So this rom is indeed bad (hacked), and the one from MAME with CRC=1d123be6 is the proper dump. Ikari_01 analyzed both roms and found the current one in the DAT to be hacked: "so the no-intro / goodROM apparently has the rom type flag set to slowrom instead of fastrom (which the game uses) and an SRAM size check patched out. It writes a test word to SRAM and then reads it back from the same address instead of address+0x800 to check correct mirroring."

Correct file added to Datomatic. Big thanks to everyone involved in righting this error. :3
