I spent some time today refactoring the difficulty levels in Razing Core.
If the difficulty range is too great it can damage the flow of a stage at certain levels. I know how I want the game to feel but I also want to provide enough difficulty options.

This feature was late for the Razing Core demo but I've now added more background destruction for scoring, and it's just fun to destroy things! #mastersystem #homebrew

I'm currently developing games for the SEGA Master System. I like to use pastel or dark backgrounds with bright and bold foreground sprites.

Dev update: the game is around 60% complete and should be released in the next 6 months.
Following the addition of destructible items I'm also thinking about adding a 3 minute caravan/score attack stage, but we'll see closer to the end.

The SMS only has two true grey colours but you can use a neat trick.
Here I use a midtone brown, which when placed alongside other bright reds appears grey.
Also notice dark grey appears green when placed in red, as green is opposite to red on the RYB colour wheel.

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.

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.
