Title: OS/2 - ArcaOS - Native Games
Post by: Martin Iturbide on February 24, 2019, 03:46:29 am
Hi

These are the SDL games I checked to have some issues:
- 2 Pong (http://hobbes.nmsu.edu/h-search.php?key=2pong)       0.6      SDL / SDD   GNU GPL      *** Require SDD
- Amoebax (http://hobbes.nmsu.edu/h-search.php?key=Amoebax)   0.2.1   SDL              GNU GPL      *** Old SDL12.DLL
- Barrage (http://hobbes.nmsu.edu/h-search.php?key=Barrage)            SDL / SDD   GNU GPL      *** SDD dependency
- Dave Gnukem (http://hobbes.nmsu.edu/h-search.php?sh=1&button=Search&key=Dave+Gnukem)   0.56      SDL / SDD   GNU GPL             *** Requires SDD
- Fish Fillet (http://hobbes.nmsu.edu/h-search.php?sh=1&button=Search&key=Fish+Fillet)   1.0.1      SDL              GNU GPL      *** No run
- Lopan (http://hobbes.nmsu.edu/h-search.php?sh=1&button=Search&key=lopan)      0.9      SDL / SSD           GNU GPL      *** Require SDD
- Marryampic2 (http://hobbes.nmsu.edu/h-search.php?key=Marryampic2)   0.6      SDL / SDD   GNU GPL      *** Requires SDD
- Primate Plunge (http://hobbes.nmsu.edu/h-search.php?key=Primate Plunge)      SDL              Freeware           *** OLD SDL12.DLL / Hangs
- QNetWalk (http://hobbes.nmsu.edu/h-search.php?key=QNetWalk)   1.4      SDL /KSDL12.DLL GNU GPL   *** OLD SDL12.DLL
- Rocks n Diamonds (http://hobbes.nmsu.edu/h-viewer.php?dir=/pub/os2/games/puzzle&file=rocksndiamonds-3.2.4.zip)   3.2.4 SDL              GNU GPL      *** Can not load Joystick

If someone wants to test these with the latest SDL and make those works without the SNAP driver, please let me know.
For the moment these ones looks like good candidates to be recompiled with the latest SDL.

Hi Martin,
I probably have the environment to rebuild these and am willing given the spare time.
Questions,
What do you mean by the latest SDL? The RPM version is missing some of its supporting DLLs. Need at least sdlgfx.dll, sdlimg.dll sdlmix.dll, sdlnet.dll and sdlttf.dll (names might vary, eg sdl_gfx.dll). I'm also unsure if the RPM version was built with OpenWatcom or GCC, or if it matters. I guess the source is available to look at :)
There is also SDL2 along with corresponding versions of the above DLLs. As SDL is depreciated, perhaps if simple, we should be using SDL2?
There's also the problem of missing source code. I looked at the source of Lopan IIRC, it needed more then simply recompiling, including decisions which way to port, the Windows way or the Linux way. Where to keep configuration files, high scores and such.
Others such as Rocks'n'Diamonds should just need a small makefile patch (it was the first thing I ever ported, X11 version), but might as well as update to the latest source. Rocks'n'Diamonds is a good example of a game that really needs the joystick to play.
Now there's the question of whether to link against libc+libcx or lbcn.

More complications. I looked at https://www.artsoft.org/rocksndiamonds/ (https://www.artsoft.org/rocksndiamonds/) and wonder how much of the new stuff can be simply supported? eg Drag'n'Drop. Might be stuck on older versions.
Title: Re: OS/2 - ArcaOS - Native Games
Post by: Martin Iturbide on February 24, 2019, 02:02:21 pm
First of all, thanks for the help Dave.

What do you mean by the latest SDL?
I mean using SDL-1.2.15-20160303.zip (http://hobbes.nmsu.edu/h-viewer.php?dir=/pub/os2/dev&file=SDL-1.2.15-20160303.zip)  and/or SDL2-2.0.4-20160225.zip (http://hobbes.nmsu.edu/h-viewer.php?dir=/pub/os2/dev&file=SDL-1.2.15-20160303.zip), without mixing older/other version of the SDL runtimes to run an specific game. I want to aim to have one version (latest ones not older) of SDL libraries installed on the system.

At the moment I'm ignoring the SDL runtimes files on the rpm repository.

There is also SDL2 along with corresponding versions of the above DLLs. As SDL is depreciated, perhaps if simple, we should be using SDL2?
If that can be possible without big efforts on changing the game source, it would be great !!

