10-03, 04:21
I fixed most critical issue when loading states in Alien Carnage. Another rare
situation must wait, but seems it is far enough for this game, it works well.

Edit : uploaded sources with latest fix
Please report game which wont work with states

Notes from gandhig - (ported patch to r3782 through r4019)

Thanks to ZenJu, tikalat, ykhwong and of course, all the dosbox authors, here
is an alpha version of Dosbox SVN r4019 with savestates(patches taken from this
thread), built statically(with few shared dependencies) for debian 32 bit linux
systems(tested on lubuntu only) as well as for windows.

Purists & old-timers(including myself) may please forgive.

Summary:

  1) diff uploaded by tikalat against Dosbox SVN 3782(patch-005) was used as a
     base.

  2) Added/removed certain data/data structs/POD's by comparing them between
     r3782 and r4007. Adapted to r4019 later without further changes.

  3) Under Dos Files, "LPT1" was needed in addition to "CON", "PRN" & "AUX"
     checks. Probably it was fixed by tikalat in his later patches to daum
     build.

  4) Save/Load to/from Disk code copied from latest Daum build.

  5) Aim is to reach the savestates compatibility level of tikalat's 'savestate
     patch 005' to SVN r3782 build

Tested games (i.e. no regular crash 🤣):
  a) Lure of the Temptress
  b) XCOM UFO Defense
  c) Turrican II
  d) GP2 99 by Microprose
  e) Wacky wheels (Thanks to bruenor41)
  f) Dangerous dave 2 in the haunted mansion (Thanks to bruenor41)
  g) Fallout 1 (Thanks to bruenor41)
  h) Bio Menace (Thanks to bruenor41)
  i) Might & Magic 1 (Thanks to bruenor41)

Issues/Fix needed/To Do:

  a) GP2 throws segmentation fault just after loading the saves. Issue was not
     observed in the buid of SVN 3782(with tikalat's savestate-005 patch
     applied). Got fixed automatically in SVN r4019.

  b) May not work with Dune as 'opl3gold' mode not added yet. Not sure if it is
     required or that it will crash, as Dune is not available with me.

  c) There maybe code regression due to certain new or replaced data/POD's in
     r4019 w.r.t r3782.

  d) Compile win32 build - Completed.

  e) Add MUNT support - Dropped

  f) etc.

Note:
  1) Intentionally no code was added 🤣 to the main SVN source.
  2) Dosbox SVN source/diff added in posts below
  3) Those who download the build are requested to run it first in a virtual
     environment, if possible, to avoid hard crashes.

Fix CD-DA pregap start calculation instead of clamping-to-sanity

For playback that falls in the track's pre-gap, we now make sure
to start playback at the track's actual start instead of
underflowing.

For illegal requests fall outside the legal track bounds, we no
longer "clamp our way back to sanity", and instead allow the seek to
fail (and produce the corresponding LOG_MSG) followed by passing the
failed seek result upstream, which is what would happen with a real
failed MSCDEX seek request.

This fixes a previous illegal but non-fatal seek during the intro
sequence of Betrayal At Krondor, which previously produce this log:

  CDROM: Seek requested to byte 4294875568
  which is beyond track 16's end at byte 8144976

Use Git tag description for emulator version

This change BREAKS Autoconf-based buildsystem. Only Meson and Visual

Thanks to this change, it will be easier for developers and testers to
communicate/detect the exact version of emulator.

Builds created from tarball releases OR builds from Git repo
checked out to point to an annotated tag will behave this way:

    $ dosbox --version
    dosbox (dosbox-staging), version 0.77.0
    ...

Development builds from Git repo will behave this way:

    $ dosbox --version
    dosbox (dosbox-staging), version 0.77.0-alpha-457-g6d8d10a9
    ...

Meson handles this "automagically", correctly for us via vcs_tag
function. We use it to generate version.cpp file - this way new commits
in repo will rebuild only a single file and trigger linker, but will
never result in full rebuild.

When Meson cannot obtain info version from Git, it automatically falls
back to version specified in our project function on top of meson.build
file.

Leave VERSION macro in place (it originated from Autoconf) in several
places - it's being extensively used when communicating e.g. "emulated
modem firmware version" and other fake-hardware identification.

