Regarding the disk controller, there's a known issue on the Telestrat compared to the Atmos + Microdisc, where accesses to the FDC registers misbehave if the instruction is not aligned on a multiple of 4 bytes (I think, Chema can correct if I'm wrong) in memory, not sure what the actual cause is, b...

That is what I always stated, and almost lost my neck for it many people can't stand that some consider FPGA as emulation, even if hardware emulation.

Hey rampa! Nice to have you here

What a question, I'd say emulation, but then I'd have a mob trying to hang me XD

Welcome to the forum!

Oops! I missed it... anyway Happy New Year to all this marvellous community!

Also, Oricium is all text mode. All sprite masking & animation is done by redefining characters. Even the pixel scroll in the starfield.

And the radar at the bottom.

The code is in the repo, if you're interested.

Merry Christmas to all Oric lovers here!!!

Oops... good luck! I just hope everything goes smoothly. We don't want any disruptions in our favourite forum

If I can do anything to help or test...

Are you using the original 3" drives? Maybe the disks are not in good condition. I either use a Gotek (which works like a charm) or 3.5 drives and disks I write with write2dsk. If it were a matter of amplibus (bus signals, delays...) you would probably have a machine that does not boot to the i...

Scrolling is a pain on the Oric. Twilighte's swiv demo is a masterpiece and it is probably the slowest scroll at which a game would be playable... or enjoyable. If you want to go fullscreen (almost) then it's probably a no-no. I used text mode in Oricium, which gave me 50 fps of scroll for only the ...

Great for the disk loading part!!

I know nothing about js isometric engines, sorry. I hope you finally find a suitable one.

Indeed... that would help in writing a disc clone Oric utility. I always wondered if read_track/write_track only would do, and feared it would not. Well, at least with existing FDCs, it doesn't. I had updated the very first post of this thread, so we can have a sum-up of the situation. Yes, I under...

This makes sense - first to use whole track reading just to get the "description" of the track (i.e. number of sectors and their size) and then to read every sector individually. Very interesting! :) Indeed... that would help in writing a disc clone Oric utility. I always wondered if read...

This is looking fantastic!!! The graphics you mention are for animation of doors when opening and for the pyramid that represents a passcode you can get. Other objects are sprites, if I recall correctly, not as tiles. The special tiles that are invisible, but treated as obstacles, are there to preve...

Some more questions: 1) Where do I find info about wcmap.exe and wcgraph.exe used to compile the game? Or are these te executables of WHITE and NOISE? If not... where can I find such executables? I was only able to find sources. They are in the repository https://osdn.net/projects/oricsdk/scm/svn/t...

Nice you are interested in porting this... it was my first game for the oric, written so many years ago when I promised Fabrice Frances I'd learn asm :D It started as an isometric engine you could use from C (Thus the name NOSIE - Novel Oric Isometric Engine). When developing I quickly noticed I had...
