Over Obj Debug Options (NES) Romhack

Over Obj contains a hidden Debug Options menu containing Muteki (invulnerability), Heranai (infinite lives), Stage Select (allows selection via “Left” and “Right” when hovering on “Continue” on the main menu), Rest (0-9 number of lives), BGM (0-17 music tracks), and SE (0-15 sound effects). It is normally accessible at the title screen by holding down “B” and pressing “Right” 9 times, “Up” 2 times, “Left” 2 times, “Down” 9 times. This patch bypasses the need for inputting that button code.

Use either the bps, ips, or xdelta patch depending on your needs.
