Exceptional, best vintage emulator on the App Store!

It’s really cool to think how far we have came in terms of gaming in the last 20 years. 7 systems seamlessly on 1 device is just… amazing. This application brings so much joy to me, playing my childhood DS games. I ended up losing all of my childhood games on a flight when i was about 12 years old, and since then had been wanting to play the games again. I ended up loading all the games that I had lost into my library on the application 🥹 There are no bugs and the AirPlay integration is so cool, it just has a bit of an input delay.


One thing I wish was changed: when AirPlay is being used with a controller on DS games, the “lower-half” of the DS screen is not displayed, which is quite annoying. I think the expected behavior should be to have the “top-half” screen shared to the AirPlay device, while the “bottom-half” touch sensitive screen is present on the phone, so it is still able to be used.


Regardless, this app is the best thing to hit the app store and to hit the gaming industry in a really long time, and I’m excited to see how much further the developers can go with it in terms of devices and functionality. I will happily make a Patreon donation to promote the development of this application. :)

SHRUMPL ,

nds got screwed by the new update

on the previous update everything worked fine, had no problems with apple tv connectivity or loading saves. this new update comes out and all my saves are incompatible (fair and understandable) but now every time i try to load any new saves i made after this new update the whole app crashes and renders that save unusable. (saving through the game and not the app can fix this but it was annoying because it worked just fine before) also every time i would stream the game to my apple tv before this update, wether with controller or not would have absolutely 0 problems besides some latency. ever since this new update it’s been extremely laggy, (to the point where it’s unplayable not just a little bit of latency) and to top it off some my controller buttons will cease functioning when entering a game and i have to go back to the menu to re map it to find out it was mapped and just stopped working. to then have 0 issues remapping it, meaning the controller and connection to my device is perfectly stable. OTHER THAN THAT, top 5 apps on my phone n i absolutely love it. this alone tho makes most of my games unplayable for the time being, unless using the touch screen and phone screen. still possible but a little annoying since it all worked so well jus yesterday :(
