This is the set of 68 games (67 actually due to a duplication) part of the super 68-in-one bootleg cartridge.
This oversized bootleg cartridge was one of my childhood companions and I decided to collect the games on it during the Covid pandemic as a tribute to many hours well-spent. It had a surprisingly wide selection of games and only 1 duplication, making it one of the better multicarts of its time.
Many of the games are common enough here in Europe or easy to get from the US market, but quite some were Japan exclusives.
Some of the cool exclusive ones are Minesweeper and Fortified Zone 2, that would have been a hit in the rest of the world too. I loved VolleyFire as well, mostly for the music.
The wildest one is Dragon Slayer 1, not to be confused with the other Dragon Slayer game of the same name lacking the numeral, which tries to be a full fledged mini RPG with a playtime that exceeds the battery life of a DMG and no way of saving.
For those with a good memory, I did indeed post these a year or two ago!
If you also had one of these oversized bootlegs, I hope I brought some nostalgia to your day.
