SF2000 Multicore Alpha 0.10

changes in 0.10:

There are now several choices of cores for some systems. It's up to you to pick the ones you want to use!

Recommended choices:

• Amstrad: amstradb (Caprice32)
• C64: c64 (Vice c64)
• GB/SGB: gbgb (Gearboy)
• GBC: gb (TGB Dual)
• GBA: gba (gpSP)
• Lynx: lnx (Handy)
• NES: nesq (QuickNES) for most games; nes (FCEUmm) for FDS games and the rest
• SNES: snes (Snes9x 2005) for most games; snes9x02 (Snes9x 2002) for certain slow games
  Note: the only stock emulator without a better multicore option is the Arcade section

We're considering these changes for a future release:

• remove amstrad (CrocoDS), built-in menu hangs when used for most things, Caprice32 seems fully functional alternative
• rename amstradb (Caprice32) to amstrad; if there's reason to keep CrocoDS, rename it to amstradb
• rename gbgb (Gearboy) to gb; make it main GB emulator; keep TGB Dual as gbc for Game Boy Color only
• remove gbav (VBA Next), it is slower than stock GBA emulator and gpSP core
• remove mgba (mGBA), it is slower than stock GBA emulator and gpSP core
• remove c64f and c64fc (Frodo and FrodoSC), they are slower than Vice x64 and Vice x64sc
• remove lnxb (Beetle Lynx), it is slower than Handy
• rename nesq (QuickNES) to nes; make it main NES emulator; keep FCEUmm as fds only for Nintendo FDS emulation
• remove nest (Nestopia), it is slower than stock NES emulator and the other NES cores

Updated Cores:

Amstrad

• added Caprice32; full speed and full featured
• fixed Caprice32; disk swapping (using m3u files: Y+R for next disk/tape; Y+L for previous disk/tape)
• fixed Caprice32; button mapping: Y+START brings up keyboard
• fixed Caprice32; increased brightness (opt file setting)

Arduboy

• fixed Arduous; timing is accurate, now has sound, still slow

Atari 5200

• fixed a5200; full speed and stable

Atari 7800

• fixed Prosystem; full speed and now with sound

Nintendo Game Boy Advance

• added VBA Next; slow and probably not needed?
• added mGBA; very slow, high compatibility, probably not needed?

Nintendo NES/Famicom

Internals (affecting all cores)

• kobil: FPS display (off by default; turn on by editing multicore.opt, or setting it in a core opt file)
• kobil: new opt behavior: multicore.opt is global settings file that applies to all cores
• kobil: new logging behavior: only log when a log file already exists (so delete the file to disable logging)

• osaka: fixed stereo->mono mixing, video code updates and fixes including new "stock" scaling mode
• ommokazza: fix ntsc overscan issue

  you run afterward will also have the fix applied. This must be done
  once each power on, as powering off resets it!

  (affects multiple cores, and maybe stock emulators too in some cases)
