it would be strange for a battery to go flat that quickly, but then it could just have been a bad battery

Damn, after less than a year?
I'll see about getting a replacement - this is the good point about getting an EMS one with the no soldering and whatnot, haha.
Thanks for your help, this had better sort it! D:

both could cause problems but the battery in the cart is for saves, so its probably the cart battery

Cart battery or DMG?
I'll switch round the DMG ones tonight, though the screen isn't dim or anything like it usually does when it's low on batteries

maybe your battery is going flat? if you are sure everything else is fine, then that has to be the answer, unless the ram chip is decaying

It's an EMS cart that I've had nearly a year now. I've never had any trouble before.
I haven't opened my DMG for months - ever since I installed my bivert chip like, 6 months ago or more.
Again, I've never had any trouble otherwise.
All other games work fine.

I'm convinced this must be a problem with the sav, or else my ArduinoBoy has fucked up both my DMGs somehow (I think I've only used it with one anyway...)
The cart has always been fine.
The ROM has always been fine.
The DMG, with everything else, is fine.
However, the save file randomly corrupted when I hadn't done anything, and gives me inexplicable problems.

It's just totally bizarre though

Sorry, button input, not keyboard input.

first of all, is it a bleep bloop cart? if you open the cart up some of them have bad pins on the ram chip, if you can get a high res pic of the ram chip that would help. i had a bleep bloop cart and one of the pins was bent on the chip so that it had missed the solder point, this caused it to work most of the time except sometimes it would glitch.

secondly, on the DMG the -18 supply for the screen is very close to the button inputs and if the ribbon cable is inserted badly while the gameboy is on, it CAN send 18v into the CPU which fries half the button matrix. but this is a permenent problem and effects all games.

if the problem is the same on the SP and the DMG then its not the gameboy, its the rom or the cart, if you can try another cart, or if all people who have this problem can post what cart they are using it might point to which is at fault

Keyboard input?

My gameboy was fine for months - it hasn't been open in a long long time. The problems do seem to coincide with me getting my ArduioBoy, but I'm not sure how that would do this as the problem occurs when the ArduinoBoy isn't connected as well as when it is.
The save did have like, 17 songs on though. I deleted some, though apparently they don't always fully delete? Not sure if that could have something to do with it, just trying to think of all the possibilities.
Thanks man, I appreciate it

I had/have a similar problem on a 'boy that someone asked me to fix. I just replaced the innards and kept the broken boards for myself for future analysis. Perhaps I'll be able to figure it out one day.
It might be that the keyboard input is half-broken because the -18V power supply line for the LCD touched one of the lines related to joypad input. NeX, care to comment?

Oh that was your mail... Didn't realize. Yeah, I'll take a look at it.

I never have the problem with any other game, and it happens on multiple gameboys. No way is it a short like that. Also, it only happens every once in a while.
Did you get my e-mail?
And yeah, I need this sav fixed pretty desperately

I actually think the original problem is a problem with the buttons of the Gameboy. Ie, a short circuit between the buttons.

Do you mean to get the sav fixed?

Yeah, so I turned on my DMG today, and my cart crashed...
I finally got it to display something other than a blank screen, and it was filled with 00's and 39's.
However, as this was actually during an audition for my school's rock night, I had to play, so tried loading up songs. It worked fine, but very clearly something is fucked with my save.

Is there anyone I can send it to and get it sorted? I have a backup of the save from before it crashed, but considering I didn't turn it off when it was playing or whatever, the problem already existed (hence the freezing).

My machine is a like 10 year old dell, and has no problems.
I've backed up my save, and ROM - that isn't the problem.
I was wondering what would happen if I used the sav with a ROM without the kit patched in, and what would happen to the songs that use it.

However, I'd really love this to be sorted. I don't think it's the flashing software as I have never had a problem with it...

if you are on 64bit machines, you've got to be in test mode and have digitally signed the drivers through the DSEO software... 

on 32bit machines, or 64bit, for that matter...  if the install doesn't go right, or something is malfunctioning, go to 'devices and printers'.  if the cart is plugged in and working right, it will appear as funtional here.  if there is anything wrong with the driver install, you'll get an error in this section.  don't bother troubleshooting it or auto-fixing anything....  its all got the be done by hand.

so, first is to uninstall the drivers from the device.  unplug the cart and everything.  then, open dseo and go into test mode (if you already aren't).  and, restart your comp.  next, digitally sign the files you need.  and, again, restart your comp.  then, plug in the cart and do the manual install.

my first install of the drivers went pretty smoothly after i got off my dell XPS (these machines, 400 series dell's in general, have issues running some drivers it seems).  but, i deleted my files accidently, and the reinstall i had to do a couple times.  same procedure each time.  but, it only worked after the third try about.  and, i haven't had issues at all since.
