SainT Posted August 8, 2023 Author Share Posted August 8, 2023 Firmware 23.08.0858 Added extra hardware flag support to debug console Fixed missed COVOX audio on console audio Correctly show 144K ROMs (not as 128K) Added @460 to YM2151 mapper tag Corrected AV-OUT TIA volume such that max volume matches the expected console volume Changed default UI polling to left port only, not both due to ghost button presses on right port Added per-game saving of audio, video and break settings 8 4 Link to comment Share on other sites More sharing options...
SainT Posted August 18, 2023 Author Share Posted August 18, 2023 (edited) Firmware 23.08.1839 Fixed dual POKEY bug, 2nd POKEY now working More Details The only dual POKEY audio demo which I've actually noticed a difference in (thanks to @darryl1970 for pointing it out) is the Popcorn audio demo. Other dual POKEY demos I can't hear any difference, which is odd given the 2nd POKEY wasn't actually producing any audio!

SainT Posted August 25, 2023 Author Share Posted August 25, 2023 (edited) Firmware 23.08.2562 Overhauled audio mixing to improve flexibility Streamed audio (BupChip) now pauses correctly on break More Details There is now support for individual volume control of each POKEY as well as the streamed (BupChip, etc...) audio. For AV out the TIA is also mixed as the 7800 does, so you have external audio sources which are mixed together (POKEY, YM, COVOX, ADPCM) then this is mixed with the TIA last. This means AV out now matches what you hear through the console, however you have control over the TIA volume on AV out as well. One of the more useful features of the new mixing is how the channels are mixed. All channels are mixed as a percentage by their volume and this mix then normalised. The resulting volume is then attenuated by the highest volume in the mix. The upshot of this is, if you turn down POKEY2 to zero, it no longer contributes to the mix and other sounds become relatively louder. In situations where you have dual POKEY, but POKEY2 is only used for IRQ's, then you can remove it from the mix to gain some more volume on other sound sources. When using AV out you can also remove the TIA entirely when it's not used to boost the volume (and quality) of the other sound sources. Audio devices which are not enabled are also shown as zero volume and cannot be altered in the audio volume menu. For people who are only interested in playing the more mainstream games, you wont notice a difference with this update. However for games which use multiple audio sources and POKEY's just for IRQ's you can tweak things to get the most out of the audio. Where you are using internal audio through the console this is particularly useful and Portal is a good example of this. While the TIA is still overpowering on a stock PAL console due to the audio balance, you can at least tweak volumes to get the best out of it. And when you are using AV out you can of course drop the TIA volume and get it perfect. Edited August 25, 2023 by SainT 5 Link to comment Share on other sites More sharing options...

SainT Posted November 7, 2023 Author Share Posted November 7, 2023 (edited) Firmware 23.11.0741 Fixed bug in previous firmware causing the POKEY to be out of tune in some circumstances. Most notable in the title / menu music on E.X.O., was fine previously in 23.08.1839. Edited November 7, 2023 by SainT 3 3 Link to comment Share on other sites More sharing options...
SainT Posted November 28, 2023 Author Share Posted November 28, 2023 (edited) Firmware 23.11.2863 Added support for 2600 EF mapper (Zippy the Porcupine) Added auto-fix for bad headers for known ROMs More Details 2600 EF mapper games are now running, most notably Zippy the Porcupine! And given quite a few people have had issues with 7800 games not running and being confused by the incorrect A78 headers out there I've added known good mapper settings. Any known ROM's with incorrect mapper settings will now be corrected and you will get a warning about the bad header.
