One of the biggest things that have been discussed a lot is whether or not it would be possible to emulate the DS on the PS Vita and over the past two years the developer Grarak has been at work making just that. Last week he released version 0.90 and made substantial progress, I've been following this development from the very start since he suddenly announced on Discord that it was in development for the past 3 months with footage of Ace Attorney running on the Vita in April 2024. With version 0.90, games run much better than they ever have on the emulator and even 3D games prove to be able to run at a playable speed albeit with occasional slowdowns.