Any builds created with Visual Studio (Release and Debug builds) will
use hardcoded version string for VERSION macro and hardcoded version
string DOSBOX_DETAILED_VERSION for all the places where we want more
info. This macro defaults to string "git" and is being overriden with
output of "git describe" on CI.

Also, adjust --version copyright message for readability and to better
fit into 80 colums.

Fixes: #543

WIP test if MSYS2 builds are ok

Update DOS_SetFileDate with non-deprecated calls

Context:
 - Originally implemented in ykhwong's fork of DOSBox.
 - gulikoza and FeedingDragon updated the patch for DOSBox SVN, and
   added support for internal COPY command.

Message from author:

I took the freedom to adopt this to trunk.

The original patch(es) have some problems, so I needed to rework it
a bit. Main problem was that they work on file names stored in
DosLocalFile Class. These however are mangled DOS style 8.3 names,
not the orignal filesystem names.

(for example DOSBOX~3 instead of DOBOX-SVN-SRC). Trying to open
these to set the time of course fails.

Also the modifications to implement this were both invasive and not
conformant to the coding style used elsewhere in the files. The file
system directory path of the file needs to be stored in the class
and the original implementation does that without copying it,
leaving a reference to the original string.

What however works well and is both less invasive and memory intense
is to set the file time using the still open OS file handle.
Unfortunately Linux does not provide futime(), but luckily there is
an alternative available on all modern operating systems: futimes().
This should work with linux >= 2.6.22, NetBSD, FreeBSD , and MacOS.
For Windows I use the SetFileTime() on the handle as in the original
windows patches.

Care is taken to flush out any high level buffered file data, before
the time is set. Otherwise the FileTime would be set to the current
time when the file is close.

So this patch should work on any modern operating system - The only
thing open is OS/2 - which I doubt is used for other then academic
research any more .

I not sure and I cannot test, but even OS72 should have _futime().
Someone still working on this can try to implement it, it should be
simple.

I tested the attached pach on both linux (x64) and Windows (X64,
cross-compiled using a very recent mingw on SuSE) - both work
correctly.

This now allows DOS games patching without complaining.

WIP Initial integration of gettext

- Convert few messages to new API
- Create template file (dosbox.pot)
- Create tiny translation file for polish (pl/dosbox.po)
- To test: compile dosbox.mo (using e.g. poedit), and place it in
  ./pl/LC_MESSAGES/dosbox.mo
  then run:

      LANGUAGE=pl ./src/dosbox

- TODO: gettext converts to US-ASCII (removes diacritics) (good!),
        but dos can't show them - synchronize gettext conversion
        with used codepage (e.g. 'keyb pl` loads codapage 852, so
        so when recompiled with CP852 instead of US-ASCII, the polish
        letters are perfect) - make it switch in runtime

Overscan borders

The old version is not working that well with new render
implementation. Here's completely new approach. It's not
blended border anymore. It is not as universal as the old
version -- currently works only with output=surface, it also
requires forcing fullscreen size to be bigger than video
mode used by game (no such limitation for window mode).
While it is less universal than the old one it does look better.
The controlling option in dosbox.conf is different. Use
overscan=<width> in [sdl] section.
This implementation is much cheaper and simpler than the old
one, near zero performance cost even with frequent border
color changes. For this reason it is compiled
unconditionally - C_OVERSCAN is not used anymore.

WIP Try to silence some static analysis issues

Static analysis complains about default switch case, when in reality it
seems like it cannot happen (to be investigated).

it seems like rm_mod is a single byte, rm_eai is 3 bits; which would be
too much. case covers *subset* of 5-bit values.

Implement 3dfx Voodoo emulation

This is an updated patch against current svn.

- fixes minor compiling issues
- fixes a major video memory leak in Quake2 and Descent2

Quake2 uses sort of dynamic textures for realtime lighting, changing
existing textures thus invalidating textures cache and forcing to
reload them.

Descent 2 writes to existing textures for animations and fonts.
The fix adds a glDeleteTextures in function voodoo_ogl_texture_clear,
which is called when a texture is invalidated due to a write.

There is still a performance issue because of texture caching during
explosions or gun firing.
