I'd have to check what character results, but yes, the XEP80 doesn't use OLDCHR either as the cursor is managed on the XEP80 by hardware cursor. That being said, the XEP80 also does other weird things, like extending logical lines on move right. Altirra could also use OLDCHR/OLDROW/OLDCOL, it just doesn't right now because the existing virtual screen implementation was based around a hardware-style cursor instead of a framebuffer cursor. It's just getting composited, though, so no reason it couldn't. This was already on my radar because it's also necessary to correctly emulate some weirdnesses when S: is used to target GR.0, which is popular in BASIC games. Some even do weirder things like draw lines in GR.0. Quote Link to comment Share on other sites More sharing options...

I know there is the scan feature, but there are some stuff it does not detect. Does the "portable install" Altirra.ini trick not work for this? I've been keeping Altirra and most Atari related stuff on a Google Drive mapped to G: so I can hop between devices easy peasy Quote Link to comment Share on other sites More sharing options...
drac030 Posted July 8 Share Posted July 8 2 hours ago, dmsc said: Yes, on the VBXE it puts the wrong character, but still it shows "some symbol" to indicate the line continuation, so it is mostly ok: It is, as you wrote, "wrong character", though. This means that this trick is of no use to the CP/M terminal, which must print whatever a CP/M app wants printed there, and not just "some symbol to indicate the line continuation". Of course, one can emulate OLDCHR by converting its value to and fro (ATASCII<>internal code), but I am quite reluctant because a) it is pure waste of runtime in most cases, b) and especially it would be on a device where the cursor is implemented in hardware thus no form of OLDCHR is needed at all (XEP).

phaeron Posted July 15 Author Share Posted July 15 https://www.virtualdub.org/beta/Altirra-4.30-test17.zip https://www.virtualdub.org/beta/Altirra-4.30-test17-src.7z Adds support for J(atari)Cart and DCart cartridge types. All of the new cartridge types of 128K or above are flashable. The flash configuration is not well defined for these types, so they have been mapped as follows: J(atari)Cart 128K: 39SF010 on 256K board (6 bit banking) J(atari)Cart 256K: 39SF020 on 256K board (6 bit banking) J(atari)Cart 512K: 39SF040 + empty socket on 1MB board (8 bit banking) J(atari)Cart 1MB: 2 x 39SF040 on 1MB board (8 bit banking) DCart: 39SF040 8 Quote Link to comment Share on other sites More sharing options...

Mclaneinc Posted July 15 Share Posted July 15 (edited) Not logging as a bug report, just in case they are dud images. Tried the new JACASRT support, a file called Eclipses JACART 512 booted fine. But 2 other files that I think I got off a thread on here Test JACART 32 and 64, both caused crashdumps. An acid DART booted to a ready prompt., I presume it works? Anyone have links to a few more test versions of these carts as CAR? PS, Avery, get some sleep, the beta's have been flying out Thank you Paul.. Edit. Posting dump and used cart files just in case..

+Philsan Posted July 17 Share Posted July 17 Avery, it has been brought to my attention that a part (@ 03:20) of brand new cool demo Rewind 2 is different in Altirra. With Altirra (and on real hardware with Sophia 2 conected to RGB monitor) there are tiny blue horizontal lines (please magnify Altirra's screenshot). On real hardware with s-video and CRT there aren't those lines. Thanks! Quote Link to comment Share on other sites More sharing options...

On real hardware with s-video and CRT there aren't those lines. I don't have a machine that can run this demo, but I mocked up the display list and DLIs and got single-line high stripes, which then would get blended to two-line in PAL. The DLI handler is deliberately doing this, ostensibly to apply a slight gradient for depth. Did the machine without stripes by any chance have a VBXE in it? The demo is using a trick where a missile is locked on for longer than usual. This is what it looks like with emulation of this enabled and disabled, with PAL artifacting enabled. Notice the difference in color. Quote Link to comment Share on other sites More sharing options...
+Philsan Posted July 18 Share Posted July 18 Thanks for looking at this issue. With my machine, PAL 800XL connected to Commodore 1084S monitor with s-video, no tiny blue lines. With another machine of mine, PAL 800XL with Sophia 2 connected to the same monitor, there are the lines like in Altirra emulator. In this video, made by someone with a PAL 800XE + VBXE, no lines. https://youtu.be/UuWEEms1IX4?si=1s3EPsH7WSyM9uk-&t=213 BTW, big scrolling bars are grey, I think they should be blue like in Altirra and in my stock hardware.

Can you provide a good quality picture from the 1084S? The reason I mention VBXE is that it is known not to emulate the trick that this demo is using, so that would be expected. 1 Quote Link to comment Share on other sites More sharing options...

I probably mentioned it elsewhere, but I'd also vote for that. It's not only the bi-color highres, but also proper interlace mode that it has, and generally having Sophia2 emulation would allow for quicker testing of Sophia calls in software (not a common thing to explicitly interface to Sophia from one's programs, but I in fact did that in Popeye). At the same time, my experience is that despite a simple interface it has some quirks too (which by now I have forgotten what they were).

I don't understand what difference you're referring to anymore. You said that there were no blue lines on your actual hardware, but they're very clearly in the picture above...?

You've been implying that the blue lines aren't showing up, and they clearly are: Turn on PAL artifacting on Altirra, and you will see those single lines of chroma get averaged to double lines like your display is doing (which not all displays are guaranteed to do).

+Philsan Posted July 20 Share Posted July 20 In fact with PAL artifacting tiny blue lines aren't visible and image is like my monitor and s-video, thanks!

You'll have to experiment with the settings in Adjust Colors. This is a tough case because of the reliance on blended colors and high saturation.

+yetanothertroll Posted July 23 Share Posted July 23 ABBUC's software contest signup page lists a bunch of ways emulators including Altirra don't work the same as real hardware, especially PAL. How many of these might still be relevant in current versions? https://abbuc.de/aktivitaten/software-competition/ Quote Link to comment Share on other sites More sharing options...
