Note: This version has some changes to the Megadrive driver. The driver is now based on the MESS software list.

 

The game shortnames are prepended by md_ to differentiate them from the arcade games where conflicts occur. FB Alpha will look for your roms in the normal zip names, you do not need to create a new copy of the games and prepend md_. It is advisable to have the Megadrive roms in the seventh or eighth rom paths to avoid conflicts with arcade games. Support files will need to retain the md_ in order to avoid conflicts, however.

 

All Megadrive games are now enabled (except for Virtua Racing because the SVP isn't emulated), most should work, however, some may not.

 

- Megadrive Changes

-- Updated Megadrive driver based on MESS 0.143u7 software list [barry]

-- Made the seventh rom path special like the eighth one so that Megadrive roms can be stored in one of the last two paths and still allow supplementary FB Alpha roms to be in a seperate path [barry]

-- Made the short name in the game selection dialog slightly longer to accomodate the Megadrive short names [barry]

-- Increased the maximum number for sek handlers to 10 [barry]

-- Added better SRAM support and support for custom mappers as per MESS

-- Removed menu option for making a datfile with both arcade games and Megadrive games, the two would conflict, and arcade and Megadrive dats need to be handled seperately [barry]

-- Updated the dat file creation module to remove the md_ from the Megadrive shortnames [barry]

- Added clone of Aquajack to the Taito-Z driver [barry]

- Added clone of Vigilante to the Vigilante driver [barry]

- Fixed music tempo and continuity in Item M90 and M92 drivers [iq_132]

- Added option to the YM2413 to decrease volume and used it to correct sound in the Mitchell driver [barry]

- Fixed the gun inputs in Zombie Raid [barry]

- Fixed the support file path creation for the IPS folders on app init [barry]

- Fixed immediate update of Apply Patches checkbox in game selection dialog when applying IPS Patches [barry]

- Added ability to search the drivers short name as well as the description in the Game Selection dialog [barry]

- Made the Game Selection dialog search interactive and removed the Search button [barry]

- Made the Game Selection dialog choose the current loaded game if a game is currently loaded [barry]

bsnes v083 released

 

This release adds preliminary Nintendo / Famicom emulation. It's only a week or two old, so a lot of work still needs to be done before it can compete with the most popular NES emulators.

 

It's important to clarify: bsnes is primarily an SNES emulator. That will always be its forte and my core focus. I have added Game Boy support previously for Super Game Boy emulation, and I've added NES support mostly for something fun to work on to break up the monotony of working on one system for seven years now. Obviously, I'd like the emulation to be accurate and highly compatible, but I simply cannot afford to invest the same amount of time and money into any other systems.

 

Still, either way the NES and GB emulation serve as fun side-diversions, and allow for a unified emulator interface with all of bsnes' unique features applied to all systems. My personal favorite feature is mightymo's extended built-in cheat code database that now also includes NES and Game Boy codes. And it even works in Super Game Boy mode now, too!

 

I'm also not worried about speed at all: so long as NES/GB are faster than SNES/compatibility, it's fine by me. Note that due to the NES audio running at 1.78MHz, and Game Boy audio at 4MHz stereo, a more sophisticated audio resampler was needed: Ryphecha (Mednafen author) has graciously written a first-rate resampler: it is a band-limited Kaiser-windowed polyphase sinc resampler. It is combined with two highpass filters to remove DC bias. The filter itself is SSE optimized, but even still, approximately 50% of CPU usage for NES/GB emulation goes to the audio filtering alone. However, you now have the best sound possible for NES and Game Boy emulation as a result.

 

The GUI has also been heavily re-structured to accommodate multiple emulators from the same interface. As such, it's quite likely a few bugs are still lurking here and there. Please report them and I'll iron them out for the next release.

- lots of other changes
