tebe Posted February 7, 2010 Share Posted February 7, 2010 it works, but Altirra not show background "trash" Quote Link to comment Share on other sites More sharing options...
Rybags Posted February 8, 2010 Share Posted February 8, 2010 Lots of letter B looking things in a worm trail, in narrow screen mode. Background looks like it's just alternating between a couple of screens of random data. Quote Link to comment Share on other sites More sharing options...
Mclaneinc Posted February 8, 2010 Share Posted February 8, 2010 I just get the green B's and a black background? Quote Link to comment Share on other sites More sharing options...
Rybags Posted February 8, 2010 Share Posted February 8, 2010 (edited) VBXE on real hardware has random contents in it's RAM when the machine's powered up. Maybe it's worth implementing something like that in Altirra - might be helpful for programmers to remember to clear their workspace first.

phaeron Posted February 9, 2010 Share Posted February 9, 2010 Heh... yeah, I got burnt by this too. Here's a version of Altirra that fills memory with junk on cold reset: http://www.virtualdub.org/beta/Altirra-1.6-test3.zip http://www.virtualdub.org/beta/Altirra-1.6-test3-src.zip The pseudorandom fill seed is constant in this version; I couldn't decide whether a varying the seed was a good idea or not. On one hand, varying the seed would expose more problems where programs are relying on uninitialized memory. On the other hand, keeping the seed constant keeps the deterministic nature of the emulator's cold reset. Quote Link to comment Share on other sites More sharing options...
