Indeed, you can have upto 2048 tiles, if you don't use any of the RAM for anything else, but certainly several hundred to a thousand or so tiles is totally possible, and does indeed have great potential for games and the like. Also for mixed text/graphics programs, like a web browser, where the text can be reusing the character cells as normal (they can still be mono), and then the higher number character IDs point to graphics blocks, allowing mixed text + 256 colour graphics.<br /><br />As for what is coming next, even I don't know. We will have to wait and see what Daniel cooks up, but I suspect you might be on the right track.<br /><br />Paul.Paul Gardner-Stephenhttps://www.blogger.com/profile/10150903760695355706noreply@blogger.comtag:blogger.com,1999:blog-4017745189504803687.post-68809190710818950442018-01-31T20:40:04.402+10:302018-01-31T20:40:04.402+10:30Reading the story a second time, I think the most ...Reading the story a second time, I think the most important technical demonstration here is that everything is done in text mode. Therefore, this is not just a demnonstration of capapabilities to display static pictures, but also how good the graphics can look in real games, i.e. platform games.<br /><br />The ability to do 800 different tiles is really great and will have a large effect on the graphical versatility in games.<br /><br />So for the guess what is coming next: A large area scrolling graphical demo.Daniël Mantionehttps://www.blogger.com/profile/07865411495348454676noreply@blogger.comtag:blogger.com,1999:blog-4017745189504803687.post-24097982775260819902018-01-31T19:39:22.820+10:302018-01-31T19:39:22.820+10:30Very impressive :)Very impressive :)Gurcehttps://www.blogger.com/profile/02581084898137756342noreply@blogger.comtag:blogger.com,1999:blog-4017745189504803687.post-90049086332349465032018-01-31T18:47:19.013+10:302018-01-31T18:47:19.013+10:30Yes, very impressive demonstration of the graphica...Yes, very impressive demonstration of the graphical capabilities.

I had quite a few situations where the result in GIMP was, well, acceptable, but when switching to the command line and redoing the quantization with Neuquant there was a enormous difference.<br /><br />The algorithm in Gimp is good if you do dithering, but produces colour bands if you do gradients. I see colour bands in the shadow of the legs of the lady and in the blue ocean. Neuqant may do a better job there.Daniël Mantionehttps://www.blogger.com/profile/07865411495348454676noreply@blogger.comtag:blogger.com,1999:blog-4017745189504803687.post-10454546063277689372018-01-31T11:48:31.734+10:302018-01-31T11:48:31.734+10:30Amazing !
