Everyone was telling me they wanted the 8 Mbit version.  Is everyone willing
to go with the 4?

Yes, I knew about that code, forgot to mention it in my previous email.
Ironically though, most of the info you can extract from it is about the
f2a usb cable, not about the flashing process itself. From what I've seen
they just use the f2afirm.hex code from the windows utility provided with
the cable, but they don't provide the source for that GBA code
(though reversing the interesting part shouldn't be that hard).

A PC file-server for the GBA, whether through serial or USB
(provided you have the code to drive the USB cable) can't
be that hard to write from scratch ?

I still think an USB linker would be a better choice because you
would have the certainty of being able to flash the card, and the
possibility of file-serving with a bit of work, much of which has
already been done in if2a.

With the MBV2 you'd have multiboot and file-serving out of the box,
but the ability to flash the card remains theoretical.

In the end it all depends on which feature is more important to you,
I guess.

I'de be very interested to hear about what you are doing. For myself,
I'd like to try driving the USB cable from a PC program to communicate
with the GBA (file-serving and more) so I'm always keen on following
what others have done in this domain.

Could you please keep me in touch if you make any progress ?

ok. so then was the bulk-order going to be 8-mbit sticks or 4 ?
it seems that due to the problems with 8-mbit then 4 is the way to go.
unless no one is interested in the 4-mbit version.

hi,

thanks alot john, you've really helped my understanding of the flashing
process of these carts.

i found some f2a flashing code (for linux) from http://deyv.free.fr/gba/f2a
with source included. i think i'm going to take a risk and assume i can
port that source to write through a serial interface, making the mbv2+f2a
combo a full solution. i'd go so far as to say it might even simplify the
code, as writing through a serial port is probably easier than through
usb, but i'll have to investigate further.

the reason i'm so hung on the mbv2 is that it has some good pc
file-serving code already written for linux. unless there exists such a
thing for the f2a linker (must be for linux, or have the source available
for me to port) it seems easier for me to use jeff's mbv2 file serving
code.

i don't have any of the hardware yet, so i won't be starting for some
time, but if anyone's interested i can post this when i'm done.

regards,
-mike.

You're right. It looks like the MBV2 is not as flexible as the f2a usb
linker cable - apparently it would need a new firmware to
flash newer cards.

The problem is that the MBV2 does not offer a simple way for a GBA
program to communicate directly with the PC (there's a serial interface
but you need another cable).

The F2A cards are writable from the GBA, this means any program
that runs on the GBA can just flash the cartridge. Uploading such
a program to the GBA is very easy to do with the multiboot facility.
All that remains is for the uploaded code to receive the contents of
the cart from the PC - this data obviously can't all be transferred during
multiboot since the RAM is only 256KB.

This is exactly how the f2a/usb cable works : they send a little bit of
code through multiboot, which starts and listens for data from the PC.
The PC sends the cart data to the GBA, probably in UART mode,
and the code on the GBA writes that data to the cart.

So in theory, assuming you had connected your MBV2 to your PC's
serial port in addition to the parallel port, you could write that bit
of GBA code and the controlling program on the PC, and everything
would work just fine. I don't know of anybody who has done that, though.

But I think you should rather buy the f2a/usb cable, as its price is
negligible compared to the price of the flash card anyway. And it can
do everything the MBV2 can, and more.

hmm. how hard would it be to do this? ie. is there software around to do
this, or am i looking at writing/porting code to do this myself?

sorry for all the seemingly pointless questions..just trying to figure out
the best solution for me without spending/wasting too much money.

Im looking if have any 3D render for GBA? something like OpenGL or D3D...
Any links? I know that Yeti3D has port to GBA, but dont know how it was
made...

Thanks

Where did you read that one couldn't program an f2a through
the mbv2 ? In any case, it is not the cable (either the mbv or
the flash advance linker) that programs the cart, it is the small
amount of code that is uploaded on the GBA that does the writing,
so there is no reason that you couldn't upload the appropriate
code using the mbv2.

What is the pricing for them again?  I would be willing to buy 4 or 5
of them, depending on the price.

Isn't the F2A backwards compatible with the FA?
Pogoshell should work correctly on both I think.

hi,

does anyone know where i can buy one of the original flash advance carts?
all anyone seems to carry these days is ezf, flash2advance, etc.

i would like the older flash advance cart because it seems like it will be
a good gba-dev solution along with the mbv2. my primary dev machine runs
linux exclusively, so i need to be able to flash it from linux.

the mbv2+flash advance combo appeals to me also because it can be flashed
without removing the cart. on the whole it seems like a pretty good setup.

is there a better solution i should be looking at?

Thank you for all you effort in this!!!!!!!
I look foward to being able to print my own mini-demos and games on paper.

All I have is a Hp 750 with a 600 dpi max (though only 300 is offerend in
the printer properties), I guess I will have to get another printer.  When I
try to print I always get a dot code that is way ot large..

Thanks  again!

With a little bit of luck you can print dot codes on a (nowadays) standard
inkjet printer. The "lowest" I could go on my printer for an acceptable
result was 600 DPI and high quality inkjet paper. For best results, use 1200
DPI and photo paper. Make sure the dot code is printed using my tool at the
correct size, which is a little bit larger than a real dot code. The dot
code will be printed at the bottom of the page, ready to be swiped through
the e-reader.

So far working results have been produced on a HP DeskJet 3650 and an Epson
Stylus C85.

What is the correct way to print these dot codes? Will a normal inkjet print

Just to let everyone know that the Reed Solomon error correction used by the
Nintendo e-Reader has been finally figured out. You can download the first
custom created set of dot codes for the NES game called "BombSweeper" by
SnowBro from http://users.skynet.be/firefly/gba/

In the next few weeks I am probably going to write several Z80 based
e-reader mini-games and release the source code so that anyone who is
interested can write his/her own mini-games too.

There are several map editors in this list
http://www.gbadev.org/tools.php?section=gfx not all work as good but they
are worth checking out.

Do I need to create a map editer for a rpg game?as I know ,to program a map
editer is a very difficult thing.
   Can I use a map editer that created by others?

i needed to generate an interrupt when a certain condition in my program is
reached, i wanted to fake an interrupt.

what i ended up doing is moving to irq mode and calling the regular interrupt
handler at 0x018. to the interrupt handler it looks indentical to a real
interrupt.

thanks everyone for their input about this.

recent updates include binutils 2.15.90, newlib 1.12.0 and finally, a win32
native build of Insight 5.2.1. I've also added the SDL version of Visualboy
Advance to the downloads section. This is the one you need to work with
Insight.

There is also a fairly complete set of headers included in libgba and a
small example project including a relatively generic makefile in the example
code section.

I've got a shorter url for the homepage too at http://www.devkit.tk if that
doesn't work for you, the page is still accessible through
http://homepage.ntlworld.com/wintermute2002/

Anyone yet? The big N seems awefully unfriendly to non-
"professionals". Personally, I think it doesn't matter as long as you
could produce a good game.

Thanks!

Hi,

I get the message "Stick init failed" with a 8Mb Memory Stick.

Does anybody succeed in using Libstick on 8Mb Memory Stick ?

I would appreciate to get a tested
"smsflash+mbencryted_demo_program".gba in order to try it on my Memory
Stick.

Regards.

Thierry
