First off, that cartridge appears to me to be legit. The chips are almost certainly original chips, although they're not Toshiba.
Let me break the logic of this down for you.... Sorry if this comes off as arrogant, but it seems like there's a common misconception about chips' implications.
Toshiba chips are a good indicator of a legitimate cartridge, but not having Toshiba chips are not an indicator that signifies a cartridge is a boot.
If we make the logical argument "Toshiba chips implies a cartridge is not a bootleg," we can also make the converse argument "a bootleg cartridge does not have Toshiba chips."
We cannot, however, make the contrapositive or inverse arguments of "not having Toshiba chips implies a cartridge is a bootleg" or "if a cartrige is not a bootleg then it has Toshiba chips." Hopefully that makes sense to everyone reading.
For future reference, a fake label means nothing; its only purpose is to serve as a sign that a cartridge is worth opening up. A cart that appears to have a legit label with scratched serials likely has a legit label; the only fake labels I've ever seen that could be mistaken for legit was on SVC Chaos carts; both my hacked PLUS 2 version, and a bootleg also found in the "boot or no boot" section.
