- 0.140u2: f205v, Smitdogg and The Dumping Union added clone Megatouch III (9255-20-06 ROD, California version).

- 21st October 2010: Smitdogg - We got a couple of old Megatouch sets in a package deal. The first set I'm sure is correct and runs fine, it's Megatouch III (9255-20-06-R0D). The second set might be just a mixmatch of old chips. I can get it to come up on the boot screen as Megatouch III 9255-10-06-R0G but I don't think it's a correct set. The main number naming isn't consistent.

Changed parent description to 'Megatouch III (9255-20-01 RON, Standard version)' and clones '(9255-20-06 RON)' to '(9255-20-06 RON, California version)', '(9255-20-01 ROF)' to '(9255-20-01 ROF, Standard version)' and '(9255-30-01 ROE)' to '(9255-30-01 ROE, Standard version)'. Renamed (megat3a) to (megat3ca) and (megat3b) to (megat3a).
