vdub_bobby Posted July 29, 2005 Share Posted July 29, 2005 Like the title says. 900508[/snapback] Incidentally, if anyone missed it, I completely ripped off (with Alex' kind permission, of course) his watery effect for the Go Fish! title screen. Just thought I'd give credit, and thanks, where it is due. Quote Link to comment Share on other sites More sharing options...
attendo Posted July 31, 2005 Share Posted July 31, 2005 Pretty cool effect, taking the 2600 to the edge Quote Link to comment Share on other sites More sharing options...
Alex H Posted August 1, 2005 Author Share Posted August 1, 2005 Here's another little scroller demo. Binary only this time until I get it cleaned up. I wrote this on a PAL machine (PAL60) and haven't sorted out NTSC colours yet. The background should be red/blue but will be purple/green in NTSC. Runs ok in Z26 (press the "-" key to switch to PAL colours) but Stella chokes on this with my 3GHz machine! pscroll.zip Quote Link to comment Share on other sites More sharing options...

+stephena Posted August 1, 2005 Share Posted August 1, 2005 Runs ok in Z26 (press the "-" key to switch to PAL colours) but Stella chokes on this with my 3GHz machine! 902258[/snapback] With the current CVS version of Stella, it runs just as well (or poorly) in Linux as on z26. Both take up 100% CPU time. I'll test in Windows when I get a chance, and also in OpenGL mode in both. This type of game changes almost every pixel on the screen, so it's bound to be quite slow, as the whole screen is a dirty rectangle and must be updated. I'll research this to see if the emulation or screen updates are causing the slowdown (I have a feeling it's the latter). Also, the speed of the machine is not as important as the video subsystem (what type of video card, resolution, depth, etc). SDL for Windows is not as optimized as for Linux, so that should be taken into account as well. Quote Link to comment Share on other sites More sharing options...
belial Posted August 1, 2005 Share Posted August 1, 2005 On my old 500 linux machine both demos run normal with z26. No problems. And a big compliment, those scrolling demos are looking great. Im feeling a little bit "small" when i look at my own stuff and compare it to this. Quote Link to comment Share on other sites More sharing options...
harbaum Posted June 15, 2014 Share Posted June 15, 2014 Just tried wscroll on the a2601 FPGA core. The scroller is there, the music is there, but the reflections aren't ... odd ... Quote Link to comment Share on other sites More sharing options...
