@Fourus I use "DejaVu Sans Condensed".

I'm having the same problem as the person below me. What font did you use to fix the problem tototoro?

I installed vasm from AUR and xcftools from community repo. Do I need to install some fonts?

EDIT:

I changed default font in KDE Settings and it works now. I don't now why it didn't work with Nimbus Sans.

The multiple defined errors is due to the code not being GCC 10 compliant, since it defaults to -fno-common now. https://gcc.gnu.org/gcc-10/porting_to.html

That error can be solved by changing the comparison in mw_putc function to this:

static void mw_putc(megawifi *mw, uint8_t v)
{
    if (mw->receive_bytes >= sizeof(mw->receive_buffer)) {
        return;
    }
    mw->receive_buffer[mw->receive_bytes++] = v;
}

But it still fails to build, with a lot symbols multiply defined.

Fails to build for me :(

Blastem segfaults if it can't find the images/ directory. This seems to be new to 0.6.2. The offending line of code is in nuklear_ui/blastem_nuklear.c 1382. With no images to load, controller_image is nothing so a division by zero occurs.

AFAIK, the optional dependencies are only required for the menu.bin ROM. I do not get any segfaults when entering the controllers menu. But I have no gamepads plugged to my computer, so the menu only has the "Back" button.

I get a segfault when selecting the "controllers" menu option. The program author thinks it may be a packaging issue. For more, see http://www.sega-16.com/forum/showthread.php?34009-BlastEm-0-6-1-Released&p=840166&viewfull=1#post840166

Also, I'm confused about the vasm and xcftools optional dependencies. Are they only for generating the menu.bin ROM, or are they also needed for the Nuklear UI?

Thanks!

Stable version 0.6.2 is out!

Version 0.6.1-1 fails to pass the validity check.

It should work now. I set permissions to the "games" group so if you're not already part of it, you should add yourself.

Plus, it doesn't run out-of-the-box due to permission errors (crashes when trying to run a binary): width: 640, height: 480 Window created with size: 640 x 480 Failed to open shader file default.v.glsl for reading Failed to open shader file default.f.glsl for reading $ ls /opt/blastem/ -la total 448 drwxr-xr-x 1 root root 102 Aug 1 15:15 . drwxr-xr-x 1 root root 112 Aug 1 15:15 .. -rwxr-xr-x 1 root root 387296 Aug 1 15:15 blastem -rw-rw-rw- 1 root root 4479 Aug 1 15:15 default.cfg -rw-rw-rw- 1 root root 47031 Aug 1 15:15 gamecontrollerdb.txt -rw-rw-rw- 1 root root 11689 Aug 1 15:15 rom.db drw-r--r-- 1 root root 56 Aug 1 15:15 shaders $ ls /opt/blastem/shaders/ -la ls: cannot access '/opt/blastem/shaders/.': Permission denied ls: cannot access '/opt/blastem/shaders/..': Permission denied ls: cannot access '/opt/blastem/shaders/default.f.glsl': Permission denied ls: cannot access '/opt/blastem/shaders/default.v.glsl': Permission denied Giving +x to the shaders directory fixed it for me.

Consider adding the 'megadrive' keyword, so the package can be found when searching for 'megadrive' instead of just 'mega drive'.

It builds perfect now, including the menu option. Thanks!

It should be fixed now. I forgot it needed xcftools, also from AUR.
