Problem with Atari 8 bit demos #30

Open lencio opened 1 year ago

lencio commented 1 year ago

I tried to run this two demos on Atari 800 core, but not works. Alley Dogs stop in minute 6 (320k compy) (https://www.youtube.com/watch?v=gTHxkxdoRgU) Rewind demo simply not work. (1MB required) (https://www.youtube.com/watch?v=3s2vqN1jWgU) Any ideas? I try all configurations, and combinations.

Link for demo's download: https://demozoo.org/platforms/16/

Thanks!

I will not open another issue for this, as this is probably related. Today I noticed that the Joyride demo has a problem loading (it boots and the first part loads OK, but later parts, or the complete disk 2 do not load with animated+sound loading screen, the "crash" is witnessed by a pink/purple background and freeze upon any key press). Now, I know from real hardware this demo is very sensitive to all kinds of SIO mods (it won't load from a PBI device, or with HSIO patch) and it relies on serial interrupts, so I replaced the "shipped" HSIO patched OS rom with a stock one from my XE in the hope that was it. But it is not, Joyride still does not load.

(Note: even though problematic, the emulators have no problems with it, nor stock hardware with modern SIO devices like SIO2PC or SDrive-MAX, provided HSIO is not there).

Steps to reproduce: boot the second disk of Joyride, the Joyride banner will appear in green, the background turns pink, the music plays, upon any key press the sound freezes. Link to Joyride download: http://www.atarimania.com/demo-atari-400-800-xl-xe-joyride_s11309.html
