Due to several issues with all three of these cores developers have been given permissions to close out tickets for these three cores as long as there doesn't appear to be any real issues with the achievement. Although these cores are not officially supported you can still earn achievements with them and are considered play at your own risk. Duckstation - The Duckstation Core in RALibretro while a popular core for players playing PS1 sets has been officially sunsetted by the LibRetro team. They are replacing this core with swanstation which the creators are continuing to release updates and bug fixes for. Since developers cannot properly troubleshoot issues with duckstation it has been deemed unsupported. A full write up written by televandalist can be found below: For the past several months, there have been tickets opened by players using DuckStation and a lot of them have been closed due to the dev not being able to reproduce the issue. Since we're in the middle of a dev event in which the primary focus is getting the ticket count cut down, a lot of us have been able to narrow down issues with multiple sets. It's also allowed us to confirm that there is something wrong with the achievement processing in DuckStation. We don't know what the issue is because we currently don't have a way to monitor the behavior of the RAM/achievement processing in DuckStation. However, a lot of the reports have been similar: the achievement didn't work, the player reset or tried again later, and then the achievement worked. Some examples: https://retroachievements.org/ticketmanager.php?i=43728 - this is what got wilhitewarrior talking about it on 12/4/2021. https://retroachievements.org/ticketmanager.php?i=43741 - This is from earlier and the player had provided the most info we've had on the issue. He even says that he got an error in the emulator regarding achievements. and here's a few random tickets that all point to this issue: https://retroachievements.org/ticketmanager.php?i=42759 https://retroachievements.org/ticketmanager.php?i=40684 https://retroachievements.org/ticketmanager.php?i=43558 https://retroachievements.org/ticketmanager.php?i=43067 https://retroachievements.org/ticketmanager.php?i=43035 https://retroachievements.org/ticketmanager.php?i=42943 Total mysteries from a troubleshooting standpoint. Deeming it as not officially supported was the right call. If this issue is resolved, then the story will change. NEStopia: Sram is not exposed. Sameboy: The core is very unstable and at times can cause memory addresses to become jumbled causing achievements to not pop properly.

Anyway, thanks for the info. xcommander Joined Aug 5, 2020 December 5 2021, 9:19pm @MagusPC: Well, according to this ticket, the standalone is affected (I have no idea about the libretro core). bimmy December 5 2021, 9:27pm Well, without Duckstation, there's no more reason to play Psone games with RA. surfgirlgamer15 Joined Jan 4, 2017 December 5 2021, 9:27pm, last edited December 5 2021, 10:11pm [Spam removed by admin] MagusPC December 5 2021, 9:35pm @xcommander: Interesting, thanks! hmm maybe it could be related to some options DuckStation comes with like Overclocking or CPU Emulation. I remember Resident Evil DC 1 had a false opcode execution when entering the first red room on the right where you can find the Ink Ribbon and a Zombie lays on the floor. Overclocking can also cause a game to crash or creating bugs. It would be good to know if any of these functions were active when attempting the Achievement.

Yes, CPU overclocking is a big issue, and I only have seen issues with Duckstation core when I was overclocking. What happened is that a memory address was 1-frame forward what it was supposed to be on regular 100% CPU clock, so an achievement didn't triggered because the conditions were expecting that address to be in sync with the others, but maybe that was a very specific case of inacurracy. Freakservo December 5 2021, 10:33pm, last edited December 5 2021, 11:15pm Shame about Duckstation. It was the only emulator that seemed to function with the Ridge Racer 60FPS demo. =( I mean, Swanstation works too, but I get odd screen resolutions with it. Peculiar thing.

Should still be fine to play on, just some tickets may get closed for emulator is/was unstable. Freakservo December 5 2021, 11:18pm That's good for games like Incredible Crisis, which needs Duckstation to get through one of the minigames. SlashTangent Developer Joined Oct 1, 2020 OP December 5 2021, 11:21pm As I said in my post you are free to keep using these cores. They are just play at your own risk. Freakservo December 5 2021, 11:22pm Sure. Sometimes I misinterpret 'unsupported' with 'being totally removed'. XD My bad.
