Sandboxie went GPL3!

I’ve been using Sandboxie for a long while to run all those questionable downloads on Windows. It’s a great light weight sandbox (as the name implies) for running random downloads, or even going to questionable websites as Sandboxie does a great job of isolating processes, and their filesystem access.

It’s not been all that cheap, but I felt it was worth it. I went to check to see how much it is as the conversation had come up on discord, and it turns out that Sophos had bought Sandboxie, and opened up the source code!

The downside is that there will be no further official development of the product. So I guess at some point I’ll have to break down and get a signing cert and re-build it if I want to keep using it.

Last version is locally mirrored here, as I understand it’ll be deleted soon enough.


Anglofying & running Japanese Lemmings for Windows

On one of my later trips I picked up this fun title, Lemmings!

And looking at the back of the box, what fun it contains!

Support PC-98, Epsons, IBM’s, IBM PC/AT.. Probably FM Towns as well

One interesting thing about 1995, is that with the rise of Windows 95, this marked the end of the specialized PC market in Japan. Just as WING/Direct X basically killed off the DIY driver/extender environment on MS-DOS, by being able to abstract the hardware it removed any meaningful difference between an EPSON PC vs a PC-98, FM Towns, or even the lowly IBM AT/386.

This being a Win32 includes both WING & Win32s. A perfect snapshot of an early Win32 commercial game circa 1995, as you needed to cater to that massive Windows 3.1 install base, although so many were rushing to Windows 95. Naturally this also means that the setup program is a Win16 app, once more again to preserve that bridge of the Windows 3.1 & Windows 95 world.

Well the obvious thing to do is just install it on a legacy 32bit OS, and what better than Windows XP?

Lemmings happily running under Windows XP via VMWare.

Now to run it on something like Windows 10, it’s just a matter of copying the WINLEMM.INI into %sysroot%, along with placing a copy of WING32.DLL into the %sysroot%\SysWOW64 directory and you are good to go!

Japanese Lemmings on English Windows 10

Sadly the character encoding in Windows is still really lacking and doesn’t render all that great. However that had me thinking as almost a decade ago I did find a demo of Lemmings for Windows. Could it be possible to just overlay the executables & DLL’s to produce an English commercial version?

Surprisingly the answer is yes. I wasn’t sure what to expect, but it’s as simple as that!

The game is mostly playable, some parts are just coded to run as fast as possible, as no doubt nobody was imagining 1+ Ghz machines. So the intro, warp & suicide are almost instant.

It’s something to keep the kids entertained for a day in recent events. It’s been a LONG CNY.

Cross compiling SDL 1.2.15 for ARM Win32

I was getting this fun error:

C:\proj\ss\SDL-1.2.15\VisualC\SDL>link /dll -out:sdl.dll *.obj winmm.lib dxguid.lib gdi32.lib user32.lib advapi32.lib dxguid.lib uuid.lib dxguid.lib Version.res

Which was NOT easy to track down. Thankfully while amputating and chasing the origin of GUID_Key, I ran across this:

I have read various texts that state you must

1#define INITGUID

And yes, you do!

In the file SDL-1.2.15\src\video\windx5\directx.h I just added it to the top, and now it’ll build the hacky DLL!

Maybe it’s something for Visual C++ version 19? I don’t know.

Anyway the advantage is now I have full audio for DosBOX!

Luckily updating binaries wasn’t too hard.

Congruent (Toolbusters) GCC 2.4.5 for Windows NT

Perhaps one of the more interesting, if not abandoned GCC ports.

It’s from 1994 (although they apparently had earlier), and it’s just enough binutils & gcc to compile stuff for Win32.

I stumbled onto the directory while looking for the source code to the ‘top’ program, which incidentally can be found here. In hindsight the name ‘top’ is pretty terrible, as looking at the ‘top program for Linux’, well you are going to find all kinds of crap, and surely not top.

The files gnu-bin.tar.Z and gnu-lib.tar.Z contain enough binaries for GCC 2.4.5 C/C++ and ObjectiveC, along with GAS and what purports to be a linker, although I think it just prints the flags to MS Link that you’d need.

And as mentioned in this post, by Juha Inkari, how on earth do you use this thing? Well thankfully in the future we have access to more stuff, so I decided to throw MinGW at it, and see what happens.

I’m using the Linker & LIBC from Fortran PowerStation 1.00 with the linker update.

