Hello, my name Rony

I'm a final grade electrical engineering student of Satya Wacana Christian
University, Salatiga, Indonesia, and i'm just new in GBA Dev. world
I want to learn how GBA cart work, how to make it programmed,
and how to program it, and i'm intend to make it, so ...

Could anybody send me the schematic for the GBA Game cart and The programmer. I
need the GBA programmer that which is using only a Flash ROM and some logic
gates. (Because i don't know how to using a CPLD or EPLD, and i don't have it
one)

I'll be so gratefull if anybody also mention or send me the programming software
for it.

Regards,
Rony

Yosuf,

Yes, I am very interested!
I have created an outline for the pcb, but I have never had a GBA
board in my hands, so I am not sure if it will work. I do have the
GBA, but no cartridge. I bought it just for this project.

best regards,
Vital

If you are interested, I can send the physical gerber layer for a
board I developed to run on a GBC, but later modified for GBA.  The
board is 0.1 inch thick and is not inserted in a plastic case.
Instead, there a plastic cover mounted on the board, thereby avoiding
the cost of a plastic enclosure.  I have added a pair of "fingers" on
each side of the board to trip the GBA microswitch to place it in GBC
compatibility mode.  These fingers will not be needed for a native
GBA board.  You can see photos at www.databoy.netfirms.com.
Note: I developed my PCB using the free version of the Eagle layout
editor (www.cadsoft.de).

Hi!

I did mean thinner.  Admittedly we were using a 6 layer board as I
recall (4 signal, 2 power/gnd) -- so it had to be thinner than what
we use for our other boards..

Kurt,

You meant "thinner" or "thicker"? I did a test using a generic board
(1.8mm thick) and I had to put two business cards behind it to have
it correctly pressing the GBA contacts. The total thickness (board +

What about the cartridge shell?  If you open a real cartridge, you'll
find the board is thinner than most blank PCBs.  (At least the two-sided
ones I get at RadioShack...)

Of course, you could make yours a bit wider than a normal in-shell one
and have one that doesn't require a shell.

When you go to fab your board remember the board "thickness" is important.
As I recall the GBA Cart board (at least for the connector) is thinner

Indeed, you'll need to build it. It would be nice if the various
flashrom usb programmers
could double as serial ports.

I recently built a USB<->GBA cable based on Darkfader's design. I
also built a little
program to communicate between Macromedia Director <> GBA which is
buggy but will
get you there. I'll be rewriting the communication protocol in the
next couple of months using interrupts, probably when I've finished with the
MIDI project.

You can follow this link at:

http://hypermedia.loeil.org/playmobile/user/douglas/

and scroll down to the entry "usb+ttl+gba" where you'll find an image
of this project. Instead of going serial <> max232 <> GBA, I decided
to use the
well-known FTDI USB<>TTL chip.

There are lots of links and some code (cf. "download"). Its all in
French, but you should be
able to figure it out. Drop me a line if you're lost.

You can see the one I just made if you follow
the link at the bottom of this page:

http://www.msh-tools.com/GBA/gbagps.html

there you will see my very rough assembly,
including the embedded antenna (to Hari Nair:
that's what they call it - it's an antenna you
can embed!).

I turned it into a more successful project
by using my old original GBA, which doesn't
mask the module.

Unfortunately I can't help on the buying
side. I just phoned the local distributor
here in the uk and I had it next day.

Please let me know how it works out - I have used the SQ module
externally connected to the link port in uart mode with the trimble
compact patch antenna. I found that I could not get an initial fix on
moving cold start. It took several minutes for initial fix on
stationary cold start, and after that was Ok. I did not implement warm
start functionality, so do not know how that improves the situation.

check out www.pixelproc.net - gives idea of the rough dimensions of the
sq module and the patch antenna relative to the GBA SP dimensions

Hari

Yes. I was hestitating over this. I was aiming
for a really-simply-system®, so that people off
the web could just hack open a midi cable and
plug it into the GBA without a PIC. But even with
a couple of resistors and whatnot we're already
talking about soldering, i.e. for
people-in-the-know, so I might as well go with a
PIC solution: cleaner, easier to program (just
use the 38400 UART mode and let the PIC do all
the work).

Yes. I was just going through the skimpy docs
on-line on interrupts just for this purpose. I
think I've got it down now.

Not everyone has access to some sort of external
programmable circuit. I'll see with my time-frame
what's the easiest. Thanx for the info.

Thanks for the information. I will use the Lassen iQ module, that
consumes a little less power than the SQ and will use an external
antenna. I was looking for a module with an integrated antenna but,
as you told, the metal shield would cause problems. Anyway, I would
need an external antenna for use in vehicles.

The Lassen iQ seens to be easy to buy samples.
The only thing that would be better than the Lassen iQ would be a
module with a SPI interface. It would save me of implementing an UART
in my CPLD.

thank you

There are a few things that will need to be addressed when connecting a midi
system to the GBA...
The first issue I see is the voltage difference - midi is a 5V interface
whereas the GBA comm system is 3V.  While this isn't necessarily a problem
(as the nocash xboot cable works fine), it could potentially hurt the GBA's
comm system.
As far as whether the communications should be handled in software or
hardware, the only difference is what kind of a challenge the implementation
is.  An external hardware system that buffers and retransmits data is
relatively simple to create, and much less of a pain to code for. It is also
possible to do the communicaitions on the gba itself. When in general
purpose comms mode, the GBA can be instructed to interrupt when SI
transitions from high to low, which will detect the beginning of an incoming
UART transmission.  After that, at 31250bps, the gba has approximately 537
cycles per bit to deal with incoming data, so many means of collecting the
data (timer interrupts, or just wait loops) could be used.

In my opinion it doesn't really make much difference whether the
transmission and receiving is done in hardware or software... hardware has
the potential to be a bit more stable, but software won't require as much
external work.

I'm trying to get MIDI into the GBA through the
serial interface. I've done lots of experimenting
with this serial port (cf.
http://hypermedia.loeil.org/playmobile/user/douglas/)
but getting MIDI in looks like it's going to be a
little uncomfortable. Has anyone already done
this? (I already know of all the GBC MIDI
projects -- pushpin & firestarter -- I'm
interested in a GBA-specific solution).

The main problem is that MIDI working at 31250
baud whereas the GBA supports only 9600, 38400,
57600, and 115200.

I was thinking of using the serial port in
General-Purpose mode, and trying to figure out
all the timing. This is cleaner than building a

really have any experience with General-Purpose
so I wanted to get someone's (anyone's?) opinion
on this matter before getting my hands dirty.

I'm trying to get MIDI into the GBA through the
serial interface. I've done lots of experimenting
with this serial port (cf.
http://hypermedia.loeil.org/playmobile/user/douglas/)
but getting MIDI in looks like it's going to be a
little uncomfortable. Has anyone already done
this? (I already know of all the GBC MIDI
projects -- pushpin & firestarter -- I'm
interested in a GBA-specific solution).

The main problem is that MIDI working at 31250
baud whereas the GBA supports only 9600, 38400,
57600, and 115200.

The Trimble Lassen SQ (or newer IQ model) does not have an embedded
antenna. Check it out (www.google.com)  :-)

Hey, has anybody done any RTC programming with an EFA cart?  If so how
and what did you do? Does anybody out there know where I could get
some info on this? EFA's website has no info.  If I want to get the
RTC data from a memaddress, does it even matter which cart I use, do
various flash carts have this in different places or same places?

Any info would be great, Thanks!

The only way to get to use one without having official developer status is
join a Nintendo approved games programmning course as far as I'm aware..
