Everyone at Romero Games is deeply saddened to learn of the passing of Bobby Prince. He left an incredible mark on games and on my life.

I fixed the Commodore Callback. Now we're willing to spend $500 for 25-50 year old technology. Show us all the ways it integrates with the C64U.

Identity crisis #5!!! My #picotron twin-well #tetris game now has a Metroid theme (it's what I'd originally planned - hence the wall crawlers - but in a completely different way) and a new name, "Tetroids" Testing level palettes and using the whole screen. #gamedev #retrogaming

Title: Black Castle 2 Dev: @User0x7f Link: user0x7f.itch.io/black-castl… Yooooo, this game is responsive and fun, and spamming that attack button never gets old. If you get a chance, check it out. I promise you will get some enjoyment from this one. I feel like the N64/GB/GBC era is alive and well.

CHRONO RUNNER for MSX (by MSX Italia Association) Well designed puzzle platformer where the player gets crystals that are able to rewind time, but should be used with careful planning. Part of MSXdev25: msxdev.org/2026/03/14/msxdev… #MSX #gamedev

A moment of recognition to all you solo indie game devs silently grinding it out. Sacrificing fun and socializing in pursuit of a dream and a goal. Worrying if it's good enough. Sweating the small stuff. One night at a time. Respect. You'll get there. #gamedev #IndieGameDev
