If you just want to race your Mario Kart Live cars around with your kid at full speed, did you know you can use a Steamdeck and skip a lot of BS?

PhotoCraft did better than I expected, but in the 309 test files it created BAD SAVES that can't be opened by photoshop in 42 of them, so beware

Big thanks to Eduardo ( @martiano ) for giving a micro-talk on his Try Omarchy project at our rl monthly meetup in Kyoto last night. but also... sharing that he's played Growtopia since he was 11 and some various uh, technical tricks he did with it

Trying to put my (literal) finger on why Wolverine's controls feel so mushy. I think part of it is it can randomly take up to a SECOND to actually run after pushing the run button!

update: in battle it' s fine, my complaint stands but I guess there are kind of two modes, depending on the area/activity

Very early engine test of a new game I'm working on! By the way, did you know the best thing about being indie is being able to put yourself (and actual building) into the game? I mean, they say to make what you know... (unnamed, but will be psychological horror)

Astra's visual understanding is next level. bought four dog lights and THREE already have broken clasps. From images (and a few measurements) it was able to create a working 3d printable replacement

I'm steaming now! Help me test out gamebot, an all local AI that tries to beat infocom games. (it listens to chat for help, I'm sure that won't turn out badly) twitch.tv/rtsoft Planning to leave it on a few days

er, *streaming, rather. Ok, I've tried DeepSeek-V4-Flash-Vision-Exp, Qwen3.8-Flash-Next and GLM-5.3-Flash and we're still 0/25 on winning an infocom game. Ending the experiment, will try again when local LLMs improve a bit more...

3ds support (using a modified Azahar) coming to HoloVCS's github soon! (runs on Looking Glass 'holographic' displays) - I've introduced a new "mode 2" especially for this, it's pixel accurate, works much better than the 'diorama' method I used for virtual boy/nes

Playing Zelda on a $99 Looking Glass Go 'holographic' display. Big thanks to @LKGGlass for open sourcing their Unreal plugin - got it updated for Unreal 5.8 and hyper optimized for my project. (100x faster quilt rendering!) github.com/SethRobinson/Holo…
