Do you have a compiler for .uf2?

[Mr-Amnat]

Please help share .uf2 pi pico vga.
I can't compile it.
Thank you.

[markadev]

Yes! You can download the compiled .uf2 files from: https://github.com/markadev/AppleII-VGA/releases

Just choose the one for your Apple II model (II+ or IIe)

Do you happen to have builds for apple II europlus? I am trying to get it running and I tried both iie and iiplus files, yet all I can see are the inverted @ signs and a blinking cursor in four lines (cycling through the four cursor positions when I advance on the lines on the composite connected monitor)

[jakubpolomsky]

Oh nevermind... I realized I was using the 74LS instead of LV... now everything works perfectly fine

[markadev]

Cool, glad to hear you got it working!

Hi, I have the same problem (inverted @ only, and after some hours I see flickering some LowRes artifacts). I have LVC buffers installed, though, could the be fake ones? I ordered them from china...

Hey there. It's always possible they could be fake but you can also double-check the 3.3v supply on the ICs and if you have a scope then you can check pin 31 on the Pico to see that the Apple 1MHz bus clock signal is making it through.
