Emulation

There are a large group of people working on emulation projects for various consoles and home computers. Emulation is a very grey area as regards the legality of machine emulation. The majority of manufacturers of old consoles and computers are happy to allow emulation although certain manufacturers such as sony specifically forbid it.

Emulators are usually either written for a specific machine or range of machines from a certain manufacturer or global emulators which cover a whole range of machines from different manufacturs.

The most popular global emulators are:-

M.A.M.E. - This is a global emulator for arcade game machines. The current version emulates over 10,000 different arcade games. Although mame itself is freely available the required games or roms must be sourced by yourself as the legal situation as regards possession of these roms is a very grey area. Mame can be downloaded from the official mame website. There are a number of "front ends" or derivative versions of mame such as mame32 and mame32fx. Original arcade games were discrete logic boards and as such are emulated in individual chips but later games used optical discs or hard drives to store game data. These are therefore stored in a compressed hard drive or chd. Some of these chd images can be over 20GB in size and so the current size of mame and all the current games is just short of 200GB. There are a number of places to obtain mame roms a search on google will give you a number of options.

M.E.S.S. - This is a global emulator for many home computers and is loosely based on mame and can be downloaded from the official mess website. Again although mess itself is freely available the required games or roms must be sourced by yourself as the legal situation as regards possession of these roms is a very grey area. With mess you will will need not only the games but also the roms from the various home computers. There are a number of places to obtain mess roms a search on google will give you a number of options.

The most popular emulators and systems are listed below on the individual manufacturers pages

Other emulators for other consoles and home computers can be found via google or other search engine.

	Chorley's leading computer shop for Business and home computer repair. Service and Repair of PC's and Apple Mac . When we were looking for premises for 1 Stop Tech shop we had a number of considerations. We wanted to be located in a strategic area at the centre of the motorway network that allowed PJR Micro Ltd to service our business and domestic customers easily and cost effectively. We therefore chose Chorley as this location. As we have continued expanding we quickly realised that our Chorley shop was to small for our purposes. We therefore started looking for new larger premises. There was nothing suitable within the immediate area so we expanded our search further afield, and located a building in Whelley, Wigan which was ideally suited for our purposes which we moved to in 2009. As our business is now going more and more data based we need a premises with fast backbone connection and as the fastest speeds we can obtain at Wigan is 3mb we have amalgamated all our business under one roof at our business service center at Coppull Where we have a 15mb and a 11mb backbone connection. Our Business customers range in areas from Liverpool to Wilmslow and Kendal to York and we have domestic customers all over Lancashire and Greater Manchester. Our new computer shop and premises have extensive offroad parking so short distance to carry sickly pc's.
