What Does It Take To Port 16-Bit Windows 1.0 Applications Into Native Windows 11 Programs?

Windows has been around for 36 years now, and it's changed a lot since it's early days. However, one question I had to wonder is: what does it take to port a legacy Windows 1.0 application to the modern day. After all, computers in 1985 were 16-bit, while modern computers are now 64-bit. For those of us who lived through the 90s, you'll remember that upgrading to then new Windows 95, and NT 4 were very much a big deal.

For the sake of my curiosity, I decided to find out. Starting with the example applications from the Windows 1.0 SDK, i started by porting them forward to Windows 3.1 and modifying them to compile under Microsoft Visual C++ 1.52. After ensuring I had working project files, I then ported then to Visual C++ 6 under Windows NT 4. This provided a 32-bit baseline, and let me resolve API issues such as changed to hPrevInstance, and the removal of certain non-Ex variants of functions from 16 to 32 bits.
This then extended to porting to Server 2005 and Visual Studio 2005, where I did an initial x64 port, and tried to create an Itanium based ported, but failed, due to Microsoft's annoying policies of gating off developer tools behind an absurd paywall.
After gnashing my heath, we hopped ahead to Windows 11, and Visual Studio 11, where, after importing the project files, we had everything running just fine on 64-bit platforms. This of course encouraged chat to make me take it further. First I ended getting the applications running on WINE, then we hopped into ReactOS, OS/2, and well, we transcended the world of x86 programming entirely, and ended up on NT4 on MIPS, which involved using a special edition of Visual C++ 4 to compile the binaries for the never realized non-x86 world.
Afterwords, we wrapped itup, and I decided to re-edit this stream into a full fledged video, with the third NCommander in Realtime event.

I believe this is why Cardfile had custom assembler disk DOS routines: "createbitmap may have caused disk swap, make user reinsert disk" -- it relied on the functionality to simulate a two-floppy system on a single-floppy system. Cardfile was not written to read the entire file into memory because it ran in real mode and each card could have a bitmap up to 64k in size. You could have replaced with stdio C calls easily.

@NCommander 2 года назад

Good catch. There's actually a few other places where it uses assembly for some string manipulation functions. It would be straightforward to rip the ASM for C code, but it would still probably be 1-2 hours of fiddling.

That's game consoles, where, historically, the software is directly driving the hardware and each version of the hardware is commonly not even the same CPU instruction set, let alone memory model, graphical features, etc. Microsoft did the work and had a team working for years on getting old games running correctly on new systems at no additional cost to the user, while Sony and Nintendo instead required the developer to do the work to create (and sell) the port. The latter certainly makes more sense to investors, so I can hardly fault them for that, especially when it was never an expected feature before Microsoft.

This reminds me of a utility I needed which was available on the Internet only as a C source file. On double-clicking the source file, it opened in Visual C++ 6.0 (which I had installed on my XP PC), and it compiled and ran just fine after changing just one line. After the fact I realized that the source file was actually written on and for the Amiga. It still ran happily on Windows XP. However, it was a command line application with no GUI which, as far as I remember, only served to convert one file format to another.

Late to the party, informative! I had a range of in-house 16-bit monitoring applications I'd developed in Delphi and ported them to 32-bit back in the day. Although Borland had done a fantastic job of allowing you to port existing applications, I'd made extensive use of functions directly calling the Windows subsystem. Suffice to say, it was still a chore to successfully recompile and I also ran into you problem of functions that didn't exist (or were renamed, took different size parameters etc.). One of my _"just for fun"_ projects I made was a Delphi custom control for the Task Dialog (introduced in Windows Vista) for Delphi 7. Besides supporting the underlying native dialog, I built a complete emulation of the dialog for earlier Windows OS's (well, Windows 2000 & XP) that necessitated coding *more* custom controls. Yeah, you could say I got rather carried away.

So I took the simplest path - I made a screenshots of the native app, moved the icons to GIMP, set transparency with color to alpha tool and bang, my app looked exactly like the native one without a single pixel drawn by hand. As for the timing - if whole process took you about 8 hours, this would probably take you no more than 30 minutes, downloading and installing GIMP included ;) Yes, I like GIMP ;) And I can't draw at all, I just use GIMP to build icons from images.

I don't think that's true anymore, if it was ever really true? I don't know about NextStep, but Mac OS 1 software was written in Pascal, officially. You should have been able to use C but it would likely not be, and some point you would have to port that to C. But let's say you've gotten to a more popular "classic" Mac OS 7, that would port to the OS X Carbon API pretty easily, since that was the intent (probably about the effort of windows 16 to 32bit at worst). The problem is,regardless of Next or Classic Mac, that the, as far as I know, only UI API of 10.0, Carbon was removed in OS 10.15 Catalina, and Carbon to its replacement Cocoa is *not* an easy port. You could probably also hit things like the permission hardening in various versions. Apple, for better or worse, have not been as backwards compatible as Microsoft.

