If you like the program, please donate a few dollars, this will help me to continue to work on emulation projects.
For getting started, here are some notes on emulation/debugging controls, BIOS files, and ROM-Image formats for NSS and SFC-Box cartridges.

Versions

complete release notes for all versions

Features

The program is 100% assembler code. Accuracy should be quite high (if not: bug are reports welcome).
Controllers: 1-2 Joypads, Multitap, Mouse, Lightguns (via mouse), NTT Data Pad, X-Band Keyboard, Twin Tap's, Barcode Battler, Pachinko Dial, Exertainment Bike
Coprocessors: SA-1, GSU, DSP, ST010/11, CX4, OBC1, S-DD1, SPC7110, S-RTC, RTC-4513, SFC-Box, NSS arcade cabinet
Add-ons: Satellaview, Turbofile (TFII and STF)
Debugger: Assembler, Disassembler, Xboo-Upload Function (for testing code on real SNES).
Requirements: Win95 and up, around 8MB RAM, around 200MHz (tested)
(on 1GHz computers, most games can run 5-10 times faster as on real hardware).

Known Problems

Interlace Mode (vertical hires) isn't yet supported (used only by 3 games or so)
Offset-Per-Tile Mode isn't yet supported (used by Starfox... and probably by some further games...?)
GUIs of Copiers and Cheat Devices should be working (but without actually emulating FDDs or Patches)
ST018 isn't yet supported

Sample Code

Magic Floor - a small search game (includes sample source code for A22i-assembler and Xboo-Upload)

Test Programs
Below are some test programs for confirming some still unknown details of the NSS and SFC-Box hardware. If you do own one of that consoles (and an EPROM burner): would be great if you could send screenshots (photos) of the test results! Usage: Burn the binary to EPROM, remove the original BIOS from mainboard, and replace it by the test program.
