Re: How to make space Spartans

So the questions is do you want to just recreate the game play or do you want to recreate the look/visuals. Could depend on trade-off between audio or video as well. With Mode 72, the VBlank is free to be utilized heavily for audio, such as even streaming from SD, to potentially enhance that aspect...

Re: How to make space Spartans

Video mode: I made some checks on this. The 3D area is 150 pixels wide (if I counted right), it seems to be that it should be 8 cycles / pixel (the usual 160 pixels wide mode of old microcomputers, 1x NTSC colorclock), vertically it is double-scanned. The closest match at the moment in my opinion is...

Re: Emulation and sync behaviour of a CRT monitor

Huh, thank you! I actually played a lot with tweaking VGA this way and that when I had a CRT, it is quite nice that they are analogue in nature, you can mess around with the signal to do interesting stuff with the display. Too bad the VGA had only two oscillators (the ~25.1MHz one for square pixels;...

Emulation and sync behaviour of a CRT monitor

Thoughts over how emulation may be improved regarding how it catches sync, what it may display when the signal is incorrect. CUzeBox currently mostly either draws a solid image or nothing at all. In some regards to try to remedy what Stephane (rv6502) mentioned, giving some difficulty designing vide...

Re: CUzeBox - The new official Uzebox emulator

I got a patch that doesn't seem to break the Uzebox games and works with my somewhat-degenerate signal generator... Sorry, but this isn't quite functional. It breaks the emulator's capability to correctly follow VSync, so you no longer see whether that part of the video signal is correct. The side ...

Re: 80 column text mode at quite high resolution

I'm being somewhat loose with the vsync signal and the emulator has a very narrow tolerance. Analogue hardware only cares if past a certain threshold of sync time with a simple capacitor charge/discharge and digital hardware only cares if it's more than 50% duty ratio (or some other arbitrary thres...

A few fun text adventures

I just stumbled upon these, and gave them a go, in part due to bringing up the idea of having some text adventures on the Uzebox. Choice of Robots: https://www.choiceofgames.com/robots/ . It is not free, however the first two chapters are to get you immersed, and it is quite cheap. If you like the i...

Re: 80 column text mode at quite high resolution

Here you go, a terminal character set attached. To use it, like before, videoMode80core.s, line 138, include it. Then in videoMode80.c, also modify the appropriate line to read SetFontTilesIndex(0); as this character set has the space at position 0. I attached the source image as well, that's how it...

Re: 80 column text mode at quite high resolution

This is really insane and clever. My head hurts trying to understand it. You can already do inverse if you start playing around with it: Set up a display list, then you can (should be able to unless I bugged it!) set any global Foreground / Background color Sorry I wasn't clear, I meant an attribut...

Re: The site is under attack

Wow... That bandwidth figure. Seriously, are we keeping up infrastructure for human beings or this ridicule trying to find loopholes to drop a load of spam posts (e-mails, whatever) everywhere? If bandwidth is starting to become a problem I seriously don't know what we could be doing at all. Apart f...
