Re: Mode 74 development

For the Mode 74 usage part, I will be around to help if questions arise. Maybe eventually that way could also evolve into a fitting tutorial. The most important techniques for the "usual" 4bpp tiled mode however can be already well observed in the sprite demo's source, and you may also che...

Re: Mode 74 development

I added it to the wiki. Tutorial... Eh. A bit hard getting myself to do something like. I already got into trying to design tilesets and other graphics for my planned game, already battling with space. Diverse world, many distinct areas, how to convey it in so little, what each of my tilesets should...

Re: Mode 74 development

I am thinking about creating some sane tutorial for this thing, to introduce it step by step so it could be understood in a reasonable manner. The Uzebox logo actually gave an idea: the mode can produce okay results with RAM tiles only which can be filled in easily from small tables. So for a start,...

Re: Inline Mixer - saving clocks

Just a bit of warning: It will also need a new set of seed values calculated since subtract with carry which the AVR has is not exactly the same as add with carry (even after complementing the immediate) which the original algorithm uses. But proper seeds should exist all right for this variant as w...

Re: Weber's Rants (tutorials)

I'm not sure I've come across Mode 74 on the wiki and forums before. Do you have a link? It is my experimental 4 bit per pixel video mode described on this board, here is the last page . You may check the sprite example (there is a binary attachment there) to see what it can do. Quite a complex mod...

Re: Emulator - get latest release here.

For my part I put Uzem kind of aside for now. I am happily using what I have for graphics mode development (with the timing printout hack I mentioned a few times which works very well in Linux using a console, allowing tracking problems in a video mode quite accurately). I just mentioned since the q...

Re: Weber's Rants (tutorials)

Maybe a custom video mode would be more realistic? Mode74, anyone? :roll: It can mostly do these, and the wide pixels should work OK with isometric (depends on the preferred view angle though, for Mode 74 you wouldn't get 2:1 like on the image here, but either 3:1 or 1,5:1). An important part it su...

Re: Inline Mixer - saving clocks

Quite a while ago I invented an interesting alternative to LFSR's for short sequences, you may look in that to see how it works out. Theory and algorithms are up on StackOverflow: http://stackoverflow.com/questions/17411712/finding-seeds-for-a-5-byte-prng (well, true not a very good "question&q...

Re: Mode 74 development

Blergh. I had some serious case of food poisoning to share my holiday with, only recovering now. Anyway, Mode 74 now received the capability of displaying the Uzebox logo proper, code (and examples) are up on GitHub: https://github.com/Jubatian/uzebox/tree/mode74 I did this in a manner so it interfe...

Re: Problems on the Games and Demos list

I think there is some way to specify frame delays for individual frames so you could have short pauses when the sentences display in Buddha for not extra cost (like me doubling the frames in my huge versions :roll: ) This is possible in Gimp. If you load a bunch of frames, and hit "Optimize fo...