@@SimonBuchanNz note the capitalisation and spacing, they’re actually only referring to OSX under the new name, not the Classic OS. And even core system UI elements like the colour and font picker are unchanged from NeXT, Quartz is a descendant of Display PostScript (and can still, with the right interpreter software, export the entire screen into a PSD with every window its own layer; just like NeXTSTEP could save and send a PostScript print document of the GUI to a connected printer) so I wouldn’t be surprised if some third party applications can still work with minimal tweaking. OSX has Swift now but last I checked (which was a few years ago) there was nothing stopping you from using legacy Objective-C code.

@@kaitlyn__L they said "from the first next step os..." so, no, I don't think they were saying from the first branded as "macOS" (which was only somewhere around 10.12ish, IIRC? Hardly impressive if it was what they meant) Yes, I'm aware of Quartz. It was introduced in OS 10.0, and isn't a common or sufficient API to target: it's a 2d graphics library, not a UI library. (Or you're talking about the compositor, thanks Apple for the overloaded name). You *might* be able to compile a very specific type of application with entirely custom UI components on 10.0 up to 11.x, but I'm very suspicious. On the other hand, it's very likely that many Windows 95 samples compile on current Windows (modulo compiler fixes in practice), and that Windows 1.0 samples need only minor changes. Again, this isn't *intrinsically* a good thing, the API is often quite bad in comparison when ignoring the history (11 parameters to CreateWindow!?), but it's the users that really pay the price: losing access to older software, vs worse quality on average for native apps. Not sure why you're bringing up iOS, it's lineage isn't that relevant or interestingly long here.

@@kaitlyn__L You see NeXTSTEP's influence all over modern macOS with so many of the APIs starting with "NS". I know Apple is strongly pushing people to Swift, but Obj-C still has its place - I liken it to how even Python programmers sometimes use C-based libraries for performance or compatibility reasons.

8:05 System.fon is a variable-width raster font, sadly. When you installed high-resolution video drivers on Win3x, they would often have a "Large Font" variant of the driver, which swapped system.fon for an equivalent with larger glyphs. Pretty sure 3.x, 9x , NT, 2K and even XP used raster fonts for all UI widgets, ClearType on XP notwithstanding. What a shamozzle! :D

You're supposed to make sure you have sizing to work regardless of fonts (this is one of the main reasons why German was one of the first languages that Microsoft releases betas for since statistically, it's one of the more verbose languages by character count.

What's interesting about coding is how there's 1000 ways to do the same thing. This really shows how amazing Windows is, there are games and programs from Windows 95 that I can literally just double click and run, and it runs. Somehow, it just works. Whereas there's other programs made for just a different version of the same windows that will throw a fit if anything changed.

Lol Linux requires no changes, you can literally bring a statically compiled executable from the earliest version to today and it will run fine. Linus has committed to never breaking userspace. Generally tools to build software are backward compatible as well.

Why not use #define macros to generalize all the porting, and make via conditional compilation a way to compile any source files on any compiler version and target bitsize. Even resource files and assembly files have support for it possibly at least in the more modern tools. But the macro approach makes your translation procedure much more well documented, generalized and faster, less mistake prone and flexible. Porting the interupt calls sounds like a by hand procedure when moving to 32bit. MASM is abandonware and I think you can safely find it as such. Using Borland for the visual assets is a great idea or even writing a tool to parse the old files and translate them yourself, given graphics files are not too complex. Anyway cool project, well done

@arunraman6630 2 года назад

Had the same exact idea regarding using macros

@bigalejoshileno 2 года назад

MASM is not "abandoned", but the old linker it is. Strictly speaking, all interrupt stuff can be moved just from binaries and linked executables, but no one knows enough about microsoft obscure win16/32 apps. One of the most annoying things are the timer calls from old apps, most are only delays and modern cpu's heat a lot wasting time in those loops.

@NCommander 2 года назад

Honestly, the main reason I didn't was because this topic was virtually undocumented. There are some pointers in the VC++4/6 documentation, but it wasn't compherensive so I had no idea how complex this would be. Also, for comparsion sake, its easier to see how each one is different on Git.

@gregorymorse8423 2 года назад

@@NCommander it's sad microsoft has not preserved the old MSDN documentation. I remember CDs and DVDs full of it years in the past. Now that the job is done, you are right, some diffing could easily convert the work you already did to macros and conditional compilation. In a way, unless still needing to support old Windows, it just muddies up the code. But just for the fun of having portable source, might be worth it, as well as to aid future projects

You missed a trick. There was actually a library that mapped the Win16 API onto 16-bit Presentation Manager, Micrografx Mirrors. You could have used that and built an actual (16-bit) OS/2 program.
