MamePlayer

All games have been emulated with MameUI, I have never used cheats, TAS or Tool Assisted either before or during the game, use only the SaveState.

-- What are MameUI?
MameUI = Multiple Arcade Machine Emulator a program that enables your computer to function as the old arcade machines.

-- Where can I find the emulator and games?
Go to Google and search MameUI and Roms.

-- What are Roms?
The roms are the games.

-- What are SaveState?
SaveState = Save the current state of the game an option available to anyone with the MameUI.

-- What do I need to make videos like yours?
1 - Any version of the MameUI emulator
2 - Your favorite video recorder
3 - Your favorite video editor

-- How can you not show the video when you make a SaveState?
;)

-- I saw that hit you and not die because?
This is a side effect of SaveState limited only to the edges but the game still has to be completed with a capacity. You can try and see for yourself.
