[req] SNES stage select codes

[eadmaster]

The following games have a builtin level select which can be usually enabled via complicated button combinations:

• Action Pachio (thanks to nolberto82 for the code!)
• X-Kaliber 2097 (thanks to nolberto82 for the code!)
• Ganbare! Daiku no Gensan (thanks to Hybrid for the code!)
• Choujikuu Yousai Macross: Scrambled Valkyrie
• Kendo Rage (thanks to nolberto82 for the code!)
• Wild Guns (thanks to Hybrid for the code!)
• Psycho Dream (thanks to Hybrid for the code!)
• Magical Pop'n (thanks to nolberto82 for the code!)
• Kid Klown in Crazy Chase
• Pocky & Rocky (thanks to nolberto82 for the code!)
• Spriggan Powered (thanks to nolberto82 for the code!)
• Pop'n Twinbee (thanks to nolberto82 for the code!)
• Super Adventure Island (thanks to nolberto82 for the code!)
• Phalanx
• HyperZone
• Flying Hero
• Super R-Type (thanks to Hybrid for the code!)
• Super Ghouls 'n' Ghosts (thanks to nolberto82 for the code!)
• Marchen Adventure Cotton 100% (thanks to nolberto82 for the code!)

I'd like some Game Genie codes to have the level select menu enabled automatically.
They are useful especially for flashcart owners who cannot use savestates to resume the gameplay...

EDIT:
These games have no password and no hidden stage select menu.
They would benefit from codes to access all the levels or a level-skipping button trigger:
- Magical Quest Starring Mickey Mouse (U)
- Hamelin no Violin Hiki (J) (access all the levels on map code by me)
- Rocky Rodent (U)
- Go Go Ackman (J) [T+Eng1.00_Ackman]
- Firemen, The (U) (Prototype)
- Jetsons, The - Invasion of the Planet Pirates (U)
(i've listed only the games i am mostly interested in)

I could not get the this code work correctly (i've tried pressing select while choosing a player),
the others are working fine.

LMAO. Nolberto breaking the league :P

[eadmaster]

I've just made one myself:

Toy Story (U) [!]
Enable Debugging Features (infinite health + pause and press Select to skip level)
CB35-31BA
DF35-312A
3C35-35FA
CBB4-3514
DFB4-35C4
3CB4-3534
CB2A-C193
DF2A-C1B3
3C2A-C123

Probably not very elegant (i've just started making GG codes a few days ago), but it works!
The original PAR code was: 7E0004:01

there is no need to change the reads to writes

here is something simpler
2D2A-C5F3
ED36-30FA
just by changing the BEQ to BNE and vice verse you can reverse the checks it runs and it will run when its not supposed to
