My Adventures in gsLib – part 2

May 14, 2008

With the valuable help of Lukasz I’ve fixed the old gsLib0.51 sources as from ps2dev.org to build under the current ps2sdk and I hosted it here :

gslib_0.51_ps2sdk_cleaned
gslib_0.51_ps2sdk_…
Hosted by eSnips

and also here :
gslib_0.51_ps2sdk.rar

Once again, thanks Lukasz!

Update :
The lib was added to the official ps2sdk subversion repository at
svn://svn.ps2dev.org/ps2/trunk/gslib

My Adventures in gsLib

May 6, 2008

I’m starting to explore the old graphic library gsLib. But why, since gsKit is the standard nowadays, have a superiour performance and gsLib is no longer updated? Simply because gsLib, unlike gsKit, supports low resolution screen modes! Gosh, I hate interlaced modes in PAL CTR TV’s and that’s the only mode gsKit uses. In order to use a non interlaced, you have to modify to gsKit source to set, for example, a 640×256 or 640×224 screen mode. Personally I failed to add a pure low resolution screen mode like 320×256 to gsKit (I’ll try again someday) so then the interest in other graphic libs.

Another bonus feature the gsLib adds is mentioned at its documentation:

How cool is that?

This allows us to hook a function to the vsync video signal, so the function will run at the vertical refresh rate! This allows to compensate for the lack of easy to setup interrupt support/multitasking on the PS2 using the free ps2sdk.

The drawback of gsLib it that its written in C++, so the projects that uses it must be also in C++ … Oh well, nothing is perfect.
