Can somebody post example of smooth, endless vertical scrolling of plane (a or b) at 1px per frame?
I'm going crazy, can't pull it off.

Hi there!
It's probably overkill but the Propeller engine might be something of interest to you.

djcouchycouch, yep, overkill.
I want basic example, which you can port to your project or compile and quickly test on hardware.

False alarm.
Seems to be VSync problems, that's why I have tiny shutters.
Enable it in emulator - all ok. On TV it is also scrolls smooth.

Is there anything in particular that prevents sgdk from working properly on Linux or OSX if I swap out the gcc/ld binaries?
I'm guessing some of the tools are windows only, and I might need to tweak the makefiles, but other than that?

You will need gcc compiled for 68k development, some other tools and Makefile changes, etc. This is all already done for Linux, including SGDK here:

Oh, awesome, now I don't have to reboot to windows everytime I work on my game.
Thanks

Hi Stef, Thank a lot for the new version
In FONT.H line 19
#include "libres.h" --> Missing
The file should be auto generated by rescomp. Be sure to recompile the whole project. Maybe i made a mistake in the order of object file generation, i will check that

Good job!
Stef, It is possible to see GFX compression support example?

The "sprite" sample use it in a very transparent fashion. You basically just need to declare your image in resource file with compression parameter and that is done. Then you have all the tools.h file to handle manually decompression but if you use advanced method as VDP_drawImage(..) or VDP_drawImageEx(..) SGDK will handle it by itself (same for the new TileCache feature).

OK thank you, I've deleted the 'out' folder and I've compiled the whole project but the error appears again...

Well i don't have any problem here and the makefile looks ok. Can you post your compilation log ? the libres.h file should be generate automatically in the res folder.

But,... Do I need create a res folder into my project folder?

Oh it looks like you are using the wrong makefile :p
makefile.gen is supposed to compile your project while you need to use makelib.gen to recompile the library itself
