ROM/RAM Test
All NES games developed by Codemasters are based on the same stub library. As a result, all of these games, including those on multicarts, include a "smiley test" that verifies the integrity of the PRG ROM and CHR RAM chips.
To activate the PRG ROM test, hold Up + Down + Left + Right + A + Select + Start and press Reset. To activate the CHR RAM test, hold Up + Down + Left + Right + B + Select + Start and press Reset. (These tests can also be run simultaneously by holding both A and B, and the results will be ORed together in RAM.) If the PRG ROM checksum matches with the internal value or the CHR RAM chip has no bad cells, the program will display a happy green face; otherwise, it will display a sad red face. The code also attempts to write the test results to an unknown device at $4400, possibly an automated cartridge tester.
Note that the tests cannot be performed with an unmodified controller, as the design of the directional pad prevents more than two directions from being pressed at once.
