Re: tech demo

Go ahead and publish your BBCSDL conversion whenever you're ready. :) OK (listing below). Thanks, Richard. It runs well and looks nice on the 3 systems I ran it on (Windows, Linux Mint & Ubuntu, and a Raspberry Pi 4). Here's some shaky hand-held video of the program running under Raspbian Buster on...

So if you don't want me to publish a conversion that's fine, but I don't think it's reasonable to expect me not to do it for my own satisfaction.

David.

Re: BBC BASIC for SDL 2.0 version 1.08a released

I have run dlgdemo.bbc with BBCSDL versions 1.06a, 1.07a and 1.08a under Windows (SDLIDE). No problems at all with regards responsiveness with v1.06a (clicking a 'List box item' whether very short, short or long mouse button presses always results in the item being selected).
