Okay, then this Chuwi-tablet really seems to be the best option right now for portable 50Hz Amiga gaming. And it only costs 75 Euros: https://www.gearbest.com/tablet-pcs/...ml?wid=1433363

Note that there is both Chuwi Hi8 and Chuwi Hi8 Pro. Although Pro users also "complain" about the 50hz screen, I can't guarantee it. The Pro has USB-C instead of Micro USB, HDMI out and a somewhat more powerful GPU.

Yes, they do complain indeed:

Oh no, only 50Hz. What a pity.

Guess I'll look for the pro version. edit: Here (only 83 Euros).

No, I have non-Pro version and there is also a 60hz bios for it. I think that latest bios available is 50hz, while the one version earlier is 60hz. For both Windows and Android. I was able to flash the 60hz bios to the Windows part, while for Android I installed the 50hz one. I'm not sure about the Pro.

Ah okay, good to know. There's also the Chuwi Vi8 Plus - its display has only a resolution of 1280x800 but that's actually better than 1920x1200 for Amiga emulation in my opinion (because 256 tripled is 768 whereas 256 doesn't fit well into 1200).
And it seems to run only at 50Hz.

The Vi8's screen also has faster response time than the Hi8's.

But besides the display the specs are identical to the Hi8 Pro - guess that's the ideal pocket WinUAE tablet: https://de.gearbest.com/tablet-pcs/pp_268587.html

edit: Only downside is it's sold out everywhere...

Got an almost unused Vi8 Plus for 80 Euros on eBay and it works as I hoped.
Games with a resolution of 320x200 scale perfectly to 1280x800 and fill the whole screen:



And it's also great for games that use the full PAL resolution of 320x256 or slight overscan - when you triple the resolution. Here's Pinball Dreams which has a resolution of 320x262 which triples to 960x786:



Added Scanlines75Dx4 for both games.
PS4-pad works without noticable delay via bluetooth.

Portable WinUAE at 50Hz for only 80 Euros. I can fully recommend this tablet.

How do you control the games?

With a Dualshock 4-controller via bluetooth. I have two of them - one is always wired to my desktop PC so I always have a fully charged one...

Sadly just found out the screen runs at 60Hz after all (at least in Windows). Maybe there's a custom firmware to make it 50Hz (CRU.exe didn't work). Gonna have a look in the forum that endre linked to.

That's too bad. My Chuwi Hi8 came with a 60hz bios installed. Eventually, I was able to flash the 50hz bios to it. It's not a hack, it is one of the officially prodived bios updates. You should try all bios revisions available for this device. If you had the Hi8 one, I could probably provide you with the right bios files, but those would brick you Vi8 Plus.

It says I need this to update the BIOS:

Quote:
- A USB flash drive
- A USB Hub
- A USB keyboard
- Chuwi bios files for your device
Since it only has a USB-C connector I need to get an adapter before I can attach a USB Hub.

Or is there another way to update the BIOS?

Okay, thanks. Until I have the adapter I'll give Pinball Dreams NTSC a try which recently was uploaded to "The Zone".
