reassembler68k has been hard at work porting Sonic the Hedgehog to the Amiga and posting videos of his progress. It's hard work! So many tricks! Anyhow, there is a one-level demo to try in your favorite emulator or on a real A1200.

I always wanted one, but they were out of reach. My 15C was neat, but I lusted for a 16C. I accepted the Casio CM-100 "Computer Math" as a compromise. It's a little hard to find but a lot cheaper. It has very good bitwise functions, and I love this era of Casio design.

This is so good. Utterly pragmatic about the pros and cons of using Linux over Windows, and how much it will realistically cost you. And notice I'm not saying switching. This is not Linux evangelism. This is a way to get through a bad period of Windows history that you won't completely escape.

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?

The layout engine is working great. Those little frames around the debug modules? That used to be a terrible hack. Each module is an independent text console but their frames were drawn separately on a giant console in the background. Now each console draws its own frame in an all new terrible way.

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.

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.

Years ago, before Cintiq, I had a tiny Wacom and I don't think I managed to do a single productive thing with it. Today's tools seem like true force multipliers. Six months ago I nearly bought a hybrid laptop-tablet with a stylus. Instead, I went with something less expensive with good battery life. Though I have twinges of regret, the truth is I haven't drawn seriously for 25+ years. I should probably stick to paper until I feel like the passion is back.
