(Including popular stuff like Yohsi Island, Mario Kart, etc.) that used the SNES as a glorified gamepad-prober + framebuffer and relied on extra chip to do the game. Probably half of the SNES games you played weren't *actually* *SNES* games, but SA-1 games, Super FX games, etc. 10 is closer to the number of *different types of chips* available for SNES carts, with many dozens of carts using one of these. Huh, you're seriously underestimating how much widespread enhancement chips were on the SNES. Some SNES carts (10 in total, from what I found) had a processor chip (the SA-1, among others) that allowed for game quality beyond what the console itself could produce. But we shouldn't underestimate the human capabilities." Vilela notes that the lack of slowdown "makes it incredibly super difficult" and even suggests that "some arcade segments of the game do not look RTA (real-time action) viable with SA-1.
GRADIUS III ROM PATCH
As if that wasn't enough, the patch even slashes the game's loading times, cutting a full 3.25 seconds from the notably slow startup animation. That's even true in the game's notorious, bubble-filled Stage 2, which is transformed from a jittery slide show to an amazing showcase of the SNES' enhanced power. It also keeps its silky smooth frame rate no matter how many detailed, screen-filling sprites clutter the scene. The result, as is apparent in the comparison videos embedded here, is a version of Gradius III that Vilela says runs two to three times faster than the original. Besides sporting a faster clock speed than the standard SNES CPU (up to 10.74 Mhz versus 3.58 Mhz for the CPU), SA-1 also opens up faster mathematical functions, improved graphics manipulation, and parallel processing capabilities for SNES programmers. "In action, though, any scene with more than a handful of enemies would slow to a nearly unplayable crawl on the underpowered SNES hardware." From the report: The key to Vilela's efforts is the SA-1 chip, an enhancement co-processor that was found in some late-era SNES cartridges like Super Mario RPG and Kirby Super Star. "In magazine screenshots, the game's huge, colorful sprites were a sight to behold, comparable to the 1989 arcade original," writes Orland.
Ars Technica's Kyle Orland reports that Brazilian ROM hacker Vitor Vilela has released a ROM patch for the hit arcade game Gradius III, creating a new, slowdown-free version of the game for play on SNES emulators and standard hardware.
