Problems "booting" latest SD image

[odflor]

Hi Pals:

I have two SD, one with a early version that's works very well and other with the latest SD image that don't "boot"

I only ajust the conf.txt to set the Raspberry PI 3B.

Only is necessary to copy the content of the .zip file into de root of a formated SD card?

Is there other thing I need to do to work?

I have a Commodore 128 NTSC.

Copying all files on the SD card should do the job. I recommend to keep the settings from this line in config.txt:
"include sidekick64_rpi0_c128.txt"
... these should work on all RPis.

I think there are problems with some kind of sd cards.

I usually use a 32gb sd card.

maybe formatting at lower capacity helps, I don't know if there are any incompatibilities of SD cards and RPis... (at least there is nothing I could do from the software side)
