Nintendo - SNES / Famicom (Snes9x 2010)¶

Background¶

Port of Snes9x 1.52+ to Libretro (previously called SNES9x Next). Rewritten in C and several optimizations and speedhacks.

Provides more favorable performance thresholds at the cost of accuracy. DO NOT use this core unless you have underpowered hardware and the mainline Snes9x core and the bsnes/higan/bsnes-mercury cores aren't fast enough

This core is part of a group of Snes9x cores that are snapshots from the year their code is based on. (Snes9x 2002, Snes9x 2005, Snes9x 2005 Plus, Snes9x 2010)

Core options¶

Settings with (Restart) means that core has to be closed for the new setting to be applied on next launch.

SuperFX Overclock [snes9x_next_overclock] (Disabled(10MHz)|40MHz|60MHz|80MHz|100MHz|Underclock(5MHz)|Underclock(8MHz))

Overclock or underclock the SuperFX chip. 10Mhz is stock clockspeed.
Reduce Slowdown (Hack, Unsafe) [snes9x_next_overclock_cycles] (disabled|compatible|max)

Many games for the SNES suffered from slowdown due to the weak main CPU. This option helps allievate that at the cost of possible bugs.

Example video here

compatible: Reduce slowdown but keep as much game compatibility as much as possible.

max: Reduce slowdown as much as possible but will break more games.
Reduce Flickering (Hack, Unsafe) [snes9x_next_reduce_sprite_flicker] (disabled|enabled)

Raises sprite limit to reduce flickering in games.
