This updates usb2snes to the sd2snes 1.8.0 firmware.

  • msu and dsp chips have been added back into the base fpga file.
  • The save state patch has been updated to work with the new fpga_base.bit file. Older versions will no longer work. The save state patch is provided as-is and will not be updated or supported.
  • The additional fpga functions (required by the save state patch) are not supported by gsu, sa1, or other special chips.

It needs to be applied on top of a working 1.8.0 or 1.8.0+sa1 base. Check that System Information in the menu says 1.8.0-usb-v8.

This updates reduces the amount of slowdown j-league sees when many players are on the screen. It also changes snes/sa1 interfaces which may improve stability on certain consoles.

This update fixes the reset bug and changes the way the snes can access the sa1 chip. The reset bug has a random chance of happening when using the console reset button. The snes accesses to the sa1 chip had some corner case bugs and low performance - this change may potentially fix random crashes and slightly improve performance. This part of the sa1 is very sensitive to timing and the change may introduce new bugs. Revert to an older version if this one doesn't work for you.

This update enables some limited use of in-game hooks for reset via controller buttons. It also fixes a reset problem when loading a new fpga file (e.g. sa1) that would result in a black screen. Only sa1 games will have this fix. Partial binary coded decimal support has been added to fix a scoring bug in the smrpg beetle game.

This update targets problems in certain Marvelous romhacks, golf games, and Pachi-Slot Monogatari. It may fix crashes or performance issues in other games but that is not confirmed.
