I'm certain that it will work for Android emulators, since a friend of mine has played the beta on his Android phone. Check online for free emulators, I'm sure there are a few, but I can't remember the name of the one that my friend uses, sorry.
It's already available for GBA emulators, and it will be even after it gets done, because the file type won't change.
Make sure you check the rules, as your question has already been answered. (There is a rule about asking questions without searching to see if the question has been answered)
Instructions for how to download hacks (generalized):
- Check first post for download link
- Download patch file
- IF patch is in an archive, unzip it with 7zip (or WinRar)
- Use LunarIPS (or similar program) to patch the file to a Clean FireRed 1.0 Rom
- Rename the Rom to match the name of the hack (Optional, for organizational purposes)
- Launch the rom in an emulator of your choice. Enjoy!
NOTE: These instructions are generalized, meaning they are universal for Windows users (possibly Mac/Linux as well, I personally don't use either, so I can't say for sure) and should work with any hack.
NOTE2: Clean FireRed 1.0 must be obtained outside of PokeCommunity. Asking for Roms or links to Roms on the forum is against the rules. Just giving you a warning now so you don't break a rule without knowing it.
NOTE3: LunarIPS works with .ips patches. If the patch is in a different format, you will need a proper patch program to use it. I don't use other formats, so I don't know what the other programs are.
Hope this helps you! Also, please search the forum next time, as these instructions are all over the place xD
Have a good one!
