“The Star Fox Team is back! But this time, their mission is to fight for their very existence!

The Mario Bros. have decided that the Star Fox franchise no longer has a place within the grand Nintendo universe, and has set out to destroy the Lylat System forever, with the help of characters from more successful Nintendo IPs! They have also posed as Andross in order to hire the infamous Star Wolf team, a rival band of mercenaries led by Wolf O’Donnell, to distract Star Fox while they pull off their plans! Can Fox and his team put aside their former friendship with the Nintendo All-Stars to save both the Lylat System and everything associated with their franchise?”

Experience the amazing power of the Super NES and the SuperFX chip and take full control of Star Fox!

Thank you for answering my questions in the doom-snes-modding subsection of your Discord!

This is from https://romhackplaza.org/romhacks/super-mario-kart-rumble-version-snes/ and answers my SNES Rumble Controller question: = = = = = = Notes: Do NOT plug more than one SNES Rumble Controller into any Super NES. Do not use SNES Rumble Controllers alongside or attached to a multi-tap. The emulator Mesen will only rumble certain controllers plugged into the host system. The author of this ROM hack used a Dual-Sense rumble controller with Mesen 2.1.1 on GNU Linux to test rumble functionality. Do NOT redistribute, sell, trade, or exchange pre-patched ROMs through any means for cash, crypto, or other assets. PIRACY IS A CRIME. = = = = = = Then last week, I had a refund through Limited Run Games on 3 of the 5 controllers. I said that I could use 2 in case one of them breaks. I still want to play Star Fox Ex from Ebay. However, would somebody please answer my questions above about which SNES clone systems I'm supposed to use according to pages 7 and 9 of the Star Fox Ex manual?

Briefly watch this Madlittlepixel video so that we are on the same page with the information that I have: zXjcwN_SrtU On August 8, I bought SNES Doom with 5 Rumble controllers from Limited Run Games. The 5 controllers are because I want to eventually buy a SNES Multitap (A connector for controllers 2 through 5) & the Star Fox EX cartridge from Ebay. You posted the Star Fox EX v1.11.02b.7z PDF manual. It's up to 5 players. On page 7 of the PDF, it says: “WARNING: It is strongly discouraged to use Multitap on a real Super NES, as it may result in damage to your sonsole and its power supply.” Then which SNES clone console should I use? I have a SNES, but not a Retron, and not a Super Analogue NT. Would I be able to play the Star Fox Ex cartridge with 5 Rumble Controllers without a problem? On page 9 of the PDF manual, it says: “Does not work on Super NES hardware or …” That was discouraging. In the meantime, I will be looking for information on other SNES web pages for an answer.

Hi friend, first of all congratulations on your work. This latest version 1.11.02a, on my SD2SNES, starts the opening and then cuts to a screen saying report a bug. I played the version 1.02 normally.

Cheers! I'm new to Star Fox so I'm trying to play the original game through your hack before going to the new stuff but it keeps crashing on the Space Armada stage, the third one in the original route, my emulator is Snes9x 1.62.3 and SuperFX Clock Speed is 400% and CPU Overclock is at Max. Is it a problem on my end?
