From the project
A famicom discrete logic mapper
BNUY-ROM is an homebrew discrete logic mapper for the famicom/nes, which aims to have a similar level of capabilities to common ASIC mappers, while keeping a relatively low chip count. The mapper is designed to be modular, with features that can be included or ommitted depending on the needs of a game. It is similar to BNROM, hence the name.
