World: r3wp

2 bugs found: poke doesn't work with tuples and when we poke an image 
with a  RGB tuple value , RGB channels are mixed in a strange manner.

new version of  galaga.r http://perso.orange.fr/rebol/galaga.r

use rebcode but not for the video emulation, so we can get it faster, 
soon...

only 86kb for the source + game rom

(game rom include)

this demo is the first stone of the future MSX emulator, but we could 
emulate lot of computer based on Z80 ship.

the next step is to  include the PSG emulation, yeah ! we will have 
music too.

hey, what about a 6502 emulator ??

Impressive, Steeve.

wow, that's great, Steeve!

I am getting some error - which is the latest rebcode release?

works in rebview13611031.exe here

ok, thanks ...

sorry, 1361031 it is

yes, well, that is so cool :-)

although I wonder if rebol can be fast enough - still sluggish ....

it probably can, if rebcode is allowed to write straight to a display 
buffer rather than through View.

ah ... hmm, we will see what new View comes up with ...

there are also some time wasting color conversion going on. if that 
could be done in 1-2 ops, it would be much faster.

but it shows nice potential, doesn't it? Especially if something 
like ZX Specturum could be emulated :-)

yes, definitely

steeve, you could probably make your file even smaller by enbasing 
the game rom in source.

i removed some debug instructions, it's a little more faster now. 
Don't forget i have to rewrite the video emulation too. So it will 
be definitivly faster (i hope).

hmm, but nice anyway ... Steeve - if you find anything what could 
improve rebcode, discuss it with Brian eventually and put it in RAMBO 
:-)

Pekr, do you really think it's sluggish? For me it's too fast to 
play even in the zoomed version:]

I ran it through remote desktop on Windows via OSX. speed was a little 
slow, but ok

Bravo Steeve.

ah merci

bon faut que j'aille au boulot moi

co to? :-)

Babel: bon faut que j'aille au boulot moi = good is necessary that 
I go to the job me :]

probably not the best translation

Human: Well, I need to go to work.

speed improvement of http://perso.orange.fr/rebol/galaga.r

all video routines have been translated into rebcode, but it' s not 
so fast than in my dreams.

- Added a button to switch Draw randering between bilinear and nearest

*as in my dreams ?

Getting better. :)

yeah and now u can try i with sound (same adress)

some problems to recogniez the original music

argh !!!

*recognize

i must add a trick to negociate the good frame rate

warning: sound port is really buggy and destroys your samples over 
time.

I don't think the current sound-port implementation is worth bothering 
with.

hmm... maybe you can maintain the fidelity of your samples by inserting 
copies of your original samples.

yep, i fear that

I had success with external library interface and FMOD audio library, 
but it's not cross-platform (or open source).

The good work is to find a nice little open-source audio library 
for playing samples and try to integrate it into rebol.

i think if i let the sound like that, RT peoples  will have a headhash 
and will implement a correct sound port  soon.

so , i will add a mute button

I forget, has OpenAL been ported to Windows yet? Perhaps that will 
work, Anton.
