  In the last two years the dark dimension scenario has emerged as focal point
of many research interests. In particular, it functions as a stepping stone to
address the cosmological hierarchy problem and provides a colosseum for dark
matter contenders. We reexamine the possibility that primordial black holes
(PBHs) perceiving the dark dimension could constitute all of the dark matter in
the universe. We re-assess limits on the abundance of PBHs as dark matter
candidates from $\gamma$-ray emission resulting from Hawking evaporation. We
re-evaluate constraints from the diffuse $\gamma$-ray emission in the direction
of the Galactic center which offer the best and most solid upper limits on the
dark matter fraction composed of PBHs. The revised mass range which allows PBHs
to assemble all cosmological dark matter is estimated to be $10^{15} \alt
M_{\rm BH}/{\rm g} \alt 10^{21}$. We demonstrate that due to the constraints
from $\gamma$-ray emission, quantum corrections due to the speculative memory
burden effect do not modify this mass range. We also investigate the main
characteristics of PBHs which are localized in the bulk. We show that PBHs
localized in the bulk can make all cosmological dark matter if $10^{11} \alt
M_{\rm BH}/{\rm g} \alt 10^{21}$. Finally, we comment on the black holes that
could be produced if one advocates a space with two boundaries for the dark
dimension.
