yea i am still selling midi kits you are welcome to drop me an email smile Ralph (dot) nex (at) gmail (dot) com

do it, its loads of fun, i had two gameboys synced and one was pitch bent, by changing the pictch just changes the key of the music without it going out of time.

the only problem is if you drop the CPU speed too much then it doesn't run fast enough to process the sync data properly, and then it starts to go out of time a bit

@ Nex.

Oh wow. hmm That's very disappointing...
Well I'm guessing you have another project set in mode! haha
Can't wait for the next! big_smile

i have plenty of projects but no time really. i will get this RGB boy up and running and probably do an update post with some of the new mods, just really cant be bothered with it at the moment.

Awh damn I figured such. hmm
Thank you for the reply!
I'm looking for a safe way to place the RGB LEDs around
the same area you did, but you managed to get all of those wires in
that case without crunching/bending?! I congratulate you! That's
def a lot of skill with 3-dimensional placement like others have
already said! O_O

I struggled getting my wires placed right with just my PS mod. hahaha

thanks! ironicly this gameboy isn't working any more, i opened it up to install some new stuff inside and now the CPU keeps crashing, i have put it to one side until i can be bothered to fix it again.

Nex, where did you solder the LED wires? :<
If you don't mind tellin', that is! smile

all the LEDs are wired to the arduino

GBA SP Stock:

GBA SP Prosound:

I know this is old but I guess I missed this thread...

The prosound shape is different because the lack of a CAP. Also though the stock sp the cap looks to be a little extreme- so maybe just changing out the cap with a different (higher?) value would give close to the same results.

I don't know how much you know about this stuff Trash80, but please don't take it as an insult if i go into detail, its more for the benifit of others. the SP has a single cap, and it is there to create an AC voltage. the SP doesn't create a negative voltage, so it creates a mid way point using a cap. the bigger the cap the better bass response in theory. the DMG has two caps, one on the left channel and one on the right, they are down on the small board on the headphone jack, again they are there to create a mid point so the voltage can go to a virtual minus. but this is not what you want for a line level recording, as you want the raw DC output. the caps on gameboys can be cheap and old and effect the sound. but in this case of the pro sound SP the cap is still in place on the other side.

but this is only for the SPs with the older amplifier, the more modern AGS101 boards give a very nice and clear sound when pro sounded, very close to what the DMG can do, except with the sp slightly distorting wave sounds which is a problem with the CPU itself.

Define "a little bit"...

I might be interested in this.  My brother has wanted me to prosound his SP for a while.  If you made a revised tut I'd be willing to give it a shot.  I'm not interested in keeping the speaker either...

btw i have done a much better pro sound for the SP but it can only be done on the more modern AGS101 boards because of the revision of the amplifier, it can also be done without SMD components, there is enough room for normal sized components. i have made a few for other people and they seem very pleased with them, but in the end its down to personal taste

I never tried the Pixelh8 MusicTech software. Is any reason for it not working on my EMS cartridge?

i got the same problem on my bleep bloop carts, i don't know how you are supposed to use the rom when it wont go on a flash cart

great work nitro as usual!

The super gamboy runs at a different speed then a gameboy. the tones are slightly higher. The tones will be out of pitch. wont they?

if you want you can just put a DMG crystal in the super gameboy. the super gameboy is out of pitch because it takes the 20 something Mhz crystal from the Snes and steps it down to 4. something, but it doesn't do it very well.

just a note that might be interesting.

first of all it seems like the japanese super gameboy 2 works in a european snes without modifcation to the lock out chip (i did the mod first on a switch before trying the cart, only to find it works regardless of the switch possition)

the super gameboy 2 is based on the gameboy pocket, i have actually put the CPU from a SGB2 into a pocket to make a silent quick boot pocket.

it is possible to put a normal gameboy CPU back into a super gameboy, and then booting it using a special cart (nitro2k came up with some code which will get the super gameboy to boot with a DMG chip, then you can just switch the carts after)

not only is it possible to put a link port in a super gameboy (in fact its very easy) but you can go as far to install an arduinoboy inside one, i have done this on my super gameboy 2, and on my gamecube adapter.

lastly, a small idea. the super gameboy 2 has a small transistor which switches on an LED when you are using the link port, it might be kinda cool to have a similar transistor in a normal gameboy

Damn, after less than a year? sad
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:

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

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