Re: Space Cowboy - Demo [raxiss]

Yeah, TEXT vs HIRES is always the same trade-of, kind of hard to have a slow-smooth scroller with a lot of sprites, in TEXT mode. One idea I had, was to try to do an hybrid mode, with odd lines in HIRES and even lines in TEXT, using the TEXT characters to draw the background, and drawing the sprites...

Web browsing on the Oric?

Some time ago, some people where trying to port Contiki on the Oric, and I seem to remember the main issue was the lack of standard I/O in the C libraries. Since then, there's been the 8bit hub, that has internet/wifi access, so I wonder how doable it would be to get this "filtered web" to run on th...

Re: Unphasing harmonics to rebalance sound samples

What I find funny, is that you started with a square wave, which is exactly what the YM/AY is doing by default: The best way to regenerate a square wave is to actually not play it as a sample at all :D

Re: Oric V23 Modem

You can start shorting only TX and RX to see if the typed characters will be echoed back, if not then do other connections. (...) OTRM is hard coded for 9600 baud, 8 data bits, 1 stop bit, no parity, DTR=0, RTS=1 So, my "new" terminal, the Magis Club, does has a 9600 bauds, 8 data bits mode, and I ...

Re: Request for Help (Pixel-Level Retouching)

Well, it does not look like there is going to be any quick and easy solution... so I am gonna release in current state. Let's hope I will get enough spare time in coming year to make a start at implementing this integrated IDE... The only easy and quick solution would be to have a version of the du...

Re: SampleTweaker

The digiplayer is not a part of the OSDK, thus the tools is not officially part of it either. The easiest way to do the wav to raw is to use something like SoX (http://sox.sourceforge.net) Digiplayer.s is pretty much different in all the versions of my demos, some replay in 8bit using conversion tab...

Re: SampleTweaker

It's mostly that it's a tool that's pretty much unusable by itself, each time I used it I modified it to test new stuff, it only load raw files (so can't load wav, etc...), I would not recommend using it as is.

Re: 2 eurocents question about AY-8912 possibilities

Well, the problem with the nop method of synchronisation is basically you can only do things like my "Welcome", which does some sound but you can't do anything else during that time (or the only you can do is to run something that takes a fixed amount of time). What you want is something that ideall...

Re: 2 eurocents question about AY-8912 possibilities

I had plans, but did not really act on it, so feel free to experiment :) My idea was to find an encoding to basically generate a series to write on A, B, C, A, B, C, A, B, C, ... computing the best combination of values to write to generate a 8 bit quality sample by just changing the volume value, s...

Re: Request for Help (Pixel-Level Retouching)

Since that's for the 8bit unity, technically it's now possible to use a mouse (through the 8bit hub), and even download/upload files, so maybe a proper image editor is doable on the Oric :)

Re: Request for Help (Pixel-Level Retouching)

I don't know if it can help but there's a tool (named Orichir) made by goyo which allows to do pixel level manipulating. https://ceo.oric.org/orichir/ That could help if it had a tile editing mode: Basically what is needed is the tile equivalent of a character set editor, where you can write some t...

Re: Request for Help (Pixel-Level Retouching)

For this type of thing, it's very hard to do without a tool that allows you to see all the pixels change on the map at the same time, in the actual context of how they are used. Side note: On the Oric there's only one control key, on the left side, so it's not ideal with WASD for movement :) Maybe y...

Re: 2 eurocents question about AY-8912 possibilities

I also wonder if it could enhance the sound quality to spread the nop along the loop content, multiplexed with register writing rather then gather them at the end of the loop content. What do you think ? On msx they did exactly that, using some Viterbi encoding. https://www.msx.org/forum/developmen...

The chip is a 27128 UVPROM with a 16k memory, in this case the Erebus don't work, you must burn an other UVPROM with a ROMDIS pin compatible.
I assume that means this Oric would not work with a Microdisc, Cumulus or Cumana Reborn either, it's not a specific requirement from Erebus?
