Emulation note

A note on emulation

Flash cartridges like the FXPak Pro run native code on real hardware, but they are not full emulators. The Super Nintendo relied on a number of special enhancement chips embedded inside certain game cartridges, and not every one of these can be reproduced from an SD card.

Enhancement chips

Some of the most famous SNES games shipped with extra silicon to expand the console's abilities. The Super FX chip powered 3D style graphics, the SA-1 accelerated processing, and the DSP and Cx4 chips handled math heavy tasks. Reproducing these in real time is demanding. Super FX SA-1

What this means in practice

  • Standard games without special chips run perfectly from a flashcart.
  • Some enhancement chips are emulated on the cartridge using an onboard programmable component, with varying completeness.
  • A handful of titles may run with minor glitches or not at all, depending on firmware support.

Check compatibility lists

Before assuming a chip heavy game will work, consult the flashcart's compatibility notes and keep firmware up to date. Support improves over time as the community refines the cartridge's onboard emulation cores.

For the vast majority of the library, a flashcart delivers an authentic experience. The handful of exceptions are well documented, so you can plan around them or fall back to original cartridges for those specific titles.
