6 in 1 (Caltron)
|6 in 1|
Also known as: Caltron 6-in-1 Six in One (US, Myriad), Real Player's Pak/Pack (AU), Multi-Ação 6 in 1 (BR)
6 in 1 is a mediocre game compilation by NTDEC released under one of its many aliases. It's not outright terrible only because most of the games are ripoffs of other games, with the exception of Magic Carpet 1001. It's also one of the rarest NES games in history, but the Myriad version is even more valuable, even though it's the same game with a new label plastered onto the cartridge that doesn't even cover the old one properly!
At least it's better than Action 52. WHOOPS DID I JUST SAY THAT OUT LOUD
The cart contains the unmodified PRG data for Pokey starting at 0x38000 in the ROM, which was one of the first unlicensed NES games and was made by NTDEC in 1989. The only thing it's missing is some of the graphics, which can be found in Asder 20-in-1. This suggests that Caltron intended to include Pokey, but it was cut due to time or space issues.
Leftover Mega Soft logos from Cosmos Cop, Balloon Monster, and Porter. They were all originally released separately on cartridges under the Mega Soft name, and the logo graphics can still be found in those games.

Found at 0x7210 in the main menu's PRG data, which suggests NTDEC planned to (or did?) release this cart under the Mega Soft name in 1991.
