Kobo II Tech Preview 1 released!

SDL Development
1

I’ve been a bit hesitant to post here about this, as it’s a proprietary and
(so far) closed source project, and as such, of limited interest to other
developers. It does use SDL - but so do a lot of commercial games.

However, there is a playable tech demo now, so… :slight_smile:

The Kobo II Tech Preview is now available for download!
Long overdue release ? short announcement! ;-)

The 32 bit Windows build can be found on the official
site:

Direct download:

From the included README:

Kobo II Tech Preview 1 Release Note===================================

Kobo II (working title) is a top-down scrolling 2D
shooter, developed completely as a one-man endeavor
by the creator of Kobo Deluxe.

Unlike Kobo Deluxe, Kobo II is physics based, and is
intended to be played with dual analog sticks. (As in,
a modern game pad.) Although aiming to be a bit more
accessible and less unforgiving and frustrating than
Kobo Deluxe, Kobo II is in no way intended to become
a low resistance casual shooter.

As you may know, Kobo Deluxe is not an original game,
but rather a new engine and new media for the game
logic from Akira Higuchi?s XKobo. As such, Kobo II is
actually a new game by a different designer, more
than a true sequel.

It may in fact turn into something rather different
over time ? and this is where You come in, aspiring
fighter pilot! This game is for You, me and all others
who loved XKobo/Kobo Deluxe, and want to see that
concept upgraded to modern standards. I want Your
ideas and feedback, to iteratively develop Kobo II to
its fullest potential.

Downloaded and unzipped with 7-Zip, and my anti-virus is Windows Defender,
and there were no issues. Nice menus, by the way :)On Thu, Dec 8, 2011 at 8:38 PM, JeZ-l-Lee wrote:

I download the Kobo 2 Tech Preview 1 compressed file for Windows® from
your site.

BUT, when I tried to extract the ZIP my antivirus software told me its
malware???
(I use Avira antivirus.)

I got a similar false positive from AddAware, when cross-compiling with a
different GCC version and statically linking everything. These applications
have a dumb trigger on some certain network API call, or what gives…?

Also, I’m using UPX, but that’s used on all of the binaries, so that’s not
likely the problem.On Friday 09 December 2011, at 02.38.12, “JeZ-l-Lee” wrote:

Interesting… It would be less surprising if something triggered on one of
the VMs in kobo2.exe, as VMs can be used for hiding malicious code in a less
obvious form than native code.

Probably just some random byte sequence in SDL_net.dll that matches something
in the database.On Friday 09 December 2011, at 06.12.15, “JeZ-l-Lee” wrote:

Hi,

Just to be scientific, I downloaded SDL_net.dll to my desktop
and ran an Avira virus scan on the single file:

It passed… Not sure why its considered “malware” when its in your game
demo…

It is a quite common warning for binaries compiled with mingw.

Somehow there is a byte sequence there that triggers these warnings.On Fri, Dec 9, 2011 at 8:45 AM, David Olofson wrote:
