GBA Jpeg Viewer
GBA Jpeg Viewer is a tool to display Jpeg pictures
on your Gameboy Advance(tm) (both normal and SP version).
and also the Gamecube via the Gameboy Player and now the Nintendo
DS (via the GBA Cartridge slot)..
Q1) The rom generated by your program does not
work in the real gameboy, only in an emulator.
A1) It's because the rom lacks all the standard copyright
and crc infos of Nintendo, and so it's not recognized by GBA
as a valid rom, you should use a loader or the pogoshell.
Q2) Why don't you include all the nintendo copyright and
crc stuff in your rom header?
A2) Why don't you use pogoshell?
A3) I don't know anything about nintendo's copyright issues
and i don't want to get into.
Q4) I like the new 432x288 zoomable pictures feature, why
don't you allow bigger pictures to be stored?
A4) This is a frequently asked feature, but it's really hard
to achieve because of the memory limitations. of the GBA.
A 432x288 picture can be decompressed in the 256 Kbytes memory
of the GBA and then zoomed or scrolled, while a bigger picture
Q5) But the XYZ viewer DOES it!
A5) It's because XYZ uses uncompressed pictures. To scroll
a picture this must be uncompressed somewhere in RAM or ROM:
if the picture is present in ROM in an uncompressed form there's
no problem in blitting a part of it in the GBA display so
that you can achieve a scrolling feature, but if the picture
is stored in a compressed form (like jpeg) you must unpack
it in RAM before scrolling it. Since GBA ram is really limited
I can't unpack pictures bigger than 432x288.
Q6) So... could you store uncompressed pictures in rom instead
of using jpeg?
A6) It's GBA Jpeg Viewer, not GBA BMP Viewer!
Q7) I use your software to store Hulk pictures in my GBA
(as everybody should), so that I can satisfy my hulkamania(tm)
needs wherever I like, but I've tons of funny Hulk videos
as well: what can I do to view videos on my GBA?
A7) I'm working on a video encoder for GBA: the project includes
a free limited GBA Jpeg Viewer like tool ("GBA movie
player"? "GBA video player"? ... name suggestions
are welcome) and a commercial library to bring video to other
GBA game/applications. More to come soon, stay tuned. By the
way, if you really can't wait to see Hulk moving on your LCD,
you can visit my GBA video page
Q8) Is your program really free?
A8) Yes, because I've had a really good time coding it as
you are having using it and I think I shouldn't be payed just
because I've had some fun!
By the way some people are not so lucky and they cannot code
nor play with a GBA: if you are really happy with my software
and you think it worths, please visit www.christopherreeve.org
