Hey welcome to planet virtual boy, im new as well i joined yesterday 😛 my virtual boy finally arrived from ebay (i live in Australia, ordered it from America)
i absoulutely love it, it is so much different to many other consoles, such a pitty it got discontinued, the 3d effect is awesome different to other consoles, i payed about 150 dollars in total for it including postage, it included 2 games teleroboxer and marios tennis, man they must of been very cheap back when they got discontinued..
anyway about some of your questions
with the problem about your virtual boys right visor being glitchy, dimming and if your seeing vertical lines through it i would suggest looking in the forums of this site
go to forums > main virtual boy discussion > The VB glitchy display problem..
it is a sticky its up the top of the threads.. have a look there, hope that helps.
now with your other questions:
1) The home brew games on this site are made from awesome people and you need to buy a flashboy cartridge wich you can find more info about on the left side bar under sections > hardware >flash carts
you basicaly put the game from the computer on it and play it on the virtual boy.. Blox 1 and 2 are great games that a guy has made!
i dont think they have put the homebrew games on old carts or new carts how ever that would be a great idea!
2) yeah some prototype games are around by serious collectors, like faceball and dragonhopper, no one has managed to get a copy of it fake or what not, if someone did have the prototype of the game they would ‘dump’ it onto the internet for download, then you could put it in a flashboy cart and play it off your virtual boy..
3)yeah like i said check the forums > main virtual boy discussion > the VB glitchy display problem thread see if what they have their to fix it helps, theyre pros 😀
4) VB cart ‘sleeve’, what do you mean in as sleeve? a sleeve to put the whole cartridge in or one of those dust protectors that stick on where the pins to connect into the virtual boy would be, if so its them – you can find them on ebay i think its a set of 4 for around 10 dollars.
i hope i’ve helped a bit in answering these questions and i hope you enjoy the site as i am, its great i love it, so much information and things all cool gadgets people have made to make the virtual boy even funner!
have you seen my question thread right under yours about japan import games, i need the question answerd if you have any idea what the answer is to a few of the questions i have.
basically, are japan import games from ebay english or japan language, because the games have like english text for the title then a bit of japan under them, as with the virtual boy i bought both of the games are made in japan yet the only japan language you see is when you start it up and it says in english read the manual or something then under it it says the same thing in japan.
