+CharlieChaplin Posted July 13, 2020 Share Posted July 13, 2020 Besides, now that I have the special AVG SIO-cables (two selfmade ones and a much better looking one from Mr. Robot), I would like to try its function with some ATR images that do require RAM under the OS... Looks like firmware 019 does not recognize the SIO cable nor support such ATR images that require RAM under the OS ?!? (Or I am doing something wrong and/or must delete OSXEX first or whatever...) Where can I find the firmware 020 (no matter if alpha, beta, etc.) and do some beta-testing...? I also have a few .CAS files here, but prefer the much faster CSIM versions running from disk/ATR (afaik, no turbo tape can reach 19,200 Baud). But I am not using any ATX images...

Jeffrey Worley Posted July 15, 2020 Share Posted July 15, 2020 I have added the sio connector to my AVG cart and would like to try it out. Is the beta firmware available for me to play with? Best, Jeff Quote Link to comment Share on other sites More sharing options...
Jeffrey Worley Posted July 16, 2020 Share Posted July 16, 2020 (edited) I am probably doing something wrong, but I fired up the AVG primarily to use as a DT80 cart for my ATR8000. It appears that the DT80, which is a 4k cart, is not supported. The AVG reports "cart type not supported". Am I dumb or is this a fact?

tmp Posted July 16, 2020 Author Share Posted July 16, 2020 one should use car files instead of bin/rom since they contain cart type in the header (in this case it's a kind of a bug since apparently the smallest rom i had was 8kb so there's no type forcing for 4kb/2kb files, i'll fix that) try using attached car, if that doesn't work, i'll look into that DT80.car Quote Link to comment Share on other sites More sharing options...

What did you do? I renamed the original file to .car and it did not work. This one does. Did you edit it somehow? Thank you!!!!!!! I am getting my CP/M disks sometime very soon and this will make it a heck of a lot more pleasant to use. I once had the original cart, but that is long gone. THANK YOU!!!

Mr Robot Posted July 16, 2020 Share Posted July 16, 2020 A car file is a bin file with a 16 byte header on it that describes the type of cart layout the cart uses. It’s how emulators and multicarts know how to load them. You can save a bin to a car in altirra or atari800 here is the list of cart types https://github.com/atari800/atari800/blob/master/DOC/cart.txt Converting CAR back to BIN is just a matter of chopping off the first 16 bytes. Altirra and atari800 can both do that too. I have a database of every cart (I've ever found) and what cart type it should be. I use a couple of small python programs to convert back and forth depending on the type i need. 2 Quote Link to comment Share on other sites More sharing options...
tmp Posted July 16, 2020 Author Share Posted July 16, 2020 yes, using altirra is probably most user friendly, load rom/bin via "Attach Cartridge", find the type that works and then save it as .car via "Save Firmware->Save Cartridge" 1 Quote Link to comment Share on other sites More sharing options...
R.Cade Posted July 20, 2020 Share Posted July 20, 2020 I have my SIO cable installed now. Can you send me the invite for the test firmware? Quote Link to comment Share on other sites More sharing options...
tmp Posted July 26, 2020 Author Share Posted July 26, 2020 (edited) thanks to @Xuel, you can now play PDM files directly from the cart browser without having to run side loader cart first and then pdm player for side copy PDMPLAY from this zip into the root of your SD card and you should be able to directly run PDM files (you need firmware 0016 or higher) (ESC to quit, SPACE/RETURN for settings) Edited July 26, 2020 by tmp 3 1 Quote Link to comment Share on other sites More sharing options...
Xuel Posted July 26, 2020 Share Posted July 26, 2020 Source for the player here: avgpdm-1.0.zip This includes a rudimentary Altirra custom device which implements the AVGCart streaming protocol. I used it to debug my code in Altirra. I included instructions to install it in README.txt. NOTE: You need Altirra 4.0+ (e.g. Altirra 4.0-test5) for custom device support. 2 1 Quote Link to comment Share on other sites More sharing options...

tmp Posted July 26, 2020 Author Share Posted July 26, 2020 current version is compatible with what fjc's ide player is using (i believe there's such option in the converter) Quote Link to comment Share on other sites More sharing options...

Sincerely Mathy As tmp said, this plays the same files as FJC's PDM Player. You can generate them here: https://lybrown.github.io/fujiconvert/ The bitrate is pretty much maxed out already. It is limited by the PDM playback method. It's 44KHz for mono and 22KHz for stereo. The AVGCart Player can use three different playback methods: PDM (8-bit), Covox (8-bit), and PCM (4-bit). Covox is probably the clearest if you have that extension in your machine. PDM should be better than PCM but I included PCM just for comparison. Currently .pdm files have no way other than file name to identify mono vs. stereo. I think it would be nice to develop a standard header for these files to include this info in the file itself. This could also contain other metadata like Artist and Title. I'll make a proposal later. You can play a stereo .pdm back as mono or vice versa but ideally you'd play back with the same number of channels as used during encoding with FujiConvert. 2 Quote Link to comment Share on other sites More sharing options...
+CharlieChaplin Posted July 26, 2020 Share Posted July 26, 2020 Hello Xuel, does your PDM player a) playback the PDM files directly (in a "fire and forget" style) or does it b) first copy them to an unused portion of the SD-card (contiguously, without DIR, direct sector access, ...) and then play them back from there ? If I had to choose, I would prefer the direct play (fire and forget) method similar to the 50fps / 60fps videoplayer... the other method means more wear and tear for the SD-card. (For example, if I play a PDM song ten times, then it gets copied ten times and errrrm, if I playback all of my approx. 550 converted PDM sounds several times, then they get copied several thousand times and that wears out the SD-card. faster.) Note: I have not used/tested your new player yet, will do tomorrow... Quote Link to comment Share on other sites More sharing options...
tmp Posted July 26, 2020 Author Share Posted July 26, 2020 (edited) yes, i forgot, it uses the same mechanism as avf player so files need to be contiguous on the card Edited July 26, 2020 by tmp 1 Quote Link to comment Share on other sites More sharing options...

tmp Posted July 26, 2020 Author Share Posted July 26, 2020 sure, there's no writing whatsoever the limitation of files not being fragmented comes from playing phaeron's videos, due to transfer speed needed, it was quite futile to try to handle fat cluster chains on the other hand, some time ago i tried to create a fragmented file and had quite a hard time (simply copying files, deleting some and then copying again wasn't working, i had to fill the card to the max, then delete some files and put some larger file in the remaining space), either fs drivers are intelligent these days and try to allocate single chain or i was extremely lucky 1 Quote Link to comment Share on other sites More sharing options...

Mr Robot Posted July 26, 2020 Share Posted July 26, 2020 Well that works lovely! @Xuel I have to hit return/space twice to get the interface to open (1088xel, not tried on any thing else). Is there a way to pass params at launch or some way to set defaults? I'd like stereo to be on by default, that's how I converted all the files I've done.

I'll see if I can debug the double return/space issue. Can you walk me through the exact sequence of keypresses that you did starting from the AVGCart menu? Yeah, tmp and I discussed the possibility of storing defaults somewhere. For now, I'll post different versions of the player with different defaults.
