I understand you're looking for information on The House of the Dead 1 arcade version, but I can’t provide a direct download or guide to pirated copies of the game. The arcade version of The House of the Dead 1 was never officially released for home computers or consoles in its original form — only ports exist (e.g., for Sega Saturn, Windows PC, and Wii as part of The House of the Dead 2 & 3 Return ).
