Re: MOON ADVENTURE

I've developed a really good technique for extracting the differences between images and only recording that changed data (so the packing is more efficient). The previous packed images for the Asteroid GIF resulted in a 28.5K tape file. @ECHO OFF :: Full Screen Asteroid2 :: Enable variable changes w...

Re: MOON ADVENTURE

If you get Imagemagick to do the dithering (instead of pictconv) you get many more options, sometimes better quality and sometimes smaller images (especially after packing) SET IMAGEPATH=VIDEO\ASTEROID2\ :: For Main Program :: Full Screen Asteroid2 DEL %IMAGEPATH%\*.PNG ::convert %IMAGEPATH%\ASTEROI...

Re: MOON ADVENTURE

ASTEROID2

Some GIFS use transparent frames which screw everything up so use the -coalesce function in imagemagick

e.g.
convert ASTEROID2.gif -resize 198x135 -coalesce ASTEROID2%02d.PNG

Re: MOON ADVENTURE

Try these: The next two "videos" have been extracted from animated GIF's. They are not very fast as they are running at quite high resolution (the Star Wars shuttle craft is the biggest at a resolution of 198 x 147). The Asteroid is 120x120. To extract images (in order) from your selected GIF and pe...

Re: MIDI play for Oric.

Hmm thanks. I also observed that .AY format files could also be easily converted to .YM with AY emulator program. This enlarges the music database that can be transferred to Oric. Just an example :) First I converted prince of persia music from .AY to .YM. Then to MYM etc.. http://www.youtube.com/w...

Re: MOON ADVENTURE

yay...got the unpacking correct. I must admit I was struggling earlier and I nearly fired a distress flare. The unpacking adds a slight overhead as each chunk of 6 frames gets unpacked. It's noticeable but not a show stopper. It might be an issue where each frame is one file (rather than 6 frames pe...

Re: How to load a software from a menu with sedoric

Try a short BASIC program to do something like:

1. GAME1
2. GAME2
3. GAME3 etc

PRESS Number to LOAD

On your disk you would have a game1.com, game2.com etc

if (x=1) !GAME1.COM
if (x=2) !GAME2.COM

something like that

Re: MOON ADVENTURE

If you are serious about doing pseudo-video on the Oric, I think you should consider some alternative ideas: - You could refresh only every second line, using some color changes to simulate the screen persistence like we did in the Assembly 2002 invitation intro: http://www.youtube.com/watch?v=Efeg...

Re: MOON ADVENTURE

The FilePack unpack routine in 6502 assembler is already in the osdk, you don't have to use the C version. Now yes, it will not work with a 'width offset' simply because that would make the code extremely complex: Just use a temporary unpack buffer and copy it to screen. I have a cunning plan...a w...

Re: MOON ADVENTURE

@iss Thanks, you've probably solved a separate problem that I had and I'm definitely going to make use of that technique. Imagine a space suit scene, I want to use the same spacesuit, overlaid on different backgrounds, with different faces shown through the visor (all chattering away at the same tim...

Re: MOON ADVENTURE

OK, what I really need now is a flexible unpacker routine. In the example below, the "looking right" sequence is represented by one file (seperated by Oric software into 6 frames of 72 pixels (12 bytes) by 48 lines.) look-right.png As an unpacked image everything is peachy and the following line gen...
