  1. Dreamcast Atari 800 emulator with large collection of games, sound and graphic demos and Atari 5200 games as well.Emulator has DC keyboard support but one is not needed as it also has a virtual keyboard function.Tested and burned with Imgburn for Windows. This is a self booting disc. This is a new collection of games and demos I put together in December of 2013 so it is a new collection for the Dreamcast as of late in 2013.

  2. OK - as promised, here are the results (not as good as I had hoped). The image on the left, is using no dither, 1000 solutions, 45 million iterations and an image mask of my entire car. This made the red car above it have too little detail. The image on the right is also no dither, 1000 solutions, 63 million iterations, and no image mask. Before running Rasta Convertor, I trimmed the image in Photoshop, converted it to a 256-colour image using the Altirra.act palette, and applied a 75% diffusion dither to the image.

    You need to let Dither run in the rasta proram, it makes a huge difference I have found. The Knoll method is slower but gives much better results. The car photo you converted is nice though.

  3. Lots of great images here but some are horribly stretched. Like the Tolkien picture. It would be cool if he were not squashed. Philsan's images look good. Maybe he could post a tip for the others on correcting aspect ratio.

     

    That was my fault. I did a resize of the pictur before processing and did not keep the correct aspect ratio.

  4. The wolf is amazing! How long are these images taking to convert?

     

    Using Knoll dithering, 10000 or more solutions, I try different pallets until I get one that looks good on destination screen I let them run for 100 million to 200 million cycles which can take 8 to 12 or more hours depending on the picture. I let it run, minimize it and kind of forget it's there for hours at a time.

  5. RastaConverter executables are not only raw data but the main part is the raster program that shows the data. The program is generated for each picture separately.

     

    Thank you and thanks for all your great work and pictures you have shared here. Do you happen to have a link to a document explaining how the details mask function works?

  6. How does details mask work and how would I generate a details mask from a picture to use in the Rasta Converter. I poked around the Rasta FAQ and Forum Posts but still did not find the answer to this question so decided it was best to ask.

     

    BTW all the pictures are really great. I love this tool and have been playing with it for a long time now and still enjoying it.

     

    I forgot to ask if there is a utility that will let me extract the raw picture file from the.xex files? Would they extract to a known atari picture format so that i could use one of the many picture viewers with slide show function?

     

    thank you
