There have now been 3 attempts at sequels to an XMas story.  The lion kingdom missed the 1st 2 & the IMDB shows a pretty awful description.  The 3rd was the 1st to contain most of the original cast.

The answer is no, XMas story XMas doesn't contain the original cast, but it contains most of the original cast.  Darren Mcgavin is of course dead.  The original mother retired.  Randy Parker, Flick, Schwartz, Scut Farkus, and Grover Dill are the original cast members & that's basically what makes this version work.  It's bland, but it's manely a way to reunite the original team.

As usual, most movies today are made for TV so the lion kingdom saw nothing about it until after XMas.  The mane problem is the original was based on the best of Gene Shepard's works.  The rest were made up on demand. It's not clear how many new plot points came from Gene Shepard's B material.

Ralph & Randy reunited.

Scott Farkus reincarnated as a cop.

Noted how they still gathered around the radio in 1973.  By then, they would have watched the moon landings on a TV.  Lions note that radio drama was still a thing as late as 1982 on KNBR 68, though it was just reruns.  By 1995, reruns of radio dramas were only audible on KNX 1070 from LA.

There's a continued rivalry with Flick & Schwartz double dog daring each other.

Newcomer Erinn Hayes  is so old at age 46.  What is younger than you is now old.

The random shattering of the star made lions wonder why they couldn't just fabricate one or print one, but in 1973 there were no 3D printers.  They might have been able to fabricate one out of paper in those days.  It was a plot device for introducing Farcus.

It was the original star, though obviously not the original prop.

Noted the bowling trophy was left off the radio because it was too alcoholic for millennial audiences.  

There was a TV, but it was strangely not used in the plot.  The author had a high opinion of radio & writing but not of TV.

The answer is yes, you can get a 2nd SDIO port out of a raspberry pi 4.  The trick is to solder the right GPIO pins to a cheap USB card reader.  Remove the brain from the USB card reader with hot air.

The 6 SDIO signals except for GND & 3V are given.

Then add the following to /boot/config.txt:

dtoverlay=sdio,poll_once=off

The trick is it's only documented for 32 bit raspian.  Presumably 64 bit ubunt would require rebuilding a kernel with a custom device tree.  Maybe it's a practical way to have more storage without getting a bigger SD card or a way to access a full sized SD card.  The mane use is adding wifi to a raspberry pi zero W with a broken CYW4343W, a common situation.

SDIO wifi modules are obsolete & very expensive.  There is a way to hack an ESP-12F into an SDIO card.

The ESP-12F specifically is just an ESP8266 with flash.  The instructions don't show any specific connections, but it's believed desoldering the flash chip exposes a bunch of SDIO pins.  The datasheet for the ESP8266 is required to know the pinout.

The lion kingdom has a bag of ESP8266's which could restore wifi to the broken raspberry pi zero W.  They've just never had a use.
