Good? I don’t know.

I’ve wanted to love this app very bad, as a sort of more casual emulation fan/player on iOS I struggle with JIT and finely tweaking apps to fit a game. Often times I’ll break my game worse than optimize it. Every time I try and use Folium I feel like there’s an equal combination of my lack of understanding the apps features, and just a lack of customization and options available. Don’t get me wrong, when I look at the EmulationOniOS subreddit and see the developer interaction and how other people’s experiences are on here I’m overjoyed. But since day 1 this app has only been a really nice looking app that can maybe run 3DS games, but never been my go-to. I also don’t know if that is the fault of the specific core that Folium uses, but I’ve had far better success with Manic EMU nearly 100% of the time. And that’s my problem. I spent $5 here, what, 2 years ago? And despite that, I can more easily connect a controller and boot up a game on Manic than I could here, and half the time I can’t even get the touch screen controls/screen layout how I want in the first place at all. I’m not *mad* that I spent those $5, I’m glad to have supported something like this, I’m just disappointed I haven’t ever felt like I’ve gotten a quality product in return for the money.

Tomodachi life wont work

I am currently encountering significant challenges in attempting to open the game “Tomodachi Life” on my device. Despite having meticulously downloaded all the required files and diligently following the detailed installation instructions provided, I am still unable to get the game to function properly. Upon launching “Tomodachi Life,” the screen remains completely black, and the game is entirely unresponsive, which is quite frustrating. Interestingly, I have no issues accessing and playing other games on my device, indicating that the problem is specific to “Tomodachi Life.” I would greatly appreciate any guidance or assistance you could offer in helping me resolve this issue. If you are able to successfully address this problem, I am more than willing to upgrade my current rating from a 1 to a 4, as a token of my gratitude for your help. Furthermore, if you are also able to fix the glitchy behavior in the other games I have, I would be delighted to increase my rating from a 4 to a 5, reflecting my satisfaction with the overall experience. Thank you in advance for your attention to this matter. Lol don’t mind my funny writing but pls help

The update makes control pad a joke

I had been playing Pokémon X for the past couple of weeks after buying the app, aside from the pretty regular, out of the nowhere crashes of the whole app, it was too pretty great. And the controls weren’t bad, until this new update. When I try to select the deep pad down button, and when I try to select the B button, it has an extreme delay, which makes you miss opportunities in playing the game. There is some form of overlay problem on the bottom half of the screen, I am playing on an iPhone SE 2022, but this is a joke. Plus every time I press a button now it has haptics that jiggle, and no one ask for that. And as far as I can tell, there’s no way to turn it off, which I really would love to do, it’s extremely irritating and distracting. Please fix the down button on the deep pad, and the B button delays and tell me how to remove these terrible haptics. If you’re going to do an update release, do through testing, I paid money for this, that means I paid money for you to do your job right. Which you are not.
