Re: Wolfenstein / DOOM for Oric : has this been done?

Regarding the performance that can be achieved, it's really all a question of what you want it to look like :) Basically the key points are: - How "high def" should it be - Do we want fine details (textures, recognizable logos or patterns) - What about shading (dithering or color change b...

Re: OSDK Linux/macOS recent version?

Oh, nice, thank you for your answer!

I guess it should work fine under macOS then.
Are your changes already integrated in the defense-force SVN repository?

Re: Wolfenstein / DOOM for Oric : has this been done?

So classic Bresenham makes a decision every pixel with negligible setup cost. Run slice makes a decision only every line, but incurs a setup cost. In a generic line drawing algorithm you'd probably switch between them based on a heuristic like major axis length is at least 8 pixels, major axis leng...

Re: Visual code plugin for cc65

I started a visual code plugin for OSDK (xa syntax) last month https://github.com/oric-software/osdkVsExtension I don't have the time to work on it, but if someone want to work on it, let me know, i will add rights on oric-software group I started giving it a look but it looks like this is essentia...

Re: Reverse engineering the 6522 VIA chip?

My, that would be quite an undertaking, I hope you are assisted with good vision analysis software during this task. ;) Do not take my opinion as representative of the community in any way (I only infrequently dabble in Oric stuff) but although I find the idea of reverse engineering the 6522 chip fa...

Re: Experimental very fast tape loading

I see, interesting, thanks for your detailed answer! So this is essentially a combination of several enhancements: On the encoding side: * some data compression (RLE + dictionaries) * more compact audio encoding (less samples per signal) * higher encoding signal frequency And on the decoding side I ...

Re: Wolfenstein / DOOM for Oric : has this been done?

Otherwise all I can think of is keeping the walls so that there's only a single colour per column, and using a comparison of each frame's new span list to the previous to cut actual drawing time down to the absolute minimum. It doesn't bode well for trying to add non-wall objects though. Rendering ...

Re: Wolfenstein / DOOM for Oric : has this been done?

It was mostly my way of saying that "but I did not find any indication that anyone attempted to at least make a technical demonstration of these games on the Oric." was not a correct statement :) Indeed my search was not thorough enough. ;) I must admit I need a refresh on some details Th...

OSDK Linux/macOS recent version?

Hello kittens! I am starting to get warmed up to code a bit on the Oric using the OSDK but since I live in a macOS world I wanted to know if there was a Linux/macOS version available which contains the recent v1.1 OSDK changes? Sir DBug pointed me to this old post http://forum.defence-force.org/view...

Re: Demo page

Looks nice but on macOS/Safari there seems to be some overlap on the "tabs" and the ASCII art seems to spill over the background on the right.

Note that the orange band on the attached image is just me selecting text accidentally.

Wolfenstein / DOOM for Oric : has this been done?

Hello, I did a cursory search for "wolfenstein oric" and "doom oric" on Duck Duck Go and https://pout.net but I did not find any indication that anyone attempted to at least make a technical demonstration of these games on the Oric. There have been some attempts on the C64, VIC 2...

Re: Oric related links of interest

Good point, added CLK to the list! Thanks! [...]One more thing, recently I found in my archive an internet snapshot of all Oric sites dated June 2001. Since then many of the sites are disappeared, so maybe this can be interesting too. This looks like it could be a really important archive. Looking ...

Re: Steam/GOG

I've ticketed it for myself, which generally means it'll get done because I'm loathe to close those things without resolving the underlying problem. Nice! Thanks. It's definitely Microsoft BASIC, and I strongly suspect that Microsoft didn't fool for Commodore's trick of a one-off purchase of unlimi...

Re: Steam/GOG

[...] Actually, thinking on that, I guess I'd need to change two lines so that it wasn't looking in UNIXy places for the Oric system ROMs, and if I'm doing that I might as well support bundling of a default configuration file so that you can launch it directly from the executable rather than from a...
