eNES: NES Emulator Retro Emu

Trying not to be a Karen, I downloaded this game to play NES games and there is just two options: Fire, which is just a pixelated gif of a fire. Or Scroll, which is just nothing but scrolling through NES nonsense, can someone please help me?

I tried playing Metal Gear and had to save everytime I got to a new screen so it wouldn’t erase my progress because it kept crashing at random. Also the D Pad is pretty annoying since you can’t just slide your finger over the thing to change direction, you have to remove your finger from the screen entirely to stop and press another directional arrow. If you could fix both of those things I think this would be a great emulator for iOS.

If I need to switch directions I have to completely remove my thumb from the screen instead of just sliding on the D Pad. Makes most games difficult to play and makes platformers impossible

It turns of while playing

im playing double dragon on this and so as many nes games you need the double click of a and b, i mean in double dragon a is for kick b is for punch and to jump you have to click them both at the same time and in the case of this app it is not possible, i really had to play with three fingers even tho i managed to finish the game with this devestating liabillity i hope you guys fix it as soon as possible, love the app tho.

Like how

Download nes Mario Bros. Runs well, but the b and a button cannot be pressed at the same time. So you can’t hold run and just rock your thumb to jump. Makes OG Mario pretty hard.

I've tried a ton of diff methods when I save to files and save the rom in the apps main directory that is the only way I can get the game to show up and it does recognize it but when I go to launch it I get this error message that the file doesn't exist or is corrupted when they clearly are valid NES rom files that do work lol

I like this emulator
