From Mini-Tool Collection; "'jag' is also an abbreviation, and it stands for.....'just a game'. yes! a little game for you. this program also for action replay freezer only. actually, if you pack it with any packer it may work with all cartridges. load the game same as 'jap v2.0'. the inspiration to code this game came to me when i saw 'minesweeper' for windows on the pc... i decided to code a similar game for c-64. i think most of you know the rules, so here i'll give you the keys used:

main menu:
----------
crsr up'n down - move through options return - select option crsr right'n left - change numbers (only when option selected)

game:
-----
crsr-keys - move the cursor
return - uncover the piece
space - mark the bomb
space on the marked piece - cancel mark¨
run/stop - exit to main menu"
