Many years ago (1980s), David Allport did an MA thesis on the Bhuvanadīpaka at Oxford.  He did a critical edition of the text based on MSS in the Chandra Shum Shere collection, plus maybe some photocopies supplied by David.  I imagine there's a copy of his work in the Bodleian.  His introduction might give you some information about Siṃhatilakasūri's vṛtti, though I'm only guessing.
Best,

Dear all,
I am working on the full translation of the mathematical commentary  by Siṃhatilakasūri (13th CE) on the 
Gaṇitatilaka by Śrīpati (11th CE).

. According to Pingree, Siṃhatilakasūri  wrote a vṛtti at Vijāpur (Gujarat) in 1269 on the jyotiṣa-work Bhuvanadīpaka by Padmaprabhasūri.

 I wonder if anyone knows  whether such commentary has ever been published or if it is possible to locate the manuscripts.

Thank you very much in advance,
sincerely,
Alessandra.