There is no source diffs, patches, or anything really.

Is this useful? I suspect not. Thanks to RSXNT there is easier ways to get much older versions of GCC… Although I guess it speaks more so to this port using OMF objects.

Living with ARM for a week

So after the crazed purchase I made a few weeks ago, I returned from Japan, and was able to unbox and use the machine I’d been wanting for a while, a non x86 Windows laptop!

The NovaGo has a Snapdragon 835, and my phone, the ASUS ROG phone has the 845. Yes for this week, my cellphone actually has the stronger processor than my computer. Honestly this is almost an unthinkable situation! Although I haven’t been using my phone as a desktop substitute this week. It’s amazing how MS screwed up 10 on the phones, and Continium.

By default it comes crippled with this ‘S’ mode Windows, which hearkens back to the Windows RT launch, with the difference that it’s a quick trip to the application store to unlock Windows 10 Professional. It’s a free download as it should be, and it doesn’t even require a reboot!

Build quality isn’t so bad, the screen folds all the way back to make the machine into a ‘tablet’ although I don’t like that mode so much, it just feels wrong to wrap a keyboard around a monitor. However if you have rambunctious young kids, it’s great as when someone went running by me flailing their arms around like a while animal, when they struck the laptop the screen could easily fold back 180 degrees. Yay.

My first thing to do after setting up Office and VMWare VDI was to install the Linux subsystem, and Ubuntu. it’s exactly the same as it is on x86_64, which is great. And this let’s me have the best of both worlds, just like x86_64. As much as I dislike stumbling around with that aborted child of Pascal & Fortran (Python) at least I can run it under (mostly) Linux to get something close to like the production environment.

The C/C++ compiler is actually all cross tools. I wanted CLI only stuff because I like torturing myself, and it required a few GB of downloads. The good news is that the latest Windows 10 SDK does support GDI/CLI apps, so no crazy SDK hacking required, unlike back in the Windows RT days. Oddly enough the Taskforce 87 interpreter runs fine, but nothing else does.

I did a horrible job at hacking up SDL 1.2 to at least run (kind of, the audio doesn’t work, and it’s all WinDB *EDIT I got it fixed!!!) I got a few things up and running, including DOSBox and FrontVM. One thing that greatly helps is that i386 binaries ‘just work’. Honestly you wouldn’t even know you are running them when you are. Which made hunting down the ARM64 version of Chromium Edge kind of difficult to find. There really needs to be a more apparent way to tell them apart, if anything for battery efficiency.

As pictured, SQL Server 4.21a runs just fine, again you wouldn’t even notice. Same for Visual C++ 1.0 & FORTRAN PowerStation 1.0.

Again the audio in my crap SDL build doesn’t work, so DOSBox is silent, and without Direct X, the text mode is tiny. Oh also, there is no OpenGL in this version of Windows dev kit for some reason. Running ssystem is ungodly slow. Also the default optimizations seems to be Os, optimize for space, and on this ASUS I have to say /Ox is way way faster. DooM is quite playable on DOSBox when build with /Ox, unlike /Os.

For me, I spend most of my day to day in Office, and VMWare VDI, connecting to secure networks. So I’m just one step above a terminal. Which I guess is kind of sad, but this machine more than fills that roll for me. The 120GB of storage is tight. This isn’t a development machine persay, nor is it something to download tonnes of data to, it’s a lightweight machine where it’s strength is the built in 4G modem, and when running ARM software the longer battery life. To me the biggest drawback is that the keyboard isn’t backlit. Even though I touch type, I didn’t realize how much I’d grown used to it for casual use.

I guess it’s a hard toss up from this and a PINEBOOK Pro, I think most readers here would prefer the Pinebook, for all it’s openness, although I still like the idea of being able to copy over the Win32s version of Lemmings, and it just running. For me I kind of like this thing, although once I switch back to an x86_64 with more memory, better GPU and disk options, maybe this just feels like some kids toy.

Neko98 ARM!

I don’t know how I didn’t think of this, but I also ported Neko98! Although the STL is having an issue with the ‘control panel’ so Neko is on autopilot.

This app can’t run on your PC

As for the emulation, it is 32bit only, so expect to see this stupid message quite a bit. The neckbeard is a nice touch though.

