Re: Drawing with correct aspect ratio

OK, I will do that later. For now I rounded up a general article on the matter on my site: http://www.jubatian.com/articles/using-non-square-pixel-aspect-ratios-in-gimp/ What do you think about this? Transforming to be more Uzebox-specific of course for the Uzebox wiki. It might take some days thoug...

Re: Tank Fu

Nice old-school game! It feels quite entertaining, controls are responsive even in the emulator, graphics is fine for the purpose. The AI may need some polish though for the single player game, something what even I can beat in one sitting doesn't cut :) Of course the best of this game should be mul...

Re: Drawing with correct aspect ratio

Eh, I found it can be done in Gimp itself, a whole lot easier! An example of drawing for 7 cycles per pixel is here (uploaded on imgur) , Gimp properly scaling the 1,5:1 aspect ratio. Great! I also plan on creating stuff for the BitBox console keeping portability in mind, using a 360x360 3:2 display...

Re: Embedded Electronics

Huh... Here whenever I decide to look around to check who is hiring, I almost always see open positions at just about every larger firm dealing with anything safety critical, and these things won't just vanish in a puff of smoke. Maybe especially because mobile is the trend today, people are not tha...

Re: Embedded Electronics

I think embedded is in quite big demand, although those who seek for such developers also have steep requirements, and you won't necessarily find the job too much amusing. These micros are used all around in more or less safety critical equipment, household stuff such as simple washing machines, the...

Re: Raycaster Experiment

Nice and quite responsive! I also found a bug in the emulator by this, hiding away since my original instruction set reordering. Stupid elusive little thing, took a half hour to locate the commit, then another hour to figure it out... A pull request is up with the fix, then the current emulator will...

Re: Tempest is possible

Wouldn't it be simpler to just use "-x assembler-with-cpp" for every assembler source? The kernel already relies on that, and so this would more likely eliminate further problems: do it consistently and don't bother with using ".S" for a few files while the rest uses ".s&quo...

Re: Palettization - color; colour; couleur; färg; farbe...

Pretty interesting, I need to better understand that MULS trick! Sign extending. It treats the color index input as a signed value, so in the multiplication it uses it as 0x0000 - 0x007F when its bit 7 is clear, and 0xFF80 - 0xFFFF when its bit 7 is set (bit 7 being the sign). Or just play it out n...

Re: Mode 74 development

Scrap the SD card... I think I just made a breakthrough in compression! :D Remember the C64's Multicolor mode? What I completed (not tested yet, just meticulously laid out instructions, counted cycles and jump ranges) is basically that, a Multicolor style framebuffer where a 8x8 tile takes only 18 b...

Re: Palettization - color; colour; couleur; färg; farbe...

Sorry for tripling, just this might be interesting. Based on the nops scattered around in the RAM tile part of the above scanline loop, I thought I will try something. That is, to cram in another MUL on the RAM tile part to allow for the "normal" blocky RAM tile layout. It looks like this ...
