Every time I finish making a stage in Razing Core I replay the whole game up to the end of that stage.
I can honestly say this is the most fun I've had playtesting one of my own games so far. I hope everyone else will feel the same.

March 2025 marks the launch of Homebrew Factory, with NES support for developers.
This was followed by Game Boy/Color in June, then Mega Drive/Genesis last December.
2026 promises to be just as exciting, with more consoles coming to our platform ☺️

In Razing Core there's a small period of invincibility when you collect anything, this allows you to be more aggressive or escape to safety. #homebrew #mastersystem

In 2025 I released two new SEGA Master System games and started work on another.
In 2026 my goal is to release another two for SMS and another unknown project.
Thanks for all your support this year!

As amazing as the technology is for these replacement parts (I also have a region switch on my SMS), the heavily upgraded Game Gear begins to resemble the Ship of Theseus (or Trigger's broom if you're in the UK). At which point you have to ask if it's still a Game Gear.
I gave this Game Gear an overdue upgrade. USB-C rechargeable batteries, clean audio board with stereo support, new shell, IPS screen, and HDMI output.

A nice SEGA Mark III reproduction of Astro Climber. The title font was changed but the main artwork from the manual looks really nice on the cover. 😎 #mastersystem #homebrew

"It takes a lot of hard work to make something simple."
I've spent the last week optimising enemies to free up more CPU time. It's improved significantly since the demo.
This will be a constant cycle of building and optimising right to the end.

I'm still working hard on Razing Core most nights, but nothing new I want to reveal yet.
The game play is beginning to feel connected rather than a series of disconnected challenges.
