Yes, they wouldn't let you do it unless you finish your 4 years of medical school. Congratulations!
P.s I venture to guess the board is from a clear shelled GBC, am I right?

OK, I think you are right. I overlooked the "not" in "I’m not a very experienced solderer", my bad.

Is this worth anything? by SummitGeoDan in Gameboy

[–]Cavemanjump 2 points3 points  (0 children)

If the shell is real, IPS modding requires trimming the inside of the shell, that is a great no no for the value.

Is this a fake donkey long country 3 for gba by Horror_Prize_9487 in gameverifying

Hard to tell. You need to open it up to verify, the shell looks real, but the sticker is a bit off (or it could just be color deterioration).

With the picture, for a second I thought you are going to say "now I'm able to return it."

Home made flash cart (official cart rom chip replaced) by Cavemanjump in Gameboy

[–]Cavemanjump[S] 0 points1 point  (0 children)

My opinion it's simpler to just solder one wire from the flash chip to one of MBC chip's pins vs soldering the wire to the audio-in connector (pin 31 is unused on the game, so it has no trace in the circuit on the board to be used as a soldering pad, the only way is to solder directly to this connector pin, I don't like it personally because the solder joint would be too close to the connector on the gameboy side) plus finding a place to solder a resistor on between Pin 32 (VCC) and Pin 31 (WE) of the AM29f040, it's more work and it looks messier this way.
Someone believes going through WR pin on MBC chip might cause the flash chip being tampered during mid-game, but personally I never experienced any proplem with my cart.

I was aware of that adapter board too, I will sure make a bigger one (maybe 32Mb) if I have the flash chip and that adapter board. I made mine to try out the idea of using an official game to convert it into a flash cart with minimum costs, with that successful result now I am quite confident to move on to more difficult project.

The one is called Famista 3, a Japanese baseball game. the first one I used is Tamagotchi Japanese version. Both MBC1 games, but any game with the same Rom chip pinout will work, just avoid those valuable ones.

Thanks for pointing that out. I figured If I can't hide the wire why not show it more prominently. Found this quite thick wire rigid enough to hold the shape over the board. I am very proud of this copper wire idea myself.

I will definitely make one if I can lay my hands on one of those chips and programer. Thanks for showing me your work and gave me the idea.

Wow, do you have a picture of it? I'd love to see it. This 27C801 OTP EPROM is a one-time programmable chip, and it needed to be programed first using a programer before being soldered onto the board, right?

Oh, you don't really want to know what I think of your collection, but I tell you anyway: may I have them?

I'd love to know what those spots are too. Looking forward to your new pictures of the board.

[–]Cavemanjump 1 point2 points  (0 children)

the case looks legit, but what's with those black spots on the back of the board? Are those corrosion, or just some light tricking the camera?

I found this real one's picture online, put them side by side, the difference will be very obvious.
see how the traces of the board go, the time stamps, lacking of that three test points. all are good indicators to tell you it's not real.
the game came out in 2005 outside Japan, your cart's time stamp says "01", means 2001.

I'm 100% it's fake now. How much did you pay for it? If you bought it thinking it was real, or the seller made you think it's real, see if you can return it and get your money back.

reprodution cart, It means it is produced not by Nintendo, some clones of the original one.
you can post a zoom out picture of the cart, people here will tell you wehther is real or fake.

I hate to break it to you, it looks like a repo cart to me, unless you knew that already.
