My engine splits the screen in two (could be more) parts, by changing
the char base register in a VCounter interrupt. That way I get
256 tiles in the upper part of the screen and 256 in the lower. Combined
with (over)estimating what tiles actually are shown, I can display 400+
different tiles at least at the same time. A drawback is the use of a
VCounter interrupt - you have to make sure you don't have a DMA going when the
interrupt is about to happen...

I use tables (not too big) for estimating what tiles are visible on the
screen atm. This is quite fast (about 10 scanlines/frame, C code) and
works nicely, but if anyone has a better method, I'd be happy to know it :)

>Wonder how many billion driving games there are gonna be.

Hopefully not too many. There are other games that can be made using
a mode7 engine.

Damir,

I support your project as I'm also interested in writing sound and
music routines, but I have no time to help :-(
I spend all my sparetime learning arm asm, arm devkit and gba programming...

Good luck.

i totally agree.

the easiest way to start this up would be if one could get a core emulator for
the ARM processor and the GBA. i think its possible to get hold on a open
sourced GB 4channel player but is there a open sourced GBA emu? or is one of the
GBA emulator programmers willing to share their source code?

if one could get hold on that, the sound emu is the easy part (isnt it?).

That's what I thought - glossed over a lot of stuff, no mention of games
like Virtua Racing, Ridge Racer etc. which marked the transition from
sprites to polygons, but then maybe non-geeks wouldn't have understood.
Fascinating to learn that the guy who thought up Space Invaders was inspired
by Breakout to create a game where the "bricks" shoot back!

So why not use bitmap BG for rotation/scaling, instead of tiles?

It's not that difficult - surely!

I'd suggest setting the Y position >= 160 and < (- sprite-height), so you don't run into any sprites-per-line limitations.  The previous posters' suggestion to set  the 1st char for sprites to 0 is going to give you sprite-per-line problems, so that's not the greatest idea, IMHO.

Cheers

I've got a similar thing happening and I haven't bothered to look into why yet, but I strongly suspect that if you clear the OAM by setting it all to zero, whereas on DMG/CGB it would have meant the 8x8 tile at position 0 in OBJ RAM being displayed at X = -8, Y = -16 on the screen where you can't see it, on AGB it will cause it to be displayed at X = 0, Y = 0, so you can.  So probably you need to set the positions of unused OAM entries to somewhere where you can't see them, which is a bit of a pain in the arse.

Simply set the x,y coords for unused sprites to offscreen coords, or make

You probably haven't turned unused sprites off.

Usefully I don't have the value here for turning them off but you
should be able to dig it out of some doc or other, or a demo, or the

<Begin quote>
It's said though that you actually can use a NeoGeo pocket copier with the
GBA too, so it will play NeoGeo games on your GBA, NGP and GBA cartridges
are aroubt the same size, all you have to do is upload a little program
along with the game ROM to your NGP flash cartridge and you're off. Maybe
it's time to secture one of those NGP copiers? and who knows maybe someone
will write a program which will let you copy games using the NGP copier!

I remain very seceptical tyhat the GBA can be made to play NeoGeo games just
by trying to use the NGP copier and uploading an extra program.
In other words my bollox detector is working over time.

Hello GBADEV,
I was reading the front page of 64scener, and It said that you can fit a GBA
cart into a Neo Geo Pocket Colour Exchanger. and It would work if it had a
custom program written for it.
Please could somebody tell me if this is true, as I haven't got mine yet.

Hi,

you can change the stretch mode with GBA L/R buttons.
This is widely explained in the manual (u, you can't read japanese?.. :)

> haha... maybe they'll force all the GBA proggies to be open source  =P

Hehehe! And then, l33t modifications:
Super Tux Advance! F-Tux, and Kuru-Kuru-Tux!

Yep, that's it. Thank you!

I definitely should have read the instructions booklet - oh wait, it's
japanese :-P

  Are you aware that pressing L and R when running a GBC game switch
the game between having borders and being stretched to fill the
screen? It sounds like that is what is happening...

Hi all,

I got my GBA yesterday. I'm sure there's no need to tell you the games I've
seen so far look superb :) Anyway, while testing my homebrew games (for GBC)
on my new baby I noticed some strange things:

First, as someone already pointed out, the colors look awfully darkish...
but, what really puzzles me is the display screen *not being the same size*
everytime I run the game. Sometimes there's a black border sorrounding the
screen (which I think would be the right setting?) and sometimes the game
starts with the screen stretched out covering the entire display.

The funny thing is the screen also changed from "narrow" to "wide" while
running the game. :-o

Has anyone else noticed this behaviour? FYI, I'm using Bung carts and the
game I was testing performed very tricky and tightly sync'd operations each
HBL. Maybe this has something to do with it, don't know.

so, the project would be to make a GBA Soundchip EMU, nothing else (i think iki, julien and the rest of the EMU creators are doing a great job so i wouldnt mess with other emulation than sound ;)
 
anyone interested? ideas? comments?
