Gradius III has been patched to use the SA-1 enhancment chip. This fixes the frequent slow downs on the original release. See https://github.com/VitorVilela7/SA1-Roo ... radius-III .
Konami would later release a version of Parodius on the SNES using the SA-1 to avoid the slowdowns that the original Gradius III had.
It's kinda interesting because the SNES had so many enhancement chips to choose from to make up from its limitations.
