Hack description
Updates: -Fixed screen flashing after boss defeated
-Fixed 60FPS mode (wasn't doing animations/color cycles at 60fps)
-Added: 2 more fun tests
-Renamed: SF60FPS Variant 2 to SF20FPS 60FPS Elements
Hello!
This is a set of patches to unlock 30 and 60FPS mode for Starfox!
1) How is this achieved?
2) How to run it?
3) Can to see the FPS

1) How is this achieved?
The game has 3 IRQ routines to complete the game cycle of strats (movement/attack/health/etc routines), drawing the screen etc. It does this in 3 game cycles, which limits the game to 20FPS at max.
What has been done is the IRQ routines have been programmed to run right after each other without waiting a game cycle, from irq 2-3 for 30fps mode and from irq 1-2-3 for 60fps mode.
Additionally, every frame will also be drawing as well as doing the strats. What has been done is the strats will only process every 2/3 frames for 30/60fps while still drawing it every frame. This slows the game back down to its ORIGINAL pace.
Also attached is a FULL SPEED patch that does not slow the game down to its original pace (just for fun).
2) How to run it?
The game does NOT run on console. It requires most importantly a CPU overclock. The patch requires USA 1.2 UNHEADERED rom.
SNES9X - CPU OVERCLOCK under HACKS set to MAX
BSNES - CPU OVERCLOCK set to 126% CPU speed (a .BML file is also supplied, put in the same folder as the rom with the same name for BSNES)
MESEN - Set to "Wait 60 scanlines AFTER NMI"
Retroarch SNES9X - CPU OVERCLOCK may be called "REDUCE SLOWDOWN" under HACKS
For the best experience, visit our discord for a custom SNES9X build with faster cpu overclocking ;)
3) How to see the FPS
Just press A+B on the title screen to enable the on-screen FPS display.
4) DISCLAIMER
The FPS may fluctuate, especially in 60FPS mode. This is simply due to emulation restrictions. 30FPS mode provides the most solid experience. 60FPS can almost be achieved solidly using a custom SNES9X build that is provided on our discord.
This hack simply unlocks the game's artificial limitations.
