  on asm version, but now...
o FIXED: Flashing screen on Captain Commando.
o FIXED: Super Street Fighter 2 won't respond to joy-pad controls.
o FIXED: Final Fantasy V - text windows are partially hidden - background

o FIXED: ffmq might require MVN/MVP to always use a 16-bit accumulator.
o FIXED: Battle Toads crashes after player selection.
o Mode 5 graphics on snestest.smc Controller Test are corrupt - offset per
  tile not implemented. NO - H-512 mode not implemented!
o FIXED: snestest.smc locked up on Electronics test - IRQ never cleared.
o FIXED: Formation Soccer is doing DMA from a bad area of RAM to V-RAM -
  needed SPC700 emulation.
o FIXED: Pacman crashes and problems with sprites on title screen - v-ram
  reading problem.
o FIXED: New FF5 graphics problems on title screen.
o FIXED: MS-DOS machine with single joystick doesn't work.
o FIXED: Seiken 3 locks up - first in a IRQ loop (its never cleared) then waiting
  for sound CPU.
o FIXED: Metriod 3 has a corrupted screen and locks up.
o FIXED: Mechawarrior 3050 has major problems - corrupt screen, extreamly slow frame
  time, etc., etc. - needs SetByte and GetByte CPU push code. - So does
  Weapon Lord!
o FIXED: **Weapon Lord uses PCALL and TCALL in SPC-700 code **
o FIXED: Another World is transfering a lot of data using DAM to VRAM and $2180.
o FIXED: Soulblazer has minor h-dma glitches on vertical background scrolling.
o FIXED: Secret of the Stars no go - Sound cpu wait problem.

o FIXED: Memory map problem with Donald Duck (corrupt ROM image).
o FIXED: Comsmo Puzzle and Yuu Yuu all show "V-RAM increment" type

o FIXED: ILLUSION has horrible sound... (sample decode routine had a bug).
o FIXED: Find out why graphics are all squashed up on sensi soccer/ bman with old

o FIXED: aleste.smc has sprite display problems on title screen on tile-based redraw
  code.
o INFO: DKC3 crashes itself if V-RAM isn't filled with zeros!
o FIXED:Tazmania has stopped working - missing IRQ. Adding a field to
  Settings moved a variable being used in asm code.
o FIXED: Castleviana 5 and Sparkster use DMA address decrement to update sprites.
o FIXED: X-Men has some sprite glitches - but only on tile based redraw code -
  it blanks the screen early and then DMAs new spite tile data before the
  usual end of frame.
o FIXED: Super Punchout shows corrupt knockout timer when H-DMA is enabled.
  (was triggering H-DMA during a frame) - only trigger H-DMA during v-blank or
  h-blank, otherwise write to register is ignored.
o SOUND: Clayfighter, Tazmania, Madden 94-97, NHL 96-97, and WeaponLord
  all spool sound samples into APU RAM using H-DMA!
o FIXED: ASM version bug: SOUND: Super Punchout has lots of sound repeat problems.

