What an amazing entry this is. I notice it's very personal but that does not make me blind to the fact that you really enjoyed this game. Your entry is valid even though i might not have the correct console to stream this game.
I have a little brother myself which i used to play games with, so i can relate to the relation factor in your story. It's one of the few things me and my brother shared in our youth. We used to play alot of Smash Brothers back then on the nintendo.
While writing this i realize that i might be able to find this game on the PS4. They launched a new project where we can find older games for free as long as we pay the monthly subscription. I will see if your game is in their list and i will actually give it a go if you become one of the winners.
Thank you for participating, great entry!
There's always emulators...
I know there are, i haven't used any for years now but i'm sure i'll be able to find them. I used them a couple of years ago to play gameboy games on.
When in doubt, TheISOZone can help you out. They've got a good community over there.
