Hi,
Some BIOS, [Shift] and [Ctrl] cannot work.

https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/425979

Suggest

• Use ↑ to jump
• Use ↓ to crouch
  Or
• Use w to jump
• Use s to crouch

Thank you for raising this issue.

I used the modifier keys because this solution took less space, but after some of the last refactors there are some bytes left, so I think this might be doable.

Would you want to work on this?

What I use is EFI grub 2.06.
https://github.com/M-L-P/grub2-brunch/releases/tag/0.0.6

menuentry "DinoChrome" {
  linux memdisk raw
  initrd dino.img
}

It can run on CSM mode, but [shift] and [ctrl] cannot work on my old PC with CPU Intel Core 1 Gen.

What I am thinking is whether there is a way to make dino work on only UEFI.

Maybe yes if someone would have adapted it from dino.img to dino.efi.

Above it, at least I would like dino.img can jump and crouch on my old PC