o FIXED: Weapon Lord hangs on player selection screen (waiting for SPC700?).
o FIXED: Killer Instinct shows BG3 on title screen when it shouldn't.
o FIXED: Blank screen on Rock 'n' Roll Racing - DMA problem.
o FIXED: SFC Bastard has offset problems on Mode 7 graphics on title screen.
o FIXED: SOUND: SFC Bastard (bastardy.smc) locks with sound enabled.
o FIXED: GANBARE GOEMON 2 (sf16232a.078) requires SavedOAMAddr to be set in
  OAMAddr after end of frame (at max v_counter?).
o FIXED: SuperOffroad: The Baj has screen flash/timing problems during game - 
  skipping IRQs ? - It was reseting the H-IRQ position so another IRQ would
  occur on the scanline it was already on.
o FIXED: R-TYPE 3 has missing scrolling "space" background during game.
  (location $54 contains $10, needs to contain $11) - not a bug, when run on a
  real SNES the background is missing as well.
o FIXED: Toy Story plays sample that walks off end of memory - was causing 
  emulator crashes.
o FIXED: Bubsy has corrupt graphics - it required register $4210 bit 7 to
  trigger at the end of h-blank of line 224, not at the start.
o FIXED: Jurrassic Park locks with sound enabled. (Corrupt ROM image).
o FIXED: Q*Bert 3 has major graphics problems after 3rd level or locks. With -h 120
  and VAR_CYCLES game has corrupt graphics, otherwise it crashes. - ROM image
  is corrupt as same thing happens on a real SNES.
o FIXED: Evo - Chapter 1 title page shown on two backgrounds at same time -
  not bug just sub-screen addition being used.
o FIXED: Ghosts and Ghouls needs H-DMA to be enabled if register is written after
  start of frame - Super Punchout needs the opposite... -
  only start H-DMA if enable register written to during v-blank or h-blank.
o Exhaust Heat might require scanline drawing just before H-DMA rather than
  at end of h-blank.
o FIXED: Exhaust Heat has mode 7 offset problems. v0.24 accidentally fixed the problem
  but now its back again.
o FIXED: Goal locks at start with sound enabled. - The SPC700 seems to need to
  start executing instructions before the 65c816 so it has initialised $2140
  to $BBAA before the '816 checks for that value.
o FIXED: Final Fight 3 crashes with BRK instruction. - corrupt ROM.
o FIXED: T2 - has problems with clip windows.
o Robocop v Terminator: screen flashes like Alien vs Predator.
o FIXED:Nhl97 crashes - sound APU problem ?
o FIXED: Nhl97 now doesn't crash, instead the game won't start after the teams have
  been chosen.
o FIXED: Shadow Run shows sprite-sprite priority problems.
o Alien vs Predator uses colour subtraction on sprites but only on palettes 6-7?
  (Collect cloaking device, second object).
o NMI might need to be delayed to end of line.
o JanjYu Gakuen 2 looks at bit 6 of $4211 - might need to show source of
  IRQ - $40 for V-IRQ and $20 for H-IRQ?
o FIXED: Sunset riders has repeated background problems(?) - could be sub-screen
  addition/subtraction. Colour palette changes during game.
o Priority on snestest.smc Character Test are incorrect.
o Clay Fighter 2 writes to $3007-8 and reads from $3211-4.
o FIXED: Shien The Blade Chase tests bit 0 of $4200 until it goes 0 - reading
  $4200 must reflect joypad reading status. No, actually $4200 is open bus.
o FIXED: NBAJam (not Tournament Edition) has an odd memory map - accesses 
  code at $3Dxxxx. (corrupt ROM image).
o Super Bases Loaded uses Mode 5 and the background offset mode.
o FIXED: Super Bases Loaded 2 has an odd memory map: writes to $E00000 and reads from
  $E04000! (DSP1 chip)
o PilotWings uses a DSP.
o FIXED: Return Of Double Dragon needs -FL -ss 1 -o.
o FIXED: Tazmania is rewriting the colour palette just before the end of the frame.
  Shows up a a flashing screen. Uses software not DMA.
o FIXED: Actraiser2 has screen flash/timing problems. Was rewriting H-DMA
  start addresses during a frame - real SNES seems to ignore these.
o Actraiser2 uses mode 7 fixed colour palette mode - "32K" mode.
o FIXED: Agmawo locks at start. corrupt ROM - looks to be only first part of a
  multi-part ROM on the CD.
o FIXED: Alfred Chicken needs -FL.
o Mighty Max and Addams Family 2 are very slow with sound enabled.
o Williams Arcade Classics plays sound samples by varying the volume level
  using the gain control...
o FIXED:Zoop: Sound works initially but then stops during game.
o FIXED:Lion King locks up with sound enabled...
o Sparkster has lots of sound repeat problems.
o FIXED: Killer Instinct shows corruption at top of screen during the actual fight.
  Seems to need sub-screen emulation turned on.
o Look into passing mask into StartHDMA so the routine only resets DMA
  channels with the bit set in the bit mask.
o FIXED: RPM racing uses mode 5 512x512.
o FIXED: Biker Mice From Mars (sfbiker) needs -N and flipped layering '8'.
o FIXED: Mario and Wario (sfmarwar.smc) needs a mouse.
o Battle Toads: Double Dragon needs the -h parameter set to 100.
