Alienate demo don't work well

[mabrilG]

I try this demo in serveral configurations but allways crash after the clean screen effect, in original hardware work correctly. On the other hand, the sound with 'General Sound' configuration don't work.

Can download and try it here: http://www.pouet.net/prod.php?which=10531

Thanks for all the work done to make this perfect core.

Running the file linked at the top of that page: http://www.zxdemo.org/f/200308/alienate_tap.zip on zxsp, running on a MacBook, it crashes at the same place. Assuming you mean just before this time: https://youtu.be/Ee_mszc4kjA?t=47 ?

Yes, Mister core crashes in the same place, after the image change. Fail restarting the spectrum with a constant sound.

With a breakpoint at $0773, I can see it is trying to load "alien12" but none of the blocks in the .tap are "alien12". There is "alien0", "alien1" etc. through "alien5". After the wipe finishes at $07c5a, it pages in bank 6 at $c000, and jumps to $cd9d - but it's all zeros and it crashes. I tried the various options, Pentagon and Scorpion - plus the Gen Sound - but all try to load "alien12". [edit: correction; Gen Sound just hangs on a black screen, and alien12 is in the .tap - this was not the issue at all]

In original hardware, what configuration is known to work - and how was the .tap file played back?

The demo should work in USR0 mode, not by loading via the "Tape Loader" option in the main menu.

In original hardware I use setting: timings (Spectrum) and music (AY chip). The .tap file have been loaded with DivIDE and esxDOS.

Demo works fine. At least in latest release. 1) Set ULA-128 and Spectrum 128K/+2 in settings. 2) load the tap. 3) press F10 (same as USR0) 4) in menu of demo choose "Spectrum" mode.

Thanks to everyone! With F10 (USR 0) mode the demo work perfect.

I close the issue.
