Editing Prototype consoles

{{WIP}}
{{Placeholder Section}}
'''Prototype consoles''' are consoles that have had a physical build made but for some reason not been released, Such as lack of faith in the console being successful or disagreements within the company/companies.
Some prototypes do (highly likely without permission from the developers) get sold to collectors, the exact relationship between the seller and the company is generally unknown.

The '''[[wikipedia:Halcyon (console)|Halcyon]]''' is a [[LaserDisc]]-based, third-generation home video game console produced by RDI Video Systems.

The System was planned to be released in January 1985, priced at {{Inflation|USD|2500|1985}}. This would have made it the most expensive console of all time. However, it does not appear that it ever reached retailers, and less than a dozen prototype units exist. Only two games for it were completed: 

*'''Raiders vs. Chargers''' (released in arcades by Bally Midway as '''NFL Football''')
 
*'''Thayer's Quest''' (released in arcades by RDI, then for other systems by Interplay as '''Kingdom: The Far Reaches''').
==Emulators==
MAME can emulate the arcade board hardware and ROMs.

:''Not to be confused with [[Konami M2|Konami M2]], although they do share some history.''

The '''Panasonic M2''', also known as '''3DO M2''' or simply '''M2''', is a 64-bit, fifth-generation home video game console meant to be released by Matsushita (Panasonic) in 1997. Developed by The 3DO Company, M2 featured a CPU comprised of dual PowerPC 602s clocked @ 66 MHz, alongside a custom ASIC chip codenamed "Bulldog", which handled several audiovisual elements.

After system specifications were sold to Matsushita in early 1996, the company made a deal with Konami to produce arcade hardware based on the specifications (See [[Konami M2|'''Konami M2''']]). 

Despite this, plans for release of the home console were canceled in mid 1997, and in October of the same year, Matsushita started marketing the M2 hardware for use in other markets, such as [[Interactive_Kiosk|interactive kiosks]]. However, several games and miscellaneous software have surfaced since, such as "''IMSA Racing''", "''PonPonLand''" and "''VizHouse''".