o FIXED: SF8752.smc has sprites problems when using tile-redraw code.
o FIXED: NHL '97 does a JMP $4320 in bank $87 - $4320 is a register area in that
  bank.
o FIXED: Chuck Rock has corrupted sprites on the title screen.
o FIXED: War of the Gems crashes with a STP instruction - bug in asm version of
  CPU core - appears when status register spliting was added. Snap6.
  If IRQ pending after returning from an NMI then incorrect status pushed
  onto stack.
o Adventures of Batman & Robin (bat.smc) has really slow music on title
  screen with SPC700 shutdown enabled.
o Return of the Jedi has lots of sound problems.
o WORMS has vertical offset problems on BG1 when displaying life bar at top
  of screen.
o FIXED: Street Racer has corrupt sprites on the player select screen.
o FIXED: Super Bases Loaded 1 uses Mode 5 (512x224) on intro.
o INFO: Batman Forever uses sub-screen addition with bg's being on both the main
  screen and sub-screen.
o INFO: Intro of Beavis and Butthead uses sub-screen addition with bg's being on
  both the main screen and sub-screen.
o INFO: ebreaker.smc bg's on both main and sub-screen.
o Big Sky Trooper's music is very slow.
o FIXED: Bomberman 4 needs -FH.
o FIXED: Captain Commando is interleaved.
o FIXED: Crystal Bean locks at start and is interleaved. - corrupt ROM image.
o Jim Power (jimp.smc) has scrolling/H-DMA problems on the intro.
o FIXED: Ogre Battle has fixed colour subtract problems on the main screen.
o pacman and Jim Power intro seem to rely on maximum number of sprites on a
  scanline at once to hide unwanted sprites.
o FIXED: Pacman 2 has scrolling/H-DMA problems during the game.
o FIXED: Power Drive (snk_powd.smc) uses 512x448 on intro.
o FIXED: SKI PARADISE (skiparad.fig) uses mode 7 priority per pixel
o The Magical Quest (smmouse.smc) has an intro with bad raster glitches - uses
  exact CPU timing!
o FIXED: Madden 96 needs -FH and has new Antherox intro.
o FIXED: College Slam (collslam.1 on CD) thinks non-standard controllers are 
  connected. It writes $12 and $02 to $4016.
o The sound on Speedy Gonzales sounds out of tune - seems to vary the
  frequency a lot - first low byte then the high byte.
o Stargate has sound clicks on channels 5 and 6 on title page.
o FIXED: Ranman1/2 Part 1 (ranma121.smc) crashes SPC700 at start up - looks like a
  65c816 addressing mode/instruction bug! - corrupt ROM image.
o Speedy Gonzales starts a long DMA to $2180 at v-line 1 with the screen not 
  blanked.
o FIXED: acc-elf.smc works on v0.1 but crashes with a STP instruction in v0.24.
o FIXED: FLYING HERO BUGYURU flyhero.smc does not work and image is odd size so code
  doesn't detect header and remove it.
o FIXED: Yaiba (lmk_yaib.smc) locks waiting for an interrupt to occur to no interrupts
  are enabled.
o CORRUPT ROM: Rise of the Robots does a long DMA to V-RAM during in the NMI handler -
  it might require the DMA to automatically stop when H-DMA starts if the
  screen is not blanked.
o FIXED: Andrew Agassi Tennis has missing sprites - only writes to low byte
  of sprite write address register. Writing to low byte must clear hi-byte as
  well.
o FIXED: Bonkers locks sound enabled. SPC700 code expected KOFF DSP register
  to return value just written.
o Mario Kart has odd graphic windows settings when first started.
o FIXED: Street Racer has odd size sprites and has missing tiles when displayed.
o FIXED: ASM 65c816, Aladdin keeps warping to other side of screen on first level.
o The Great Circus Mystery (circusmystery.smc) doesn't work.
o James Pond 2 gets stuck waiting for SPC700 to respond after first title
  screen. works on v0.24.
o Mario All stars - Super Mario 2 uses mode 2 (offset per tile) but with
  height 64 on bg #2. Black screen.
o FIXED: Chrono Trigger uses mode 2 with width 64 for wavey 'Trigger' text. Text
  should scroll onto screen, it doesn't. It does if width 64 is disabled,
  but it starts on the screen first. - bug with not wrapping Quot variable
  with mode 2 width 64.
o Tetris Attack uses screen screen height of 64 on offset-per-tile mode 2.
o Batman forever might show that if OBJs are on both the main and sub-screens
  and colour addition is enabled, then only OBjs with palette numbers
  4 or greater take part in colour addition and are not displayed on the
  sub-screen.
o FIXED: CPUShutdown causes problems for ROMs that wait for h-blank using $4212
  during the v-blank period - Reschedule doesn't enable HBLANK_START_EVENT
  during the v-blank period so the cycle skipping code doesn't wake up the
  CPU until h-blank end.
o FIXED: Putty Squad seems to use wrong palette for each tile when mosaic effect
  is being used - could be only the ROM so far with 16x16 pixels tiles and
  mosaic effect.
o FIXED: Mortal Kombat 1 restarts level when once the 'fight' message has disappeared.
  - 0.31 has problems.
