This is pretty cool actually! Nice to have a centralized source for these things instead of having to dig through Chinese eBay equivalents.
I do have a question, though: I noticed that when it was first discovered, you had posted some photos of the cartridge for Blood of Jurassic by Shanghai Paradise. Unfortunately, due to Photobucket's shutdown as well as general link rot, the links no longer work. Would you happen to still have them? I can understand if you don't, that was over a decade ago, after all.