Also built into the thing is a cell modem. I guess it’s really not a surprise as the 835 really is a cellphone SOC. I have a ‘wifi egg’ as they are called here, a WiFi hotspot with unlimited internet from CLS, which is on the old 4G network. I popped the SIM in, and it picked up the APN settings on it’s own and I was connected in under a minute. I have to say that it’s about time that SIM cards have this stuff programmed into them for a plug & play experience. And thankfully the ASUS is unlocked, although from what I understand these were sold in the USA bundled with some cell service plans.

For anyone with one of these rare machines that cares to play along you can find my built stuff on my ‘vpsland’ archive:

And the f2c/dungeon build along with the C/C++ compiler is in the aptly named dungeon-2.5.6-ARM(32bit) file.


(This is a guest post by Antoni Sawicki aka Tenox)

As I previously mentioned I’m slowly but surely uploading all my stuff to

You may want to know that I just finished uploading apps for Windows NT RISC… Alpha AXP, MIPS and PowerPC. Happy downloading.

ReBirth RB-338 v.2.0

I’m not a big sequencer as I’m just terrible when it comes to music. But apparently on Wikipedia Propellerhead had set the download free, although download links now are inoperable.

After a lot of googling around I found it split up on one of those annoying download sites. So I spent the night waiting for stupid timers, training an AI to sport automobiles & intersections (lol redlight camera training), and as a reward I got the download.

ReBirth on Qemu under Windows 95

I installed it on the floppy version of Windows 95 on Qemu where it needed IE 5.01, Direct X, Winsock 2 & Windows 95 SP1 updates (among others…) and yes it works!

Included in the downloads is some assists so you can run it on Windows 10 x64 if you are so inclined.

Also there is some MacOS X images, although I haven’t tested them. I need to drag my G5 into my office to try it, but it’s getting late, and I want to go home.

I put the download up over on You can download it here:

Early MSDN CD’s on

I ran across this, and thought it was cool. These CD’s are getting harder and harder to find, and unless you want the old physical disks, getting ISO images is, of course the next best thing.

Granted these disks replaced the much older Microsoft Programmer’s Library. The new CD’s use a Windows based search & interface program removing the clunky old MS-DOS program that made it feel like trying to view the world through a straw. (Although the up side of the MS-DOS version is that you could easily dump the video RAM and save the contents to plain text).

And in this brave new post Windows 3.0 centric world of Microsoft just about everything regarding OS/2 was dumped, and the seeding of Win32 via Windows NT had started.

Naturally after winning this war, Microsoft withdrew many low end products and just couldn’t compete with the tidalwave that was GNU/Linux.

At any rate for the curious kids down the road that want to see what all the fuss was with Win16, and how Windows 3.0 had changed the landscape removing the force of IBM it’s worth a look.

Adding DOSBox’s MPU401 to Qemu 0.90

I thought this may be something cool, if not kind of pointless. Anyways the MPU401 UART can be run like a traditional serial port with an IRQ, in intelligent mode, or just as a ‘dumb’ device you can just bit bang to talk to MIDI devices. So while playing with DOSBox I thought it’d be fun to take it’s emulation and plug it into Qemu.

And this is the end result.

It’s far from perfect, when it works it does tend to work well, although it fails to work with things like Return to Zork, but it does work with DMX’s sound code in DooM and the MPU401 driver for Windows 3.1

While doing this I was originally struggling with mapping the IO ports. Qemu has some functions to map in the memory model to assign a function that will trap read/write space. In this case base is 0x330 the base of the MPU401 device.

register_ioport_write(base, 8, 1, mpu401_ioport_write, s); register_ioport_read(base, 8, 1, mpu401_ioport_read, s);

I was thinking that the port 0x331 needed to be mapped in the same way, but it turns out after looking through more of the source, it’s actually a word aligned access. So in that case you can use a switch to see which port is actually being accessed.

static uint32_t mpu401_ioport_read(void *opaque, uint32_t addr) { switch(addr&0xf) { case 0: return(MPU401_ReadData(addr,0)); break; case 1: return(MPU401_ReadStatus(addr,0)); break; default: return(0xff); break; } return(0xff); }

Pretty simple, right?

And from there it’s a matter of mapping the DOSBox MPU code, along with the Windows interface code. Since I’m not using intelligent or IRQ mode, I just amputated the code where applicable.

If anyone wants to look at what I did to merge into anything else (and probably do a better job!) it’s on sourceforge as mpu401.c.

Otherwise the binary is available on sourceforge:
