USB-NES lite Version 0.42 now available!

The first USB-NES lite devices will be sold with firmware version 0.42, which adds support for MMC5-type NES games, as well as TENGEN’s RAMBO series board sets, taking the supported mapper count to over 40. The mirroring flag in the iNES header is now cleared when reading ASIC-type mapper game carts (as opposed to previously always being set). An optional setting has been added to enable the NES 2.0 mode, as well as limiting the maximum vaules of the bus timing parameters to 1 microsecond.
