Re: CUmini - my Oric storage emulation project
Quick update. Emulated BIOS ROM is working and now the Microdisc device ROM runs upto the point where it starts to access the FDC register emulation stubs I currently have there. This should be past some of the overlay RAM initialization, so we got some indication that is working as well. Time to s...

Re: Cannot change OSDKADDR value
I tried with $400 without any problem.
Have you tried the osdk_showmap?

Re: CUmini - my Oric storage emulation project
Thanks that's very useful. I managed to squeeze a few extra PIO cycles, so we're good for 0x310-0x31B space. Initially it spanned all the way to 0x31F. It will be technically possible to remap the device registers to any other 16 byte aligned address at run time, but that will of course break the u...

Re: CUmini - my Oric storage emulation project
There's a more complete list somewhere, but can't seem to find it, but there you go: https://wiki.defence-force.org/doku.php?id=oric:software:memory_maps#page_3_i_o These are some of the reserved ports for some peripherals, and not being able to use other devices because address decoding is not done...

Re: CUmini - my Oric storage emulation project
For the menu/setup/select floppy, I guess you could use some additional "hidden ROM" that you only map when you want to show the features of the system, but you would still need to save the zero page, stack, graphic memory, etc... to avoid corrupting the main application running. That bein...

A cheap combo disk+tape is what has been missing for a while, looking forward to see how that develops

Re: French to English Translation
As for Oric.org, it has never been clearly defined what defines an entry (pretty complicated actually) - should a single page hold all the languages versions, all the publishers, and so on. So I suspect you'll find different ways of updating software. Different entries are fine, as long as the fiel...

Re: ULA, bus conflicts and the expansion devices
I remember reading some post from someone who worked at Oric support, and one common issue was Oric Atmos and Microdisc not working together, so they would do some tweaks, replace capacitors/resistors/whatever until the two work together properly, then send it back to the customer. Fast forward a fe...

Re: Upgrade Time: Encounter
Glad you both like it.
Regarding easter eggs, that will depend on how much progress I can get on the game, and how much space left on the floppy, but I have a couple ideas.
Now, if that was a reference to Easter next week, I fear I don't have any eggs around!

Re: Upgrade Time: Encounter
And that's what I came up with.
Still not 100% finished, but at least there's no more large expanses of white everywhere!

Re: Launch c program with parameters
As far as I know, neither SEDORIC or TDOS have a way to pass parameters to executables when they are launched. That being said, I did a quick test using a comment after the command, and it seems to still be present in the command buffer in page zero. image_2024-03-16_110350897.png As you can see bot...

Re: Upgrade Time: Encounter
I'm completing the unfinished scenes. This set of views is "blank" on the right, where the player cannot go, and I need to find what to put there.🤔 Could be some fields, some river, trees, smoke stacks of a factory, mountain... What would you see in this British countryside? image_2024-03-...
