Hi,

The readme indicates a bit that i386 emulation is also possible with blink, if that's correct my questions are:

does the x86_64 "limitation" only apply to the loader?
is i386 emulation on par with x86_64 emulation?

The Blink codebase supports the i386 ISA, but Blink doesn't implement the Linux i386 int $0x80 system call abi for example. Since there's no system call interface in Blink for i386, the blink/loader.c code will reject an i386 ELF binary if you try to run one. Where you can currently use i386 code would be if you used blinkenlights -r foo.bin to load a real mode program from BIOS, and then the program put itself in protected mode. In that case Blink would be doing i386.

Nice! The emulator part is what I need. I'll give it a try and report back
