...go someplace and just die.
Barring that, it sounds like you need to find an old computer to borrow, or get Windows 7 Professional which will allow you to download and install XP Mode from Microsoft. That could take care of the firmware package, but I'm not sure what you'll need to do to get WMP10 onto your current 'puter. You'll probably need to do a Google search for that.
Recently I was given a DJ15 that would not come out of rescue mode. I formatted the disk,reloaded drivers and a 2005 DJ Explorer Firmware app. I managed to get it out of rescue but it wouldn't drag/drop files into the library from my W7OS Toshiba LT. I attempted to upgrade to dj ditty firmware based on my service tag but the install failed and now its stuck in rescue again. whenever i reboot it flashes "firmware problem" and goes straight to rescue. Realizing its old and not supported by w7(needs xp sp 1 or 2 and WMP10), how can I get it to reload firmware and where is a firmware program for it that will work on W7?
