Announcing DJGPP 2.05 Beta 1

Yes, you read that right, not only is DJGPP still alive, but after the much stalled 2.04 beta cycle that has been going on for more than a decade, they have decided to push forward with 2.05 to get a release out there!


This is announcement of DJGPP 2.05 beta 1

It has numerous changes since previous DJGPP 2.04 beta 1 release in 2003.
Unfortunately DJGPP v2.04 was never released and old beta version slowly
became almost unusable together with other newer DJGPP packages.

More information about changes in DJGPP 2.05 beta 1 is available at

both in sections about changes in 2.04 and 2.05. The same information is also
available in file info/kb.inf in

It needs a lot of testing. Please test it if you have time and/or are
interested in any of the above features. Any level of testing would be

The beta is not available via the Zip Picker interface. You can download it
from here:

Additionally RPM packages (source and binary packages for i686 and x86_64) are
available from

Please see the README file for instructions on how to install the beta:

You can also download DJGPP 2.05 beta 1 packages from DJGPP mirror sites:

Thanks for all who have contributed to development of DJGPP

I haven’t used it yet, but I see the following files in the beta directory:

djdev205 DJGPP V2 Development Kit and Runtime
djlsr205 DJGPP V2 Base Library Sources
djtst205 DJGPP V2 Test Programs (for testing the C library)
djcrx205 DJGPP V2 Cross-to-DOS Compiler Support Files (from djlsr/djdev)
djtzn205 DJGPP V2 Timezone Files
djtzs205 DJGPP V2 Timezone Sources

also floating around in the beta directory is GCC 5.1.0!

No doubt it’ll be a good excuse to rebuild and update some Quake related things to see how we fare in 21 century MS-DOS!

Shadowrun Hong Kong!

I just saw this pop up on Steam, Shadowrun Hong Kong!



I was hoping this is available right now, but it’s slated for ‘summer’ which is soon!

$19.95 USD

With any luck, later on it’ll come to Android too.

shadowrun FASA 7100Anyways for those of you who don’t know Shadowrun started life as a FASA based tabletop game, then made the transition later to a video game for the SNES, and Genesis.

Shadowrun is set in a dystopian cyberpunk future that blends magic and dragons as well.  It’s very similar to Palladium’s RIFTS which introduced a world with technology and magic, although it wasn’t as focused on the new and exciting genre of cyberpunk.

Those who loved the top down game, were later saddened with FASA’s demise.  Microsoft picked up the property and in 2007 released their own spin on the game.  It was not well received.  In a nice twist of fate, the game was re-licensed to the original developers who release Shadowrun games to this day.

.And yes, while I’m on the gratuitous Hong Kong action there is always Sleeping Dogs.



Besides that, what else is there?

Mahjong, I guess.

MAME to go open source!

As I write this I don’t see anything outside of this twitter tweet (post?), along with this Gamasutra post.

The only ‘good’ part I see in there:

Milanovic tells Gamasutra. “Our aim is to help legal license owners in distributing their games based on MAME platform, and to make MAME become a learning tool for developers working on development boards.”

So I guess they want to do android and embedded Linux stuff?

Does anyone know anything more concrete?

It does sound exciting, especially for MAME’s chipset emulation which, let’s face it is superior, and being able to plug them into other emulators that are ‘good enough’ or even different purpose than full system emulation is a good thing.

Also from other sources, I hear that MAME/MESS are to be fully merged, and will be shipped simply as a single executable called MAME.


Well I should have checked the source.  Many things are going to a ,BSD-3-Clause license for example the MUSASHI 68000 processor emulation:

// license:BSD-3-Clause
// copyright-holders:Karl Stenerud
/* ======================================================================== */
/* ========================= LICENSING & COPYRIGHT ======================== */
/* ======================================================================== */

While others are going LGPL, or GPL.

Building SDL2 for Android

Phew is this rather involved.  First you need to download over a gigabytes worth of files. For something that is going to be embedded you need a MASSIVE amount of space.

