Lotus 1-2-3 v4.0 for DOS hangs on splash screen, but this happens with all models and CPUs in PCEM, I tried a copy of the same virtual hard disk in Virtualbox and there runs OK...

Yeah the CPU emulation is far from perfect. There's also another issue that affects all emulated CPU's from 808x to 386, and that's the prefetch not working right, which causes, on 808x (probably also other CPU's but 8088mph is not really designed for those anyway), 8088mph's credits to hang (they work on real hardware and DOSBox), and on all the affected CPU's, SnatchIt to hang (works on real hardware and PCE). I reported the issue to SarahWalker last year, but so far it still hasn't been fixed.

I don't remember you reporting that. Link to the thread?

- SarahWalker: I reported it to you on IRC last year and you said you'd look into it. But if needed, I'll create a thread too.

I'm amazed you actually expect me to remember things mentioned briefly on IRC a year ago.

You're right. :p Well I just opened a bug report thread about that. I should have done that back then already.
