I see that Silverbolt is a TRU exclusive (well, atleast thats what it says on the box). I was wondering if you really need to buy the TRU version, or if there is a code for that character like there is for Ramjet. If there is a person out there that has either of the ds versions, can you confirm the character list, and which bots are unlockable through gameplay, or via code. The box says there are 30 bots all together. Info on the DS versions is very limited it seems.
