Freshly-Picked Tingle's Rosy Rupeeland

Nintendo promised a sequel to the stellar Game Boy game Kaeru no Tame ni Kane wa Naru ("For Whom the Frog Bell Tolls"), but for some reason it turned out to be a game starring Tingle. Set in a corrupt Hyrule, this game is actively advocating capitalism, sex (no, really), and slavery. A sequel about Tingle being a sex offender has been since released exclusively in Japan, for better or worse.

Koolo-limpah!

Debug Menu
Use the following Action Replay code in the European version, with English language enabled:

Press L + R during playable sections to get a debug menu to appear.

Map Select
Upon triggering the debug menu, a map select with many pages will appear, available by pressing R. Selecting one will warp you to a different map. There are some leading to cutscenes, and some maps will outright set your rupee count to 0, insta-killing you, hence the need of using an Action Replay code for infinite rupees to get to these maps. But there are some interesting unused areas, such as:


 * 07: A terrain select test map. (?)
 * 35: An over-populated test map. It tests some 3D and upper-screen animations, but also has the map select from the tower top.
 * 77: A testing map lacking any collision whatsoever. There are some dancing, thankfully non-functional pedo-bears and many mini-Tingle. Said mini-Tingle creatures makes you and your companion (set by default to the green troll) walk in a pre-set path, likely for event testing. Another warps you to the city entrance, and two trigger cutscenes, one of which is the intro using a placeholder Japanese name.
 * 83: Another test map with scrolling. There are three clones of Tingle (OMG): the first is actually the "NUL" ghost, who triggers a non-functional conversation screen, the second one sings the "Secret Discovered" jingle from Zelda, and the third one is probably a corpse. The chests and the many girls (probably Tingle's harem) offer you rupees and various items. Each girl has the same thing as the chest behind her, but you can always talk to the girl again and get more. Aside from two jars, there are also two unreachable yellow platforms on the staircase.
 * 89: A very odd, non-functional map, with duplicate Tingle actors.
 * 68: Unused map.
 * 74, 72, 61, 14: Glitchy maps, with Tingle duplicates and messed collision. 61 even says NUL.
 * 71: Copyright Screen.

Sound Test
If you press B you'll get to a screen with version information. If you then press A you'll open a full fledged sound debug menu... in Japanese. The second-to-last option has a sound test.
