Get a free software called MAME (Multiple Arcade Machine Emulator). It emulates all the electronics of all those classic games. You just need to download the ROM data files which were taken from the actual machines game code and use them in MAME to recreate the game exactly like it plays on the hardware. It can be a little technical to setup but with a little work you can have hundreds of those old school games ready to play just as you remembered them. Lots of old school fun with MAME.