Now there's the question of whether to link against libc+libcx or lbcn.
I would go with the rule, which is the latest one first (as version release), and later which one works.
It looks to me that Bitwise is going to put more efforts on "LIBCn" from now on, I would vote for LIBCn. Am I understanding this announcement right (https://www.os2world.com/past-news/80-software/22424-libc-next-klibc-fork-released.html)? . Are the libcn runtimes available on the rpm server? In case that LIBCn is not working to run the game, then we use the older one :)

Dave, if you succeed compiling some of those games, please let me know if you can put the source code somewhere (like github). I'm even having a hard time finding the original source code of some of these open source games. I'm trying to put that source code here (https://github.com/ossgames/) (it is not OS/2 source code it is the original one)

Here's 2Pong. I pushed the changes to Github. Mostly I fixed warnings and added some OS/2 specific LDFLAGS (-Zomf and -Zbin-files). The LDFLAGS would need commenting out on other platforms
Lightly tested.

Sorry, I slipped the topic since I want to focus on my testing of ArcaOS - OS/2 native games (or natively compiled games for the platform).

Thanks Dave, I will be testing 2Pong.
I'm also trying to fins some source code of the other SDL games that are not running or have a SDD dependency.

Hi

Was someone able to run this game:
- Fish Fillet (http://hobbes.nmsu.edu/h-search.php?sh=1&button=Search&key=Fish+Fillet)   1.0.1      SDL              GNU GPL      *** No run

It does not run for me. I had run it with "fillets >stderr.txt 2>Whatever.txt"
and I get this error:
Quote
main.cpp:117: ERROR init file not found; path='/fillets/share/games/fillets-ng/script/init.lua'; systemdir='/fillets/share/games/fillets-ng'; userdir='C:\Home/.fillets-ng'; hint='try command line option "systemdir=path/to/data"'

I tried copying the share directory of this game on several locations but I still can not make it run.

Any tips?

Hi Martin,

Have you looked at the OS/2 games produced by Daniel F Valot http://dvalot.free.fr/OS2programs.html (http://dvalot.free.fr/OS2programs.html)  He has some nice disk programs there as well.

Hi Ivan

Yes, I have those games on my map but it is good that you remind me, because I have to check if there are newer versions that I missed for the OS2World Gaming Site (https://www.os2world.com/games/).

Hi

By the way, I'm taking some time to update the OS2World Gaming Site, because since the 2012 HDD crash some files where missing.
The action and adventure categories had been updated: https://www.os2world.com/games/index.php/native-games (https://www.os2world.com/games/index.php/native-games)

I'm missing some files from:
- BLP (https://www.os2world.com/games/index.php/native-games/action-2/29-blp)

Ouch... too much work.

Action, Adventure, Board, Cards/Dice, Educational, Other categories had been updated, specially the download links. I'm also reorganizing and renaming the files without any respect to the 8.3. It is just a way I prefer, since I have a mess with different versions.

I updated  the links of the native games of the OS2World gaming site. (https://www.os2world.com/games/index.php/native-games) It is not perfect, but I can say not it is decent.

I will be also update the site with some Qt games I'm missing in this month.

Try doing SET VESADLL=VESA_IBM or SET VESADLL=VESA_ALL in your full screen session before running os2billy. Can also try vesatest.exe
Still doesn't quite work here. Vesa.txt includes instructions to patch your video bios if you're really adventurous.
PS Running "markexe NOTWINDOWCOMPAT os2billy.exe" will force it to open a full screen session.

Hi

Just in case I created the "ONE HUGE FILE OF WARP GAMES (https://archive.org/details/OHFOWG)", where I put all the OS/2 native games (open source, shareware, freeware) I was able to get and organize them alphabetically. It is a 1.33GB size file, it may not make sense, but nothing makes sense these days :) 

Not everything is working, and it may not be complete, some icons are missing, maybe there are thing that you will not like, but feedback is welcome to improving it.

Hi

I think it is finally time to upload the OS/2 games source code to github. I don't known why I saved that for last.
- OS/2 native games and source code ported to OS/2 are being to be uploaded to: OS2World Github (https://github.com/OS2World)
- OSS Games that I was able to find the source code, but not the OS/2 changes to: OSSGames Github (https://github.com/OSSGames)

The idea of OSSGames Github (https://github.com/OSSGames) is just to try not to lost the source code of some games that had been ported to OS/2. The porter never share the OS/2 part of it, and I also want to see if I can organize myself to try to port a game myself.

Hi Martin,

You need to check that zip because here all I get is an error message, see attachment.  Also last night the torrent didn't work.

Hi Ivan.

