Reposted by Mouse's Mistake (Niels Van Son)ateam @dreamcastforever.com · 21/09/2026(1/3) People have been asking me about this redesigned GDEMU clone (Dreamcast ODE). So I bit the bullet, bought one, and tested it. Firstly, all of the "faster speeds" stuff is pure marketing bullshit. Timing is handled by GDEMU firmware, and it's delicate. You don't want to arbitrarily increase. 3287

It's been a blast developing my little game "You Are Tomato" even though there were times where I thought about just giving up due to random lock-ups and crashes. I'm glad I didn't! Also, congrats to all remaining participants! #dreamcast 251

Reposted by Mouse's Mistake (Niels Van Son)Luke Benstead @kazade.bsky.social · 04/03/2026I'll never understand why people (including many engineers) can't see programming as the creative art that it is. LLMs generate code the same way they generate images or videos. Bland, mediocre, inelegant remixes of the training data. 161

That first 80% is way more fun, but that final 20 is soul destroying. It's essentially just looking at bugs going "ah, shit." #gamedev 3102
