Excellent work!

I'm developing/playing around with an adventure game using ULAPlus and Nirvana+.

Very nice emulator - clean GUI - timing of ULA excellent for Nirvana+ (so probably excellent) in both 48k and 128kb mode - not all emulators manage that!

ULAPlus color palette working well - except for one thing: The borders - seems I get the normal ZX standard palette borders - when I look at other emulators and the ULAPlus spec I think this is wrong/a bug - they are limited to first CLUT of ULAPlus palette but should be taken from that not the "standard palette" colors.

This small tap file opened in Spectrusty (web assembly version) shows the correct border but shows pure "standard Spectrum green" in Spectron:

ghibli-v2-plus.tap.zip

Load it in Spectrusty for a comparison:

I you have the time to look at it - it would be great.

However: Excellent emulator, very slick work!

Hi Thomas,

I am glad you like my Spectron emulator.

And thanks for reporting an issue with ULA+ emulation. You are absolutely right about this incorrect border behaviour. And it should be fixed now, in the main branch and also I published new release in case you are using binaries. If you find any issues, just let me know.

Many thanks! Confirmed, latest OSX-arm binaries - correct ULAPlus border color!
