According to https://spiro.trikaliotis.net/cbmrom, yes.

We might try to find it by limiting the search area.

I know for sure that 901229-05 did not include it yet.

The -06 ROM only added a patch to $EE40. Instead of JSR to $C8C6
directly, it goes to $FF2F which adds a LDA #$FF, STA $51 before the
JSR.

I am not sure about the intention of this patch, but I doubt it has to
do with the SAVE "@ bug.

So, I tend to believe that one of the 251968-0x added the patch.

Regards,
Spiro.
