Several boxed copies of the Sega Master System homebrew game Frontier Force. The cover of the box shows a man with blonde hair holding a large weapon.

Work in progress next stage in Razing Core. Only 1/3 of the game is in outer space, so all the remaining stages will have a greater variety. #mastersystem #homebrew

I've been working on the Astro Climber manual today. It will be in colour with illustrations and will be easily printable.

I'm also working on providing translations in various languages.

I've tried to make it so that you can avoid each enemy in multiple ways, you can stun them, avoid, wait, or jump over for example. You just have to pick the right one in the chaos of the stage. #homebrew #mastersystem

Compression of the stage data has freed up over 2600 bytes! The priority will be to add a new enemy and some backgrounds. Sound and music is also being worked on. #homebrew #mastersystem
A screenshot of a program compilation output reads: "ZX7: Optimal LZ77/LZSS compression by Einar Saukas. File converted from 2816 to 157 bytes!"

You can now stun enemies with the grapple hook and I've added collapsing platforms too. #homebrew #mastersystem

Added the ability to grab on to the walls, so you can mistime it and fall off the stage that way too. #homebrew #mastersystem

I've added some small bits to this including stage loading and progression. It still needs enemies, pickups, and combat. #homebrew #mastersystem

A small demo I've been working on for Master System. This would be developed into a "budget title" type of game where you beat your high score. #homebrew #mastersystem
