The Cutting Room Floor/Gamepholio

Gamepholio is (as the title of the game suggests) a portfolio of games, you can play solitaire, chess, flip the cards, and even spades, you can also play mahjong in the Japanese version.

This game was made in Chile and wouldn't be released in Japan until 8 years later, this game has since fallen into obscurity until it was ported onto other consoles via the GG flashback brand (marking it the first time to be released overseas), which brings back the slot machine that results in a higher age rating, the GG flashback version wasn't released in Chile due to legal issues.

Unused Music
A piece of ear-bleeding music meant for an early title screen, the samples are stolen from SimCity and Super Mario Kart, which could be why it is unused.

Regional Differences
Due to the game having a different publisher in Japan, all references to Chilevisión were changed to Futaba.

The language difference doesn't count.

Logo
The logo was changed accordingly.

Title Screen
Aside from the logo being translated and PULSA START being in English, the PUSH part in the bottom text had been moved left by 8 pixels.

Menu
Monopolio was renamed to dice roll due to legal issues against Monopoly.

Mahjong
Mahjong was playable in the Japanese version.

Anti Piracy
If the game detects it was pirated, the data cannot be saved in the dice roll mode.

Region Lockout
If the game detects it is running in PAL, then an error screen will appear, the Chilean version is black and Super Famicom is misspelled as Super Famikon (the romaji of the Japanese name) and Chilevisión is spelled without an accented letter (due to the font not having special characters), the Japanese version is in English and fixes the typo, Chilevisión was also changed to Futaba Games.
