AFCC Check
Press and hold Left + Right + Up + Down on the second controller (of course, you can't do that on the regular controller), then reset the console. A message "AFCCチェック" ("AFCC Check") will appear. Press A on the first controller to start the test. The program will perform a check of the mapper internal RAM at the 0x7F80-7FFF area, which is present on the "TAITO X1-005" (mapper 80) chips. This game uses another mapper chip "TC0190FMC" (mapper 33) from the same Taito, but all mapper operations are duplicated. Any mapper operation will write to the mapper 33 registers and mapper 80 registers as well. So game virtually able to run on any of these MMC chips.

On the mapper 33 this check will always fail and "NG" will be displayed on the red background and the game will be locked. If there is a proper RAM initialization, then test will pass with the green screen with the "OK" message on it for a short time and then return back to the title screen.
