vladikcomper on the SGDK discord has created an amazing and ridiculous mod for Sonic the Hedgehog (MD) in which quality degrades to different resolutions/numbers of colors unless you fill your blast processing meter up. It works real time in wide screen in a smaller rom size than the original game.

Gradius covers are something special 🤩
The artwork of #Gradius Gaiden by Yoshihiro Hashizume used on the cover of the Japanese #PlayStation release. Just a small upscale with a slight retouch since the original source was already pretty good. A big thanks to @ovga.bsky.social and the owner for sharing this piece!

"liberals struggle with the overwhelming volume of questions to be asked, answers to be offered... A fascist just has to be a storyteller. Because for fascists words do not attach to meanings, the stories don’t need... to accord with external reality."

What Does It Mean That Donald Trump Is a Fascist?
Trump takes the tools of dictators and adapts them for the Internet. We should expect him to try to cling to power until death, and create a cult of January 6th martyrs.

I have refrained from being political on social media, but I just don't care anymore. Last night was a disaster for our republic.

Above all else, the peaceful transfer of power was violated and America thought it wise to forgive that. I will not.

Polls don't vote!! Vote!👠🍊💥
A friendly reminder that we all thought the 2016 election would be a no-brainer. If you're registed, please, don't listen to the polls, don't assume - vote.

I don't think I was prepared for just how difficult VR is...aggressive FPS deadline, 2x images, very difficult platform (Android), software complexity due to things "built-in" image warping, etc. Ugh 😭

Time after time, I run into a bug that leaves me with a feeling that "this is going to be the one that does me in, the one I won't be able to solve"...and I figure it anyway. Doesn't matter how many times, I still live with this dread that I'll eventually hit the one that's too big for me lol
