All games I sell have been playtested for a minimum of one hour on the original hardware the game was made for.
If you wish to attempt to run the game in a machine the game was NOT made for, e.g. a PS1 game in a PS2, PS3, etc., then you assume the risk that this game may not work in your machine.
As a seller I have had issues with customers purchasing items without properly looking at both photos and descriptions thus being disappointed or angry when they recieve the item and it is not as they expected.
PLEASE, for both of our time and blood pressure's sake, ASK me anything about my items BEFORE purchasing them.
It will be better for everyone.
