The '''[[wikipedia:Watara Supervision|Watara Supervision]]''', also known as the QuickShot Supervision in the UK and as the Travell-Mate in parts of Asia, is a monochrome handheld game console which was introduced in 1992 as a low-cost competitor for Nintendo's [[Game Boy/Game Boy Color emulators|Game Boy]]. It came packaged with a game called ''Crystball'', which is similar to Atari’s ''Breakout''. One unique feature of the Supervision was its TV-Link peripheral, which allowed the console to be connected to a television and its games to be played in limited colour, a handful of years before Nintendo’s own Super Game Boy. It featured very similar capabilities to the Game Boy, but with a much bigger and slightly higher resolution screen. Sadly, it was much blurrier as well, which did not help its sales, already hampered by the lack of recognisable titles and the overall poor quality of most of its games. It later received a minor hardware revision in the form of the Magnum Supervision, for which only one exclusive game was developed, ''Journey to the West''.

The latest versions seem to be relatively accurate, with the dev claiming to have full compatibility with the entire commercial library, including the Magnum exclusive. However, the GBA port is extremely still very slow and there is has no sound. There is no UI either, and no option the DS version seems to choose a ROM – it always reads from <code>have its speed limiter set slightly too fast, with all non-sampled sounds playing in an accordingly higher pitch.

Being incredibly rare due to its pitifully low sales, the TV-Link add-on isn’t well understood yet. Currently, no emulator even attempts to support supports itat all, but it is on both Wataroo and Wasabi’s roadmaps.
