UPDATED on October 11, 2017 - After a hiatus of nearly a decade, this tool works again. Note the new URL. Thanks to Eckhart Köppen for the cDCL, aka "the DCL that actually compiles!"
This page lets you submit any NES ROM and have it wrapped as a package for use with the Newtendo NES emulator for the Newton (MP2x00 only). Newtendo only works with NES ROMs which use iNES mappers 0 (NROM), 1 (MMC1), 2 (UNROM), and 4 (MMC3).
