WURM: Journey to the Center of the Earth

The Core ain't got nothing on this, yo.

Build date


What appears to be a build date near the end of the ROM. As it happens, this was a good two years before the game's release; according to the game's designer, this was because of a bugfix that took an unusual amount of time. This also goes against the more common practice by having the date stored in the game's graphics rather than as plain text in the code.

Unused Text
At the ROM location an unused text string exists: "VISUAL DEMO". No code that uses this string still exists.

Sound Test
At the title screen hold Up + A + B on the second controller. Press Select to switch between the SE and BGM modes. Press Left or Right to change the music index. Press A or B to start or stop playing sounds accordingly.

Stage Select and Invulnerability
At the title screen press Up + A + B on the first controller and Down + A + B on the second controller at the same time. Press the B button to change level and press Select to toggle invulnerability on or off. (You can tell if it's on by the word "TEST" appearing on the screen)
