Change of product direction, good and bad news!

This is frustrating news, and must be more so for the team that has invested so much in getting it to this point. <br /> <br /> I’ve been developing a game for this system since the emulator was first available. With this news, I think I will be pausing development until a real system becomes avail...

New demo uploaded: Wolfenstein 3D - raycasting demo with textures

You have per height routines, but could you also have a per texture+height routine? You could take advantage of textures created with vertical runs of identical pixels to reduce “reads” from the texture. I’d imagine the answer is that that would use a ton of memory, but I’m wondering how much memory...

Commander X16 vs. Mega 65

Random, disjointed thoughts... I like the simplicity of the X16 as a platform for learning and exploring assembly programming. All those boot menu options etc on the mega65 just put me off. Also the case is ugly - ew. I don't care about backwards compatibility either - it never works on the one thi...

More exposed keyboard interface


Bumping this with a related query...

Does the keyboard scanning work in the same way as the C64? If I wanted to write my own keyboard scanning routine, would it have the same rollover issues as the C64?.. or does the X16 ROM do things its own special way?

CPU meter

The code is a horrible, unpresentable mishmash of magic numbers and macros, but I'll do my best... This is the main wait loop which just thrashes and waits for the vbl interrupt to set a flag <blockquote class="ipsQuote" data-ipsquote=""> <div class="ipsQuote_citation"> Quote </div> <div class="ips...

CPU meter

Been tinkering away at my game, and thought I'd spend some time adding better debug tools, so I added a CPU meter. I was getting concerned that I had no idea if my plans were going to fit into my frame budget. The screenshot shows I'm using 32% of the CPU resources available. Well worth adding beca...
