JamesD Posted July 12, 2014 Share Posted July 12, 2014 Since someone has started going to the trouble of writing animation demos for the CoCo I thought a dedicated thread might be in order. No this isn't an Amiga. 6 Quote Link to comment Share on other sites More sharing options...
John_L Posted July 12, 2014 Share Posted July 12, 2014 Those above are courtesy Simon Jonassen, he's quite good, and has some amazing stuff... I think some of the most impressive stuff is the Donkey Kong transcode that John Kowalski did. He took the Z80 code from Donkey Kong and rewrote it in 6809 for the CoCo 3. The results are amazing considering the 6809 is doing all the work the Z80 did, plus handling sound generation as well. Another impressive bit of work was done by John Linville, another CoCo guru with lots of CoCo smarts has a working video player... 6 Quote Link to comment Share on other sites More sharing options...
remz Posted July 13, 2014 Share Posted July 13, 2014 And here are some demos made for a standard 128K CoCo 3 to show what this little machine could do: It could also 'simulate' the sound of a C64 SID: And lastly my most ambitious project: first-person realtime texture mapping: You can download the files to try them on a real CoCo or an emulator here: https://sites.google.com/site/rveilleux/coco3home/rems-coco-3-files 7 Quote Link to comment Share on other sites More sharing options...

Charlie_ Posted August 21, 2014 Share Posted August 21, 2014 https://www.youtube.com/watch?v=z6Mc_7GxvSw This is fantastic! I recorded this to tape and it loads up and plays great on my CoCo1. 1 Quote Link to comment Share on other sites More sharing options...
John_L Posted August 27, 2014 Share Posted August 27, 2014 It's interesting to note how modern games that entertain millions and earn as much, like flappy bird, angry birds, bejeweled, and candy crush can not only be faithfully recreated on a Color Computer 3, but done so without the 3 even breaking into a sweat.

jhd Posted August 28, 2015 Share Posted August 28, 2015 Wow, these are really impressive demos! While it is not new, does anybody remember the "original" Coco demo used in some Radio Shack stores ca. 1983? I only saw it a few times, around when I first bought my Coco, and all I remember was a scrolling Tandy/Radio Shack logo that changed size and colour as it went along. It was very impressive for the time. For whatever reason, I do not recall having seen it on any store demos in later years. Quote Link to comment Share on other sites More sharing options...

Nebulon Posted April 20, 2017 Share Posted April 20, 2017 He's not done yet, but... https://drive.google.com/file/d/0B1sgl615FlGnbG9GNjVncVhEZWc/view What machine is this running on? Quote Link to comment Share on other sites More sharing options...
JamesD Posted April 21, 2017 Author Share Posted April 21, 2017 (edited) What machine is this running on? That is a CoCo 2 with a 6309 CPU. A regular 6809 gets a slightly lower frame rate. There is a way he might get an even faster frame rate on the same machine with just a 6809, but it would require adding some RAM addressed in the ROM space and using the high speed mode. That would basically be a cart plugged into the expansion interface along with the SD interface. Someone gave me such a RAM board but I haven't tested it to see how much faster code would run yet. *edit* That would run pretty much the same on a CoCo 1 btw.

Nebulon Posted May 5, 2017 Share Posted May 5, 2017 Cool to hear those songs on the Color Computer again. Pretty sure I have some of those on disk somewhere. And for those who say the Tandy Color Computer can't play music and animate graphics at the same time... https://www.youtube.com/watch?v=azqvWgnAbnw 1 Quote Link to comment Share on other sites More sharing options...
