Re: C64OS ..

Have bought C64OS by the way, so soon hope to have also hands on experience with it. Have a Commodore collection next to a.o. my Orics.

Re: C64OS ..

Agree on most parts, but the mouse pointer would be an issue. C64OS uses hardware sprites for the pointer and a software sprite for the Oric will be hard to combine with text mode. Of course solvable by making a less nice one character pointer, but is less precise and nice. You could do all in hires...

Re: Oric Screen Editor: editor for creating Oric Atmos text screens

Impressive menu / windows system, well done! Thanks! That part is actually not new, already used it in my last year Ludo release. Refined it a little bit to cope with the inability to use lines (as I want to avoid characters that the user might have redefined) and some other tweaks, but in essence ...

the selected menu item loses the highlight color when you show the menu list Solved. Schermafbeelding 2022-08-18 090948.png Will post the new image on release, but Github already updated.

Good one. Will look at it and see if that is an easy fix (which I think and hope) or not.

Video demo:


Recorded from a real Oric Atmos and Cumana Reborn, so yes, it works on real hardware as well ;-) At me at least.

Re: Using overlay memory: how, tips and possibility for direct save/load

Yay! Seem to have solved also that final issue. Found that also the escape chars count in the character count (which of course does make sense, else a diskname with colours would take more room than one without). Also forgot to actually adjust string length in C for it, so it had no trailing zero to...

Re: Using overlay memory: how, tips and possibility for direct save/load

Great progress: disk parser almost works! It now works great on the OSE system disk: Schermafbeelding 2022-08-17 175711.png Routine now puts its output where the program wants it, can fit a lot more files by having three columns instead of two (gaining the space by skipping the extensions and file b...

Re: Using overlay memory: how, tips and possibility for direct save/load

Update: found the cause of the inconsistent byte grabbing. It was not the speed of the code that was the issue, it was that apparently that SEDORIC routine really does not like if you change the X register ;-) Did as suggested: first just a byte grabber, nothing else. Works fine, consistent stream c...

Re: OSDK 1.19

You do not need to do it for me, but an XP is that vulnerable that it can literally infect everything connected to the same network in seconds. Hence the ‘only use if isolated’ part. And you honestly can not blame Microsoft for not securing such an old OS to all new modern threats. Things were much ...

Re: OSDK 1.19

Am I again the one to point out that running Windows XP in 2022 is really not a good idea, unless you completely isolate it from anything on the rest of your network (and even then)? If your PC is really that old that it does not run Windows 10 (must be old then, because even my 2011 PC is running W...

Re: Using overlay memory: how, tips and possibility for direct save/load

To test the speed theory, one thing you could do is to keep the byte fetcher hook, but just have it call the original function directly (check that it still works fine), then add a delay loop, and increase the value until it stops working. If it gets slow without even stopping to work, it means it'...

Re: Using overlay memory: how, tips and possibility for direct save/load

Makes sense DBug. Using zero page I want to avoid because I already had conflicts with the SEDORIC code when I tried that (and safeguarding ZP values every time will certainly make the code slower), but self modifying is certainly possible. Good suggestion. However, if I do not first solve why the d...
