I was hoping to try PB, but I can't get xdelta to patch the game. I've confirmed with NRST and the readme file that I have the correct ROM - both the CDC32 and MD5 match. I downloaded the 2b patch from the website. When I run either xdelta program listed in the readme, it gives me the following error: xdelta3: target window checksum mismatch: XD3_INVALID_INPUT. I don't have much experience with the XDelta format, but I'm assuming this means the ROM is incorrect? Any advice would be welcome, as I'm eager to see what's been done.
