R0ger Posted February 5, 2020 Share Posted February 5, 2020 This is very little discussed technique, and it seems very advanced. Do you have some understanding of it ? What intrigues me is there are not just 1 and 0 in the Altirra output. More like several levels (3 or 4). Using debugger I found it does about 4 writes per line, which would be enough for some dithering. Still the code is surprisingly simple and for how complex the sounds are. And it sounds super clean.

abbotkinneydude Posted February 6, 2020 Share Posted February 6, 2020 @xxl, Unless I'm mistaken, the FGTIA didn't ship with any audio circuitry to accomodate the SECAM signal. Would this work if a SOPHIA board from Simius was attached to the FGTIA? Thank you. Quote Link to comment Share on other sites More sharing options...

Kyle22 Posted February 8, 2020 Share Posted February 8, 2020 I would love to see some binary executable files if they do not use illegal opcodes and run on a 65c802. :) Quote Link to comment Share on other sites More sharing options...

xxl Posted February 8, 2020 Author Share Posted February 8, 2020 These programs run on Atari xl / xe, such a programming canon. so it may not work on modified equipment. 1 Quote Link to comment Share on other sites More sharing options...

Why bother? If developers want to lock out upgrades and get a big dick about people begging them not to, let them, and use software which doesn't. 1 1 Quote Link to comment Share on other sites More sharing options...

abbotkinneydude Posted February 8, 2020 Share Posted February 8, 2020 The road1.mp3 sounds REALLY good. The use of the GTIA sound channel reminds me of some of the best use of the SID in the C64 demo Edge of Insanity. This is really, really good. Does a tracker exist to combine the GTIA channel with the regular POKEY channels? Thanks! Quote Link to comment Share on other sites More sharing options...
R0ger Posted February 8, 2020 Share Posted February 8, 2020 I think these are don in 1tracker, see here: http://shiru.untergrund.net/software.shtml I was also able to find this list of atari engines provided by XXL: http://randomflux.info/1bit/viewtopic.php?id=5 There is no tracker doing both, AFAIK. 1 Quote Link to comment Share on other sites More sharing options...

rdefabri Posted March 26, 2020 Share Posted March 26, 2020 I think someone pointed out in another related thread that some games (Whomper Stomper) used the internal speaker for sound. Since later XL / XE models eliminated the speaker and routed the sound through the TV / monitor, does this imply the GTIA could be used as a "fifth" voice or did I read somewhere that you couldn't do POKEY + GTIA sound simultaneously? Really cool stuff. Very surprised it wasn't leveraged more in the past. Quote Link to comment Share on other sites More sharing options...
xxl Posted March 26, 2020 Author Share Posted March 26, 2020 yes, when we change the options in the game Whomper Stomper, you can hear squeak on GTIA ? Quote Link to comment Share on other sites More sharing options...
Kyle22 Posted March 27, 2020 Share Posted March 27, 2020 What I want to know: Are the ILLEGAL opcodes necessary for function, or are they just road blocks to prevent your enemies from running this code? Phaeron kindly fixed one file for me and PROVED that the IllOPs were NOT NECESSARY. This B.S. MUST end. Quit fighting against the Future! Don't be left in the Dark.

If developers want to lock out upgrades and get a big dick about people begging them not to, let them, and use software which doesn't. It's an irrelevant platform with no commercial future. Who cares about being a weird stock machine purist? Modifying the machine was insanely common even in the 80s. Why break compatibility when there's no performance advantage or good reason? I can see not putting extra effort into directly supporting an upgrade like VBXE or something, but to take extra effort to break it is just a retarded waste of time. The GTIA music is kinda neat though. I haven't seen that done yet. 3 Quote Link to comment Share on other sites More sharing options...

Tested it on real HW and sounds like shit. Even on unmodified A800 HW. Tested on emulator (XL/XE mode, stock) and sounds intelligible, but almost no low-freq. to speak of.
