On windows noticed that PICO-8 generates corrupted newlines from your template:
"\r\r\n" ( 0D 0D 0A ) instead of "\r\n" ( 0D 0A )

This appears to not affect browsers much but it sure affects text editors like Notepad++, plus it makes the HTML pointlessly bigger :p

A solution is to convert your template to unix newlines format ( 0D 0A -> 0A ) to get around the PICO-8 bug... besides that's the proper format you should use anyway. ;)

Windows systems really need to stop doing the \r entirely.

Just, stop.

There's no need to emulate a physical printer.

yeah it seems pico-8 unconditionally adds CRs on windows...

Nice theplate!
It's fixing the bug with the stat(4) function on browser?

@MrBigaston: I don't think so, since I wasn't aware of that issue. I see it's about getting the clipboard content but I couldn't find more info... maybe it isn't implemented yet?