Thanks for giving it a try. I did a test on a different machine (windows) and tried the torrent  from Internet archive (with Bittorrent tool),  downloaded the file, open it with PeaZip (it took some time) and I was able to see the files and even open the readme to test. This quick test worked for me. But I will need to keep polishing the file, I found some games I was missing.

Hi

I found this pascal source code, I'm not sure if it is complete, or if it belong or not to a game called MasterMind for OS/2.
Can someome please take a look at it?

Regards

Title: Re: OS/2 - ArcaOS - Native Games
Post by: André Heldoorn on April 21, 2019, 06:53:51 pm
Alright, but only because I'm some ome.

The Sibyl-files are somehow related to a Mastermind for OS/2, but the *.SPR files seems to be nothing but a project/"container" file or makefile. A project file of an IDE.

Dependency36's file seems to be missing. So does any meaningful PASCAL code in the *.PAS files.

I don't have Sibyl, so I don't know if it will understand U_about.pas' "{Private Deklarationen hier einfügen}" (German, "Private declarations here insert", i.e. insert private declarations here). Regardless of that, at least of of the missing and possibly most important source code file may be MAIN1.PAS.

You may have received a copy of a project directory, but not of a directory of e.g. MAIN1.PAS.
Like receiving a back-up of Sibyl's C:\Projects (C:\Projects\SibylProjects\HelloWorld.SPR), but not of the file C:\HelloWorld.PAS of that Sibyl project.

If you are lucky, then your source has got a back-up of all missing non-Sibyl source files, like MAIN1.PAS.

There is a German Mastermind/2. If this is supposed to be that Mastermind/2, then you may also be missing e.g. the IPF source file of the *.HLP files (possibly 2, German and English).

Either way you can open and "study" the *.SPR text file, to see what's mnissing for sure. I assume it's a Win-OS/2 INI-style Sibyl IDE project file.

Post by: Martin Iturbide on April 21, 2019, 07:45:59 pm
Thanks for the reply André.

So, it is incomplete and useless, right?

Just in case, I'm almost sure that is it not from the MasterMind/2 (Rene Auberger) (https://www.os2world.com/games/index.php/native-games/strategy/319-mastermind-2), on his archived website (http://web.archive.org/web/20090728202927/http://geocities.com/r.auberger/), he used to share the source code but it was C. I'm still trying to get those files.  (mmind14-source.zip, ../r.auberger/v14/main-c.zip)

I also found "Master Mind for the OS/2 2.x Presentation Manager" by Peter Wansch, but I'm not sure is also from that.

I also found "Master Mind for the OS/2 2.x Presentation Manager" by Peter Wansch, but I'm not sure is also from that.
Strictly it's useless because it's incomplete. Nevertheless the SPR file shows which files are missing, so it's only useless if we cannot obtain those specific missing files anymore.

Later stand-alone games of Wansch became a component of the Entertainment Pack for OS/2.

"ProjectName=E:\PROGRAMIEREN\PROJEKTE\MasterMind\Mastermind.spr" indicates that the author speaks German. The previous quite could have been inserted by any German programmer (e.g. some template of Sibyl itself), but the user has created the subdirectories "PROGRAMMING" and "PROJECTS".

As such Wansch qulaifies as a canddate. There's a Vienna and Austria in his MASTER.EXE (indeed Master Mind, with a space).

If you have an EXE produced with Sibyl, then you could try to open that Sibyl EXE and Wansch's MASTER.EXE with E.EXE or a hex editor to check if the "fingerprint" is about the same. Typically readable text, and where it can be found. MASTER.EXE doesn't contain "sibyl", but e.g. a lxlited pathetic game written by me contains the text "SETUPARG.ASM". That text me be specific for IBM VAC. An extreme positive sample is opening the EXE of Tablica/2 version 1.20 with E.EXE, and next guess the programming language and what the source code was. If I open a FIREFOX.EXE with a hex editor, then page 1 shows a clue ("OS/2 executable
module built for kLIBC v0.6.4+") which indicates that FIREFOX.EXE wasn't produced by a Sibyl compiler.

Please note that a non-negative possible Sibyl footprint of MASTER.EXE doesn't imply that Wansch is the German speaking author of your project files. It just is more likely if Wansch used Sibyl (too). But his final product (now) has that possibly different name, "Master Mind".

It builds easy but crashes I believe while initializing the video.
To build, make sure MAKESHELL=sh.exe is in your environment.
Edit the parent makefile in the root directory by adding
Code: [Select]
-Zomf -lcx -Zmap -Zbin-files
to the echo LDFLAGS line at 76, then do make
Should build and leave a xrick.exe in the root directory. Look at the trp report. Make sure the sdl dbg packages are installed as well as the devel ones.
xrick --help does work.
You can edit include/config.h to turn on debugging, change the line #undef DEBUG to #define DEBUG and it will print some stuff.
Do a make clean before rebuilding.
Here's my binary with debugging on and sound disabled.

