Will you need Homebrew to download it?
[OLD] SmileBOY - Game Boy emulator for SmileBASIC
Nope, but it will make things easier.
You can with the Fieldrunners exploit. Requires another hacked system and system transfer to get the title over with a hacked save, but DSiware hax has access to the parts of the NAND that you change to downgrade with a hardmod, so downgrading with it is definitely possible.Field Runners exploit is better anyway and allows downgrading.you cant downgrade 11.0.0-33 without hardmodding
What if you made it into a JIT (Just in Time) Compiler instead of an emulator. It would help with the framerates, I would think.
