Miyu and Fay in Star Fox (Super Nintendo) Romhack

Description

"What are you talking about? They were always there!"

Experience the original Star Fox, with Miyu and Fay from Star Fox 2 added to the team! All cutscenes have been edited to include them, including all-new dialogue courtesy of Joshua Schaeferhund!

This is "Phase 1" of the development of the upcoming major Star Fox hack, Star Fox CD. Consider it a preview of what is to come.

Patches are available for all revisions of Star Fox, with a choice between 21Mhz Super FX + fast multiply mode, or 10Mhz Super FX, depending on your preference.

1.4.2 - 5/12/2026

Added MSU-1 support from my Star Fox MSU-1 patch (as requested).

1.4.1 - 4/21/2026

Fixed hyperjump rumble not working on hardware with LRG prototype rumble pad
Fixed another potential bug in the teammate PATH scripts

1.4 - 4/19/2026

Added Miyu and Fay voice SFX - A huge optimization was found in the sound driver which freed enough space to add these!
Fixed centering of names on score screen
Score screen meter widths fixed
Fixed shield meter color not changing with shield power up
Small rumble system optimization

1.3.2 hotfix - 7/19/2025 - Fixed extreme instability on Kando's SNES

1.3.1 hotfix - Fixed rumble bug where if you pressed start at just the right time in the intro, the Attack Carrier's rumble sequence will continue instead of being stopped

VERSION 1.3 UPDATE - July 18, 2025

Added the rumble support from Star Fox Shindou Edition (as requested). Tested and working on hardware. See the Shindou Edition page for usage instructions and credits.
Fixed a couple more potential bugs in the teammate PATH scripts
The RNG system has been updated to match that of Star Fox CD, in an attempt to address the issues with random teammate selections for chases/dialogue brought up by Wolfric. Every boot will have a different seed now, so every random teammate chase/dialogue will be different on every playthrough.

Such an amazing romhack super close to perfection

I've played through two different routes so far. Only issue I can bring up is: Fay takes over all the mid-mission Slippy dialogue. She's the one that has needed rescue most of the times, followed by Falco and then Miyu.

I think Slippy should be right behind Fay in needing to be rescued, because right now he's been left with no dialogue aside from opening and ending stage dialogues.

With that said, this has become the default way for me to play this game. Here's hoping the two girls can be added to Star Fox 64 in the future....

Edit: The hacker revised the hack and the dialogues seem to shift character priority better now! Can't rate this hack any lower than 5 ⭐s now

Now not to ask too much, this hack is already super fun to replay the game a bit differently with new pilots to spice up dialogue, but any chance of the 64 HUD making over to it? It reaaaally helped with precision shots XP

HI, very cool mod, I really liked it! I'm very interested in this Star Fox CD that you're planning. Small problem I noticed: Whatever I tried, the Rumble feature did not work on ares v147. I tried with Xbox One and 8bitdo SN30 pro. But it worked perfectly with Mesen! It's such a great feature! Also, would it be possible to have the option for the crosshair in third person? Shoutout to Video Game Esoterica on youtube for making me awwre of this romhack! Thank you very much for making this!
