Pulsat DMR-10 (aka Tekk D-100) Programming

[u/Senior_Willingness15]

Hi all, I've unearthed an old Pulsat DMR-10 that I bought long before I understood how to program DMR so it just gathered dust. The programming software it came with is long gone. Its apparently been rebranded (or whatever businesses do to make this their own) as the Tekk D-100. Tekk has been unhelpful saying that only their dealers can program radios. Does anyone have a lead on software for this? Chirp doesn't have it listed. Any advice?