You need:

I went ahead and installed the JDK in a normal directory,  The same went for the Android SDK.  The NDK is a 7zip file, that I went ahead and put at the root of my C drive because I’m that kind of guy.  Next I unpacked ant into the NDK directory, and SDL.  For SDL be sure to use some command line or other unzip tool that makes sure that the text files are translated appropriately, otherwise they are impossible to read in good editing tools, like notepad.

cd C:\android-ndk-r10d\
unzip -aa \Downloads\
unzip \Downloads\

Now to stage the project directory.  The ‘Android project’ that we are going to build out of is *INSIDE* the SDL archive.  And SDL needs to be inside the project directory, so we xcopy out the bits we need.

md proj
cd proj
xcopy ..\SDL2-2.0.3\android-project\*.* . /e/s
md jni\sdl
xcopy ..\SDL2-2.0.3\*.* jni\sdl /e/s

Now we need to set some environment variables.  Again this is where my stuff is, yours may be different.

set NDK_ROOT=C:\android-ndk-r10d
set ANDROID_HOME=”C:\Program Files (x86)\Android\android-sdk\”
set PATH=%NDK_ROOT%\apache-ant-1.9.4\bin;”C:\Program Files\Java\jdk1.7.0_79\bin”;%ANDROID_HOME%\tools;%ANDROID_HOME%\platform-tools;%PATH%

Now we need to edit the jni\src\ and point it to your sources.  In this case I’m using‘s simple main.c &  image.bmp as I haven’t written anything exciting yet. Change YourSourceHere.c, to main.c

Now copy in the image.bmp file into the assets directory:

md assets
copy image.bmp assets

Now we can fire up the native compiler tools, and by default it’ll compile for ARM thumb, ARM v7a, and x86


Now for the java.  Android is a java platform, so now we have to compile the wrapper that calls our C/C++ code.  First we have to set what version of Android we are compiling for:

android update project –path . –subprojects -t 12

And now we compile with ‘ant’ by typing in:

ant debug

And if all goes well you’ll get:

Total time: 2 seconds

Now to run the program, we can fire up one of the emulators (you will have to configure one no doubt) using AVD.  I just clicked around, and picked something that’d launch.  The shell seems to crash a lot, but otherwise yeah.

Now to upload our application to the emulator once it is running:

ant debug install

And if all goes well, you’ll see:

[echo] Installing C:\android-ndk-r10d\proj\bin\SDLActivity-debug.apk onto d
efault emulator or device…
[exec] pkg: /data/local/tmp/SDLActivity-debug.apk
[exec] Success
[exec] rm failed for -f, Read-only file system
[exec] 1985 KB/s (1028625 bytes in 0.506s)

Total time: 5 seconds

And on my first shot at running, it crashed.

Unfortunately SDL App has stopped

Unfortunately SDL App has stopped

Using ‘adb logcat’ on the emulator I was able to find this line:

java.lang.UnsatisfiedLinkError: dlopen failed: cannot locate symbol “signal” referenced by “”…

Well it turns out signal was an inline function until platform android-21, now it’s not inline anymore. When you use the ndk r10, android-21 is used by default but it’s not fully retro-compatible with devices running former Android versions. In this case, signal can’t be found on the emulator. (It did run properly on my Lollipop phone).

Fixing this is simple just edit jni\ and add in the APP_PLATFORM line:

# Uncomment this if you’re using STL in your project
# See CPLUSPLUS-SUPPORT.html in the NDK documentation for more information
# APP_STL := stlport_static
APP_PLATFORM := android-12
APP_ABI := armeabi armeabi-v7a x86

Re-compile with ndk-build, and re-upload with ant then you are good to go.



I grabbed, and borrowed some phones around the office, including an x86 phone and yeah it works!

SDL2 test!

SDL2 test!

I haven’t even tried to cross build libraries on Windows… I suspect I should be doing this on OS X or Linux.

All aboard the VENOM hype train!

So here we go, another time for another major security threat, and this time it’s the “VIRTUALIZED ENVIRONMENT NEGLECTED OPERATIONS MANIPULATION” aka VENOM attack.  Yes it has a website, and even a logo! (Creative Commons Attribution-ShareAlike 4.0 International License)

Look at me!

Look at me!

So what is all the fuss about?  Well if you can compromise a Xen, or KVM (and QEMU) VM to run code that bangs against the floppy controller it can have a buffer overflow exploit.


But, I know what you are thinking, most people who KVM use guest OSs that either don’t have floppy drivers, or even explicitly disable the floppy controller.  And from the site:

an unrelated bug causes the vulnerable FDC code to remain active and exploitable by attackers.


