this is my ultimate midi gameboy, i dont think i will make another one like this just because it was so difficult to fit everything inside.

this gameboy is actually FOR SALE! i will be putting it on ebay tomorrow, but if someone wants to make an offer for it before then, then they can email me Ralph (dot) nex (at) gmail (dot) com

this is a special edition one, in the way that if someone had asked me to make it i would have turned them down because of the amount of work, i wont be making another gameboy to this level for sale because of the work, the only reason i am making this and selling it is because i am going on holiday in 2 weeks and need the cash badly so i will be selling this at a lower price than i would normally. get a bargin!

basically it has just about everything:

clear case with text removed
clear buttons
case lights/button lights
"strobe lights" on the back that flash with the music
PS/2 keyboard socket to make any old computer keyboard into an LSDJ keyboad
white backlight with bi invert for high contrast
brand new screen surround
full midi support
pitch bent with a "low crash rate" switch between normal and pitch bent
3.5mm pro sound
normal headphone jack intact and internal speaker
1/4" pro sound
modified arduino with purple BPM light

so yea you wanna see pics ok:

this is the LED that lights up the D pad

pitch bent pot, very tight fit

PS/2 socket

midi sockets fitted, mode button and 1/4" socket

strobe lights down the sides

pitch bent switch

modification to the shield to make room for the bivert chip

pitch bent chip fitted and bivert

first test

midi start with many resistors

pro sound wired

arduino in place, clear buttons and biverted backlight screen

wiring nightmare!

more wiring

case lights/strobes

keyboard test

lights1

lights2

lights3

lights4

yep, in theory, but fitting it into a cart is another matter, and also you have the issue of, for example the gameboy is saving, where it writes to SRAM, then its done so you turn of the gameboy, but it still has to write to the SD card, so you would need a battery to keep it running so it could finish reading and writing

That's exactly how the Supercard for GBA works.

to copy the save from the ram to the SD card you have to press L+R+SELECT+A and wait for a couple of seconds.

interesting, but yea it would have to be something like that, and something similar if you wanted the rom as well, like the gameboy boots up, then you have to wait for the rom to be copied over before it can carry on, or something like that. easier with USB really

nope it wouldn't work for a start the microSD card is not fast enough to be used as a flash chip, but there is a lot of other reasons why it wouldn't work anyway.

not to totally derail the thread but would it be possible to write something that loads from a micro, and then writes to it, like having a reader backup automatically or something?

i want this!!!!! :DDDDd that would be USEFULL is a shame the usb cart that expensive and like imposible to get around here...

Any way possible to do this with a DS flash cart?? but instead of USB use the microSD they use (similar to the R4) cuz i have one R4 eating dust. Sorry if this sound insane, but i dont know anything about hardward and chips! sad((

you can buy the USB carts from nonfinite, or ask on the forums thats how i got mine,

and as for your other question, nope it wouldn't work for a start the microSD card is not fast enough to be used as a flash chip, but there is a lot of other reasons why it wouldn't work anyway.

easiest option is to buy the flash chip and then use a programmer to program the camera rather than trying to fit the USB part

True, not that I'd call jose a real genius except in the most sarcastic sense of the word. Would you consider sharing the pinouts etc.?

if you look in some of the pics you can see my notes for the pin outs, so let me sort through them and convert them into something digital and i will post them up smile

Couldn't you just shove a USB transferer in there and not switch the rom chip? You can still read the .sav file and that's all you need for the pictures.

If that is the case I may have to give this a try if i get my hands on a spare gameboy camera.

yea if all i wanted was the saves, but i want to do stuff with the rom too. now i have a flash cart with a camera attached to it, like someone said possible video to sound options?

What is the device installed in the DMG?

This all seems very cool, but honestly I don't understand how the MIDI ports are being used in the video, other than making the LEDs blink in time. I get the feeling I'm missing a bunch of essential backstory.

DMG in the video yea?

that has an arduinoboy in it,

basically the arduinoboy converts the gameboy signals into midi signals and back again. so if you want your gameboy to play in time with your midi drum machine for example, then you can link them together with midi and they will be in sync.

at the moment i don't have any real midi devices (other than a cheap keyboard) to demonstrate the midi sync, so i just synced the two gameboys together.

all this is doing in the video is the same as a link cable and two copies of LSDJ, but with midi instread of gameboy serial. but the main point, is only gameboys understand gameboy serial and so can only sync with each other. millions of things understand midi and so the sync options for the gameboy become much more open, i can sync the gameboy with a computer, or a keyboard or anything with a midi port really.

Nice man.  You are very talented!  Tell us more about the prosound mod!  smile

i could do a guide for the pro sound, but people have to be confident wiring SMD parts, also it only works on the later AGS101 model
