Retro / Dual-Screen Emulation on the Galaxy Z Fold 8 (Wide): Initial Impressions

*Disclosure: The Fold 8 is on loan from Samsung.*

When the aspect ratio of the fold 8 inner screen being 4:3 got leaked a few months ago. I immediately thought about retro consoles like GameCube and PS2 and dual screen consoles like the 3DS and Wii U.  I decided to do a quick test to see how each console aspect ratio is on the inner screen.

Test Setup

* Emulators Used:
* GameCube: Dolphin
* PlayStation 2: ARMSX2
* 3DS: Azahar
* Wii U: Cemu (Did not work)
* Games Tested:
* GameCube: Resident Evil 4, Metroid Prime, Metal Gear Solid: The Twin Snakes
* PlayStation 2: Persona 4
* 3DS: Mario Kart 7
* Wii U: Nintendo Land, LEGO City Undercover, Captain Toad: Treasure Tracker (Did not work)
* Controller: GameSir G8 Plus MFi

Note: I’m not testing raw performance here. The Fold8 is powered by the Snapdragon 8 Gen 5 elite , the hardware easily handles 60 FPS on these older consoles

GameCube:

One interesting realization during testing was that the transition to widescreen (16:9) actually began in the 6th generation rather than the 7th. In games like Resident Evil 4, the gameplay is in a 16:9 in a 4:3 container with black bars. Cutscenes across all tested games remained widescreen for a more cinematic presentation

Using the Dolphin emulator was interesting. It’s a mature emulator and shouldn’t have a lot of bugs. But when playing Re4 it seemed to glitch out in the intro cuts screens and added a green color that didn’t exist. Another example was when playing Metroid Prime, the game freaked out and warped the polygons on screen during an early section of the tutorial for a few seconds. Dolphin also didn’t automatic map/detect my controller either and I had to manually map it

PlayStation 2:

For PlayStation 2 I used the ARMSX2 emulator. For it being the newest emulators, it felt the most refined. I had no issues playing Persona 4, it mapped my controller and everything worked.

3DS:

I used Azahar which is a Citra fork. Had no issues like ARMSX2 emulator. What I did differently is playing it in portrait. This solved two issues; one fixed the directions where the speakers were playing, second playing in the correct orientation.  With the 3DS screens they are both 5:3. But it’s still able to fit on the fold8 since the bottom screen scaled to fit the width of the top screen.

Wii U:

This is where I failed. I spent the last 3 to 4 days trying to get Cemu working. With my own ROMs. It did not matter if the ROM was encrypted or not. I could not get it working. This is probably my fault. It’s not that bad since most Wii U games have been ported to the switch and you
