## HiRom and LoRom

There are two main types of SNES cartridges, the SNES community refers to them as LoROM and HiROM cartridges. Both have different memory mapping.

In LoROM mode, the ROM is always mapped in the upper half of each bank, thus 32 Kilobytes per chunk.

The banks $00 – $7D (address: $8000 - $FFFF) hold continuous data, as well as banks $80 - $FF. SRAM on the cartridge is mapped continuously and repeatedly - 8 Kilobyte of SRAM are mapped at $0000 - $1FFF, $2000 – $3FFF, $4000 – $5FFF and so on.
