Hello!

Here's an emulator-compatible RAM-only version of RL. 16K or 24K expansion, still PAL-only.

By the way, I also have a blog nowadays, and I tend to write a lot about 8-bit stuff etc. Check http://viznut.livejournal.com/ or http://www.pelulamu.net/viznut/blog/

I remember realizing how SIN and COS work several years before they came up at school. However, I didn't realize that PI equals 180 degrees, but I did make some rotating triangles and stuff :)

I don't use emulators either and I only have a PAL machine.

By the way, the choice "I have both a real PAL system and a real NTSC system" is missing as well :)

Are you referring to PAL or NTSC with that 32? For PAL, the maximum number of logical characters per line is 35 (in the 6561-101 revision of the VIC chip, to be exact). POKE36864,0:POKE36866,161 - 33 columns without distortion POKE36864,0:POKE36866,162 - funny "sawtooth mode" POKE36864,0:P...

It does depend on the tv/monitor. One of the PAL TVs I've experimented with didn't even do 27 columns, while an old TV card with a VGA monitor did nearly 29. I'm still looking for a display device that would be able to show the complete horizontal scan (35.5 column-widths in PAL). That'd be helpful ...

I've never regarded PC as a superior gaming platform. Of course, Wolfenstein 3D had some never-seen-before graphics, but it was because of the raycasting algorithm, not the hardware platform. Several Wolf3D-like engines have been made for 8-bits as well. And besides, great numerical specs are never ...

Ok, I'll mention Brickshop here too :)

It's available at http://www.pelulamu.net/brickshop/.

I didn't publish it because it's still quite buggy, but you can give it a try. There's source code too!

PAL only, mainly because of the raster feature.

I would've slipped in a video bug that allows something like Flexible Line Distance (as in VIC-II). Of course, the bug wouldn't be discovered until the 2000s, but in any case it'd allow for some really wonderful raster effects :)

In case someone is interested, here's Brickshop: http://www.pelulamu.net/pwp/brickshop/ I was once thinking about the possibility of first doing a very chunky PC->Brickshop conversion for images and then finishing the pic on the real thing, but I then decided that it's be better to draw the picture ...

Some years ago I was taking my household trash out and I suddenly saw a C64 in the trashcan outside the building. I was even more shocked when I came back some hours later and saw a box containing ANOTHER C64 and several tape games for it. After some more searching I even found some tape drives and ...

It's nice to hear that you liked the demo! I've been planning on a new VIC demo that would show off some crazy new techniques and ideas that haven't been used yet. However, it's probably not going to be a sequel to the robot series (it's a bit too time-consuming to cleverly combine plot-driven stuff...

I'll be 30 in less than two weeks. That is, I was seven when I wrote my first Basic programs with my first VIC in December 1984. After a pause of over a decade, I came back to VIC coding in around 1998 when I was looking for a nice "extreme device" to write a demo for. I try to avoid exces...

Hello! It seems that people have been expecting me :) For starters, I'll perhaps need to explain the scanline renderer I used for some effects (such as the zoomer and the cubes in RL): You can alter the position and width of the screen area (in 4- and 8-pixel steps, respectively) via $9000 and $9002...
