He's also done quite a few examples of converting SNES games to use the much faster SA-1 chip too, which runs at a very zippy 10.74 MHz:Īlso, just for record, if you compare what Vitor managed simply moving Gradius III to SA-1 (again, running at 10.74 MHz) vs what Aaendy managed with the much slower FastROM (at 3.58 MHz) and some properly optimized code, it shows you that it's mostly all about just doing things right more than anything else: It was never truly a SNES hardware problem, but really a publisher and even Nintendo problem (for even including it as an option in the first place).īy the way Vitor Vilela has also been doing some great work in this area of converting a bunch of SlowROM games to FastROM.
When, to get rid of most of the slowdown we see in all these SNES games, all they had to do was use the slightly more expensive FastROM cartridges and this all could have been avoided. It just shows you how many publishers shafted SNES owners time and time again by going with SlowROM over FastROM to pinch a few pennies. Because of this, it isn't unusual to find games that were originally written for FastRom banks and that were later converted down and shipped for slower chips. I have converted over 60 SNES games to fastrom! There is a running, up to date list that you can find right here! - kando🚀(#SMKDX) March 22, 2023Īs KandoWontu explains in a Reddit post on the subject, developers back in the day likely opted to ship with the slower mode enabled due to cost, as SlowRom chips were cheaper to manufacture. Quick reminder! (And for pinning purposes) KandoWontu is therefore patching the ROMs to take advantage of the faster mode and its 33.58% quicker processing times. SlowRom runs the CPU at 2.68 MHz, while FastRom runs it at 3.58 Mhz instead.
If you're wondering how these patches work, the Super Nintendo was basically created with two Rom modes in mind that took advantage of different CPU speeds. This means that you can now play a wide range of classic SNES games with faster loading times, less lag, and more responsive controls. KandoWontu, the talented hacker behind the Star Fox EX Exploration Showcase, has recently been releasing a bunch of new FastRom conversion patches for the Super Nintendo's library of games with the number now exceeding over 80 titles (thanks GBATemp!).
