Re: Microdisc replacement project

IIRC some people asked a couple of manufacturing companies and, though producing it seems feasible (I think all the components can be found quite easily, being the LCD display the most difficult one), it was quite expensive (can't remember how much, but in the range of the 200 USD?). The culprit was...

Re: The Hobbit on Oricutron

I think Slicebit is a member (rings a bell), so he might help.

Now that I think about it I should register too... I am spanish and it is a retro forum where they speak about the Oric! :shock:

Re: EDOS machine

I think this was commercial. I mean they worked for software houses that wanted to keep their stocks small, but that does not mean they won't need inlays and nice boxes...
They just had to store inlays and boxes

Re: Sprites

One sec... I paint the background tiles then copy the background buffer to the second buffer and then paint the sprites and finally I copy this second buffer to the screen. Why these two backbuffers? This will reduce your framerate dramatically... Is it to avoid redrawing the background tiles? (so a...

Re: Sprites

Hi Algarbi. Clearing and dumping the buffer with the above routines is slow, but you should get something like 12 fps easily. You may want to check this alone (without drawing background or sprites) and see there is no problem here. Then you may want to add the drawing of the background. This could ...

Re: RND function always gives the same sequence of numbers..

Would something like this: 4 S = INT (1+RND(PEEK(866))*1000) solve the problem? Well it would need a try. Not having also a seconds counter is a problem (you'll get the same value during a whole minute), but I'd do something like: 1 RND(-PEEK(866)) Which should reset the seed to a "position&qu...

Re: OSDK 0.20

Confirmed here, Dbug. It seems the images folder must exist (though the roms folder in the parent directory shared with Euphoric works). I get this error: Unable to open 'roms\jasmin.rom' Unable to open 'images\statusbar.bmp' Not sure why it complains about the jasmin.rom file being missing, because...

Re: OSDK 0.20

Well Oricutron failed with two errors: not finding the ROM folder and not finding the IMAGES (the directory was empty). And I first tried with Skool Daze, so it is not related to a disk configuration.

If I have time I will make further testing trying to isolate the issue.

Cheers.

Re: RND function always gives the same sequence of numbers..

I am not sure that the Oric's RND function works like that. In the Oric-1 manual it says: RND(n) will produce a random number greater than or equal to 0 and less than 1, if n is a positive number. If n is a negative number, then the random seed is set to a particular number, and subsequent positive ...

Re: RND function always gives the same sequence of numbers..

I think you are right Symoon. All the procedural random generators which start from a given seed act like that. Will probably happen on the real hardware too, unless some kind of source is used to generate the seed (such as VIA timers). But even with that, I doubt it will change anything when using ...

Re: OSDK 0.20

Hi Dbug... Just made a first quick test of OSDK 0.20. It compiles Skool Daze smoothly and correctly. Disk-based tools still give me problems under win64 (tap2dsk and old2mfm are called). Changed the make.bat to call dsktool and it worked. Also when selecting Oricutron to execute the compiled file, i...

Re: Oricutron 0.9

Hi Symoon. This is strange, as I can load the wav file generated by tap2cd despite its location (which is not in my tapes folder, btw). I never remove the turbo-tape option, though. Just start oricutron, select Insert Tape on the menu, select the file on the dialog box and CLOAD BTW Xeron, thanks fo...

(Continued) See that window? We can make it look like a bit light blue (as if we could see the sky through it). The method is simple: just complement (set the 1's to zeros and vice versa) and set the inverse bit on the scans with yellow ink and you'll have this: window.png Looks better, doesn't it? ...

Hi all. As many people have asked about this, I think it would be nice to explain a bit more in depth how the AIC mode works.
