Super R-Type SA-1
Vitor Vilela's SA-1 Root patch moves Super R-Type onto the SA-1 coprocessor, wiping out the game's infamous slowdown and cutting its loading times.
What it does
Super R-Type is remembered as much for its slowdown as for its tough stages. This patch is part of Vitor Vilela's SA-1 Root series, which reworks SNES games to run on the SA-1 enhancement chip, a much faster processor that was used in some later cartridges. With the game's code running on it, the slowdown disappears and the pauses between scenes become much shorter, while the stages, enemies and difficulty stay as Irem made them.
Version 1.3 builds the patch from a single source for the American, European and Japanese releases, with a separate patch for each. The work was made possible by trace logs supplied by Erivando_BR, and kccheng helped with testing.
Playing it
Apply the patch for your region to your own copy of the game, following the instructions in the creator's repository. It runs on emulators such as Snes9x and bsnes and on real hardware with an SA-1 compatible flash cart.
