SNES Star Fox now runs at a silky 60 fps thanks to a new hack

A demo of the hacked, 60 fps version star Fox Released this week (though the demo doesn’t get over 30 fps, as noted in the bottom-left corner).

If You Were a Nintendo Kid in the ’90s, You Were Probably Blown Up by How star Fox And Its SuperFX Chip Can render full 3D worlds on 1993-era SNES hardware. If you go back to playing the game today, though, you’ll probably be disappointed by the game’s choppy frame rate, which stops at a maximum of 20 fps.

The result is an extremely seamless experience that probably comes as close to matching the rose-colored memories you had in the early ’90s star Fox than ever in the original game.

design problem

try to accelerate star Fox Nothing new in the hacking and emulation communities. players over the years Overclocked SuperFX Chips either run emulator at high speed To try to increase the frame rate of the game.

The SuperFX chip is one of several cartridge coprocessors that an SNES emulator has to handle correctly.

But when these methods make star Fox Run faster (and smoothly), they speed up the game’s internal logic to the same extent. That means enemy ships and your Arwing fly much faster than Nintendo intended, an effect that throws the game’s excellent music out of sync with the auto-scrolling action on-screen. Triple the game speed to get the 60 fps experience makes it playable fast by all accounts.

The design and limitations of the original SuperFX chip make this a difficult problem to solve. in this kind of game star FoxSuperFX Chip Can take two full frame cycles To transfer its 3D images to the system’s video RAM (which despite using only 75 percent of the available screen real estate). Add in the calculation time for game logic, enemy movement, and more, and the game displays a new frame at just one-third of the SNES’s standard 60 fps rate.

“SuperFX games are a special case,” to emulator author (aka Bayu) Told Ars in 2019 Discussing an overclocking-focused update for them bsnes accuracy-focused emulator, “Since they don’t run at 60 fps due to the demands of the software that rasterizes the entire screen on the SNES, the game logic is designed around the frame rate. So even if you increase the speed star FoxThe game engine will seem to be running much faster now.”

slow your roll

To address this issue, Kondo’s hack reprograms the first game to run three frames’ worth of instructions (as measured in) IRQ routine) in place of one frame cycle (or two game cycles for 30 fps mode). But to keep gameplay from getting too fast, Kondo programmed his version to simply recalculate the game logic (or “strats”) every third frame (or every other frame for 30 fps mode). “This slows the game back to its original speed,” writes Kondo.

Unfortunately, Kondo noted that this hacked version of the game Still need help from overclocked SNES CPU and therefore, Won’t work on stock SNES hardware, Even in an emulator configured to run in overclocked mode, Kondo have warned that, in 60 fps mode, “the fps becomes very variable between 30-60 fps when there are some objects on the screen (60 fps playback also seems to have some problems with the speed of the music).

Limits aside, it’s too good to live again star FoxAction-packed gameplay without the nausea-inducing frame rates inherent in early ’90s 3D graphics (or the nausea-inducing game speed of previous frame rate hacks). we’ll play it together this weekend Our recession-free, enhanced copy of the SA-1 step 3 In trying to re-live the best version of our childhood.
