Re: Arculator v2.2 released!
Arculator v2.2 is now available. Apropos of nothing... I noticed this bug while using the game CONQUEROR : The tank controls ( key H to move left tank track forward and key K to move right tank track forward ) do not work if using ARTHUR 1.20. Certain other keys do work, though, which suggests that...

Re: New: fully documented source code for Lander
Great attention to detail. Excellent to see assembly source for Archimedes games becoming available (whether decompiled, or new projects).

Re: pseudo scanlines
I would have thought pulling in a hardware based shader effect from another source would be fairly simple, but I don't know SDL! Doesn't MAME support various effects and as it now supports the beeb except a few 6845 issues, it might be good to experiment with. Ultimately, Tricky, yes a proper shade...

Re: pseudo scanlines
B-Em currently has a scanlines mode, though it is not as advanced as you describe here. To try it: Settings->Video->Display Type->Scanlines Yeah - a controllable percentage would be nicer, since I think a "full" black scanline is overly harsh in appearance. But thanks for pointing me to t...

Re: pseudo scanlines
Perfectly good question. It's arguably just as valid to invert the percentage. Swings and roundabouts!BeebMaster wrote: ↑Thu Nov 16, 2023 10:43 pm Perhaps I don't understand the terminology, but why does the higher percentage dark scanline produce a lighter scanline?

pseudo scanlines
Anyone have a hankering to enhance a BBC Micro emulator with pseudo "scanline" effect? In lieu of a sophisticated "CRT filter emulation" graphical layer, one conceptually easy way is: A. Use a line-doubling approach. B. Apply a percentage bias with the "raster" displaye...

Quite slick.

Below is a "pseudo-amalgamation" of many common feaures of emulators. "Our" crop of Acorn 8-bit and 32-bit emulators cover some... but not all of these items. Is there any emulator capability that is on your personal wishlist ? :?: ( My wishes are CRT shaders and monitor barrel d...

VIDC shrunken screen modes
For the VIDC screen modes targeted to standrd monitor type, can these be customised (via registers) to reduce the memory footprint used? In other words, use fewer rasterlines (vert) or narrower lines (horiz) ? I know that the Beeb's CRTC can do this, but I'm not sure about the Archimedes's VIDC capa...

It's probably theoretically possible to write HostFS for RISC OS 2, but it'd be more difficult both to develop and to use. Good explanation, thanks to you. I guess if one was to programme code for Arthur / RISC OS 2 ... you would simply develop against RISC OS 3 (i.e. to benefit from th HOSTFS tran...