Hi

Thanks Dave for giving it a try.  Here it is the TRP file I'm getting.

Are you using Netlabs RPM SDL to compile it (SDL_develop) or are you using the Digi's SDL  (http://os2.snc.ru/product-SDL.html)to compile it?

Regards
Title: Re: OS/2 - ArcaOS - Native Games
Post by: Dave Yeo on July 03, 2021, 07:40:17 pm
Yes, it is the same trp. I used the Netlabs RPM to compile, I'll try Digi's later.
Title: Re: OS/2 - ArcaOS - Native Games
Post by: Dave Yeo on July 04, 2021, 06:16:26 am
Digi's SDL trps the same.
What I think the bug is, is that it queries the list of possible full screen video modes, which here just returns one, 1680x1050 in my case, and then tries to go through the list of video modes to make sure they will work. At this point it crashes when trying to load the 2nd member of an array of one.
I'm not really a programmer and can't see the simple fix, I'll think on it some more.
The broken code is,
Code: [Select]
  else {
    IFDEBUG_VIDEO(sys_printf("xrick/video: SDL says, use these modes:\n"););
    for (i = 0; modes[i]; i++) {
      IFDEBUG_VIDEO(sys_printf("  %dx%d\n", modes[i]->w, modes[i]->h););
according to the trp report. the crash happens here (perhaps actually the 2 lines above?)
Code: [Select]
      if (modes[i]->w <= modes[mode]->w && modes[i]->w >= SYSVID_WIDTH &&
          modes[i]->h * SYSVID_WIDTH >= modes[i]->w * SYSVID_HEIGHT) {
        mode = i;
        fszoom = modes[mode]->w / SYSVID_WIDTH;
      }

Edit, pointed to crashing line.

Hi.

While porting PrBoom+, I fixed some initialization bugs. The fixes are pushed into the BWW repo.
Perhaps, if you compile the repo version, it fixes things.

Does anybody knows where can I get "VORBISFI.DLL" ? It seems that the latest libvorbis on the Netlabs RPM does not has that file.

    for (i = 0; modes[i]; i++) {
      IFDEBUG_VIDEO(sys_printf("  %dx%d\n", modes[i]->w, modes[i]->h););

I actually don't like the for cycle written above: (reported below)

Code: [Select]
    for (i = 0; modes[i]; i++) {

It implies that the cycle should stop after cycling through all the items in the "modes" array but I feel this should be written better asking for the actual length of the array. Don't know if this is C-99 or some more modern incarnation (this code uses lambda expressions so I assume is pretty modern, and I'm no expert in this) but this writing leaves me perplexed.

Problem is, that you don't know the size of array in C/C++. That is why APIs almost always give you an list size or a 0 terminated list.
The latter is what this "for" is assuming. But we have a field "num_display_modes" in the display structure, that could be used.
But in BWWs version, I fixed an init error in the display structures, which should be applied to Digis version, if not already done.

I didn't find your fix.

Hi

I have a noob question about SDL development. For games that had been developed with SDL 1x, is it possible to recompile those with SDL 2.x? or all the game code (like functions calls, etc) will need to be changed to use the SDL 2.x instead?

Regards

Thanks, guess I'll try to build it.

Quickly looking, it seems the video handling has changed, things like no more full screen, rather a large window, perhaps with no menu etc. And the keyboard input also has changed, might mostly affect Unicode, along with changes in the event queue. Seems a lot of games are focused on the hardware rendering.
This is the page I read, https://www.doomworld.com/forum/topic/86368-sdl-1x-vs-sdl-2/ (https://www.doomworld.com/forum/topic/86368-sdl-1x-vs-sdl-2/)

Has anyone looked at how hard it would be to add USB Joystick support to SDL? I know next to nothing about it except a little experience with old style joysticks.
Seems basic support would be 2 axis and 2 button support, for many games even joypad support where a couple of buttons and the axis is basically binary or trinary, would be nice.
I ask because I recently revisited Rocks'N'Diamonds (our SDL mixer needs mod support), which reminded me how much more fun it was to play with a joypad rather then the keyboard.

I haven't looked into it at all, but I'd assume any support would use libusb (which we have) so surely it wouldn't be that difficult.

Cheers,

Paul.

I have thought about it, and it is on my bucket list. The linux drivers use the hidapi library (it is even part of SDL2). I was thinking about using that code for OS/2.
