8-bit acorn emulators • Re: B-Em Tape Overhaul v3 (SAVE support, autotests)

I'm open to suggestions about how to lay out these controls.

The tape inlay square is now clickable, so you can cycle through all the scans that are embedded in the UEF.

I'm unsure what the best size for tape inlay scans is. Chunk &7 implies use of an 8 bpp indexed or greyscale image. No compression is available, although the resulting UEF gets gzipped so it's probably something similar to PNG in the end. I think the sensible candidates for chunk &7 are either 128x128 (about 16K uncompressed added to the UEF file per scan) or 160x160 (about 25K uncompressed added to the UEF file per scan), although my PHP script uef_inlay.php can add scans at any size. The square here is 160x160.

There already exists a record indicator lamp next to the play indicator, but I need a record button also. Having to switch to record mode via the Tape menu is really irritating when one would expect a control for that to exist in the tape control window as well. Don't know where the button should go, what it should look like, or whether the record indicator should live inside it.

Don't know whether the 7 segment and other controls should have borders around them like the inlay scan does.

Then there are the indicator lamps up the right hand side. The labels for these are currently inlined into the source as 2-bit greyscale images (~250 bytes apiece embedded in the source) but I'm wondering whether 1-bit would work better with the fake 7 segment display and the other controls, which are drawn without any antialiasing. Also up for debate is whether having labels adjacent to lamps is a good idea, or if I should try to come up with little light-up icons instead without any text. Dunno.