But let’s calm down, first the attacker has to get root level on the VM before they can think about doing anything.  Of course this is a BIG problem for VM resellers.  Hopefully the patches will be available quickly, and they will be moderately disruptive, especially for those of us who still use virtual floppies.

The source patch has been released on the Qemu mailing list right here.

Overheating boxes…

So apparently sometimes doing ‘stupid things(tm)’ can overheat your disks, and your box… So you should always keep an eye on the temperature.

So for my benefit more so in the future, and maybe others, here is a quick script to check the temperature of the processors, disk, and any changes in /var/log/messages to see what is going on.  I guess I should make it more modular, and not hardcode stuff, but here we are.

# Read the disk temperature

disk="smartctl -d ata -A /dev/sda  | grep Temperature_Celsius | awk '{print \$10}'"
diskt=$(eval $disk)

if [ "$diskt"  -gt 40 ];
	error=$"Disk temperature is hotter than 40c it's now $diskt\n"
#	error=$"Disk temperature is fine, it's $diskt\n"

sensors| grep Core|awk '{print $3}'>/tmp/dat.txt


while read line
number="echo $line |sed 's/\.\0\°C//g'|sed 's/\+//g'"
cpu=$(eval $number)
if [ "$cpu" -gt 82 ];
	error=$"$error\nCPU core $j temperature is $cpu"
	#error=$"$error\nCPU core $j temperature is $cpu"
done < /tmp/dat.txt rm -f /tmp/dat.txt if [[ -f /tmp/messages.1 ]]; 	then 	tail /var/log/messages > /tmp/messages.2
	dstring="diff /tmp/messages.1 /tmp/messages.2" 
	logadd=$(eval $dstring)
	if [ ! -z "$logadd" ];
	mv /tmp/messages.2 /tmp/messages.1
	tail /var/log/messages > /tmp/messages.1

if [ ! -z "$error" ];
	echo "there are issues.."
	echo -e $error > /tmp/message.tmp
	mail -s "errors on machine_name" 

Of course, it can and should be expanded to check up on things like SMART disk errors, and other things going on.  And of course in the crontab, something like:

*/5  *    *   *   *   /root/

To run it every five minutes.  As always it’s lacking comments, full pathing to executables, and much of anything to keep it safe.  I’m sure if I was smart I could read more from pipes and variables, but I’m old so I read from files.  If you were looking for the bash shell script expert, it’s not me. lol

Going away for a bit

So Cloudflare is hitting my site like crazy, basically DOS’ing me.  So Im going back to the old way.  And then as luck has it my DNS guy has a fit once, I move the root enteries off Cloudflare.




Yeah, so looks like I’m going off line, but once I get the DNS sorted out I’ll be back.

OK I’m back.  Turns out it’s someone in Hungary that has their client misconfigured. – – [11/May/2015:11:21:17 -0400] “GET /?feed=rss HTTP/1.1” 301 496 “-” “Mozilla/6.0 (compatible; Firefox 9.0; Windows NT 5.1; SV1)” – – [11/May/2015:11:21:18 -0400] “GET /feed/ HTTP/1.1” 200 37325 “-” “Mozilla/6.0 (compatible; Firefox 9.0; Windows NT 5.1; SV1)” – – [11/May/2015:11:21:20 -0400] “GET /?feed=rss HTTP/1.1” 301 496 “-” “Mozilla/6.0 (compatible; Firefox 9.0; Windows NT 5.1; SV1)” – – [11/May/2015:11:21:21 -0400] “GET /feed/ HTTP/1.1” 200 37325 “-” “Mozilla/6.0 (compatible; Firefox 9.0; Windows NT 5.1; SV1)”

Scripted Amiga updated to version 0.82

It’s really amazing to see this in action, and knowing it’s all in javascript of all things.  The Scripted Amiga Emulator now in version 0.83 fixes sound on Chrome, bringing back that Amiga experience with next to no pain.  By default it’ll boot up AROS and various demos or game demos, but you can substitute it with any 68000 compatible kickstart ROMs, and whatever diskettes you have lying about.

Even better the source code is up on github, and now under the GNU General Public License v2.0.

Click here, and give it a shot!  Any modern browser with good javascript support is all you need to get going!

It’s short, but an interesting read none the less.
