Re: publicité mensongère mon c..

My account is blocked so I can't contact admins.

I know nothing about Thailand.

I want to spend my energy on finding a way to make this dream become true. I don't want to struggle in a nightmare.

I have enough difficulties with my own algorithms before trying to understand Facebook's ones.

Re: loading from disk

You can get a rough idea from booting Blake's7. I have neither disk nor Cumana reborn nor cumulus to test and I wonder is the reading from an emulator is relevant. By the way, I realise that the link to blake's7 on oric.org looks broken: https://www.oric.org/software/blake_s_7-2422.html It leads to...

Re: loading from disk

Or the answer of @ jbperin 's question is: for 32 kBytes we need 8*0.2 = 1.6 seconds :). Hey ..it sounds good I'm working on a new concept for adventure games on Oric and I need to load 32kB of memory from disk at each scene. So I was wondering if the gameplay would not be too slow .. 1.6 seconds i...

about 6KB/second
Thank you very much for this valuable information.

By any chance, would you have the same measurements for Erebus or Cumana (I don't remember which one is capable of reading .DSK files) ?

Re: Oricutron 1.0 (EDIT: Now 1.2)

On my french azerty keyboard: I type "AA88" on the BASIC screen .. then I press F2 to enter the monitor and then I type again the sequence "AA88 Here's what I get on Oricutron 1.2: Oricutron12.PNG In...

Re: Oricutron 1.0 (EDIT: Now 1.2)

Hi, I'm facing a difficulty with the oricutron 1.2.4 that comes with OSDK_1.19 : I can't find a way to type the symbol "_" (underscore) which is terribly frustrating when it comes to debug with symbols in monitor. I use a french (azerty) keyboard which seems to be properly recognized by Oricutron be...

Re: little sound demo

The most impressive sample I heard on the Oric is of Warhawk. It sounds very good indeed but I think it is chiptune rather than sample. I've never known Twilighte but it seems to me that he had worked on both capabilities of the AY PSG. The chiptune approach with Sonix or SoundTracker The sample ap...

I use a french (azerty) keyboard. It seems well recognized by Oricutron because when I press a "A" it's a "A" that...
