Hacking Old R4 card on latest firmware 3DS

[Tattorack]

I have a 3DS XL, not the new kind, with the latest version of Luma and the latest 3DS update.
Recently I found a really old R4 card.
On the card it says "R4 3DS upgrade". A little red "new" banner on one corner. Other things written on it are "SDHC" in large font, "Revolution for 3DS DSi XL/LL DSL DS", "RTS LITE real time save."
I found the official page for it here: https://www.r43ds.org/pages/R4-3DS-RTS-New-Label-Firmware.html
But it says their driver only supports up to firmware v4.10.0-10. I tried the driver but obviously didn't work.
I also tried RetroGameFan's Multicard Update, both the regula SDHC and the R4i SDHC version. Moreover I also tried the latest 2020 official R4 SDHC firmware (not meant for this card).
None of them worked.
Card is probably far too old, but I thought I'd give a shot asking here anyway. Maybe there is a work around.

EDIT: Thought I might mention I also have a really really REALLY old TTDS card from back when I got my first DS Lite, though I highly doubt a card speaking in hieroglyphics can be used at all.

Holy crap that worked!?!
Thanks so much for showing me this! I had no idea you could make really old flashcards work. I mean, I got my TTDS card to boot YSMenu! You know how old those are!? Damn!
Again, thanks!
