Pop'n TwinBee is a direct follow-up to Detana!! TwinBee.

Stage Select Mode

On the name entry screen, have Player 1 (Twin Bee) type RS018 (JP) or RH018 (US/EU), and hold Select + Y + R shoulder buttton for approx. 9 seconds until the menu appears.

This menu includes a bonus setting MUTEK(I) to toggle invincibility.

Note that both versions list RS018 on this menu even though the European version used RH018 for the name entry.

A similar Stage Select screen also appears in Parodius Da!.

Button Codes

A total of 10 button codes exist in the game: 8 are used while paused, and the other 2 are in the options screen. As of this writing, cheat code sites are missing entries or have errors, so here is the complete list of button codes, in the order they are stored in the programming.

Pause Codes

9 Chibi	Up, Up, Up, Down, Down, Down, Left, Right, Left, Right, Left, Right, B, A, B, A, B, A
Full Energy	Select, A, Y, A, Y, X, B, X, B, R, R, Select
Defeated	Up, Up, Down, Down, Left, Right, Left, Right, B, A The Konami code is a trap!
Defeated	Up, Up, Down, Down, L, R, L, R, B, A It's an alternate version of the Konami code using the shoulder buttons, and is also a trap!
Defeated	B, B, X, X, A, Y, A, Y, Up, Left Yet another unfriendly Konami code, this time swapping the directional and A/B/X/Y buttons.
Add Mini-bees	Down, Down, Up, Up, B, B, X, X, Right, Left, A, Y
8 Credits	A, B, Y, X, R, L, Up, Left, Down, Right, A, A, A
Invincible	A, Y, A, Y, L, R, L, R, X, B, B Enter the code again to toggle it off. It's the same bit setting as MUTEK in Stage Select Mode (bit $01 in memory address $7E0086).

Options Codes

These codes must be entered immediately upon entering the options screen.

Level 8 Difficulty	Press Up, Up, Down, Down, Left, Right, Left, Right, B, A (the Konami code) to unlock the highest difficulty, level 8.
Round Select	Press Up, Left, Up, Left, Up, Left, Left, Left, Right, Right, Right, Down, Left, Down, Left, Down, B. The screen scrolls down to reveal a Round Select. The purpose of this setting is unclear, it isn't a stage select. The value is stored to memory address $7E1FEC.

Sound Test

A sound test mode is hidden just below the Round Select, above. However, there's no evidence of a button code or way to access it normally. Instead, game enhancer codes can be used. After you have entered the Round Select button code, enter Pro Action Replay code 82ED44EE or Game Genie code 3330-1FD8 (Japanese version), or Pro Action Replay code 82ED4AEE or Game Genie code 3330-1468 (European version). Press Start to exit the Round Select. The screen will scroll back to the top and down again to reveal the sound test.

When you're ready to exit the sound test, press Select.

To do: Is there really no way to access this without game enhancer codes? It seems odd when button codes exist for everything else, and the sound test is fully functional.

The sound test appears when $05 is written to memory address $7E1D54.

Demo Select

An unused stage select debug menu. Game enhancer codes are required to reach it as no programming was found that writes screen index $0D to $7E0032. Enter the codes, then pause the game and press Start.

Japanese version

Pro Action Replay: 82B12500 + 82B1270D + 82B12A32
Game Genie: DD84-1F06 + D284-1FA6 + 7484-1466

European version

Pro Action Replay: 82B12B00 + 82B12D0D + 82B13032
Game Genie: DD84-14A6 + D284-1706 + 7487-1DD6

Use the D-Pad to make a selection and press X or B to proceed. Note that Stage 7 is listed but is missing the OK, as the game only has 6 stages. Selecting it will cause glitches.

Unused Screen Index $0E

Memory address $7E0032 holds the index of the current screen (e.g., Demo Select is $0D). A pointer exists for index $0E, the final valid entry, but it only leads to a 6B RTL command which exits without doing anything else.
