I had a rather strange discovery a few days ago.
It's commonly accepted (at least on the Bootleg Wiki and the Telefang Wiki) that Telefang Power was used to create Pokemon Diamond and Speed was used to create Jade.
However, the copies (in Chinese) I own are swapped around based on the headers. I compared my dump of Jade with another verified dump of Jade in Chinese by comparing their headers and watching their intro sequences.
The other weird thing is that the Telefang wiki mentions that Jade has been known to cause dumping issues by having an incorrect ROM size in the header. However I've found the reverse, my copy of Jade dumped as 2mb which it should and Diamond gave me a measly 64kb file.
Not sure why but there you go.
