Nestopia and Санчез say that iNES Mapper 148 is a cost-reduced version of mapper 146=79=NINA-06 that omits the bus conflict prevention circuitry. This is also known as the hardware that Tengen used in their PCB 800008, containing their version of Tetris.

The only game that exists in GoodNES and Nestopia's database that actually needs this definition is Sachen's Mahjong World; all others that use this hardware are accurately emulated using CNROM. Bizarrely, Nestopia's database decided it was more correct to put Panesian's oversize CNROM games here instead.
