jmr2704/Collider-bsgs — reverse-engineered prompt

Build me a Windows x64 Nvidia GPU tool that searches Bitcoin puzzle key ranges using the BSGS method. It should run from the command line, let me choose GPU threads, blocks, GPU IDs, range start and end, baby table size, hash table size, and either one public key or a text file of public keys to search.

I want it to save progress automatically to currentwork.txt so if the app crashes or I stop it, I can continue from the last saved state as long as I use the same settings. Save generated baby and giant arrays and hash tables to disk so future runs start faster. When a private key is found, write it to Found.txt.

Include a help screen, sensible defaults like the original Collider, and example commands for Bitcoin puzzle ranges 120 to 160. Also add the 120 bit random test mode. Build it in PureBasic for Windows and CUDA Nvidia cards, and keep the educational use disclaimer.
