The DSP-1 is the most varied and widely used of the Super NES DSPs, in more than 15 separate games. It is used as a math coprocessor in games such as Super Mario Kart and Pilotwings that require more advanced Mode 7 scaling and rotation.
17 Φεβ 2024 · The SA-1 coprocessor, or Super Accelerator 1, is a somewhat fascinating chip in that it has quite a lot of hardware that almost no games ever used. Its primary attraction is an additional 65816 CPU clocked at 3x the speed of the SNES CPU, and most of the SA-1 games only used it for that.
6 Αυγ 2018 · I've been compiling a list of every SNES homebrew & hacked ROM that utilizes the SA-1 chip. This includes hacks, translations, demos, tools, etc. Please let me know if anything is missing, or if there are new versions of any ROMs in the list: http://krikzz.com/forum/index.php?topic=8051.msg62079.
The SA-1 chip, which stands for "Super Acceleration 1", is a supplementary 65C816 processor (the same processor the SNES uses), with an increased clock speed of 10.74 MHz.
The SA-1 is a coprocessor capable of running at four times the base speed of the SNES main CPU when access does not conflict with that of SNES CPU, DMA or HDMA processing.
Request. checking google, i can only find that 34 games used it, super mario rpg included, but nowhere can i find the other 33 games.
