Refactoring every bus-connected component in my emulator surely won't break anything.

This new Apple II game is an incredible take on Frogger and Crossy Road. It's extremely well-made and has varied and fun challenges. Bravo, Ben and Paul Wasson.

I finally got smart and quit writing weird formulas to get my composite color decoding to look right. Now I can load raw images into Affinity Photo, tweak the colors until I like them, and use those tweaks to create a LUT texture for a new color correction shader. Why did that take me so long?

What a great hack!

The Advent of Compiler Optimizations has wrapped, and what a fascinating series it was. If you're a coder and you missed it, check it out and learn what absolute folly it is to try to outsmart the compiler.

I finally made some progress with a layout engine for my emulator's debugger. The manual layout I've been using (right) is a nightmare to manage and essentially impossible to change at runtime. The new system (left) easily handles dynamic element insertion, deletion, resizing, and container fitting.

The PIXELFALLS browser-based game engine looks pretty neat! It's reminiscent of the PICO-8 retro "fantasy console". Edit sprites, levels, Lua code, and music all in one place. Play and share your games in the browser. Limited early access.

Added a fun memory heatmap to my Apple II emulator. The black area represents the 64K address space. It shows memory accesses in real time, blue for reads and red for writes. It still needs some work, but the proof of concept works. Ultimately, it should show all memory, not just the address space.

How accurate is the Analogue3D really? Kaze points out many problems but there is hope they will be fixed. It's not a bad product, it's just not yet the one they are advertising.

This explanation of the SHA3 message digest algorithm is remarkably clear. It seems complicated at first yet it's elegantly handled by embarrassingly parallel bitwise operations. I don't know who might find this as interesting as me, but here it is if you do […]

This is a lovely biography of Roe Adams III by Hiromasa Iwasaki. Little has been written about Roe, and while his credits are short, they include both foundational CRPG pillars, Ultima and Wizardry, which is incredible. Read how he revitalized a stagnant genre […]

Thomas Cherryhomes is on a roll. He recently started posting information about The FROB, an Atari 2600 debugger that used the Apple II as a host. Now two community members have managed to reverse-engineer the hardware, and another has it running in MAME.
