The article does mention LoRom and HiRom, I imagine you're talking about the same thing.

No that's something else, LoROM and HiROM differ in how the ROM data is mapped into memory, while FastROM and SlowROM differ in the bus speed. You can have Lo/Slow, Lo/Fast, Hi/Slow or Hi/Fast carts.

They're related but not the same. This wiki page explains LoROM and HiROM; FastROM is explained by this sentence.

> Different address ranges are accessed at different speeds, and the speed of the ROM at banks $80-$FF may be changed with register $420D.
