Grab the latest esxDOS here: https://drive.google.com/drive/folders/ ... 1RPQkJtWWc
Or take it here: download/file.php?id=549
Then update the ZX-UNO with it.
Take the files in the attached file and put it on your SD card.
These files works fine with UNO and Blue. It has a patch to load 128Kb games that requires 128 ROM.
See that it has esxdos.sys and esxmmc.bin that needs to be renamed as esxmmc.rom in the tbblue folder.
The bin is the file contained in the TAP file to update the UNO.
After that you will have all files with same version (bin in the UNO flash memory, rom for Blue and sys for both).
