o INFO: Aero the AcroBat 2 might wait until a bit in $420B (h-dma enable) clears -
  does reading that register indicate H-DMA channels in progress?
o INFO: Alien vs Predator uses colour subtraction on sprites but only on palettes 6-7?
  (Collect cloaking device, second object).

o FIXED: Mighty Max uses colour window on main screen to clip background colour
  palette changes - except its not working on Snes9x.
o FIXED: Batman - revenge of the joker locks at start - waiting for SPC700 which
  has hit a stop instruction.
  - has its ROM header information in the wrong memory location, fooling Snes9x
    into thinking its a HiROM; it isn't.
o DONE: T2: Arcade Game displays multi-coloured blocks of tiles when a mode 3
  screen is being displayed. Screen shown when game-over.
  - Corrupt ROM.
o DONE: WWF-Super Wrestlemania and WWF-Raw both seem to display junk background
  layers - the ROM enables the layers but does not set up any background data.
  - not a problem.
o DONE: Ardy Lightfoot and Oblix both flash the sprite of the main character
  on and off every other frame, should they do this or is it a bug?
  - Corrupt ROM.

  level map screen.
o DONE: NMI might need to be delayed to end of line.
  - no, but it did need delaying for a few microseconds.
o FIXED: Pilot Wings tries to set up a V-IRQ to happen on the line its already on,
  uses IRQ to switch to mode 7. -h 120 fixes problem. Cycle timing must be
  off.
o FIXED: Jim Power (jimp.smc) has scrolling/H-DMA problems on the intro.
  - missing mode 2, offset-per-emulation and then offset data for first tile
    was being ignored.
o FIXED: Captain America has single pixel high line corruption through some of its
  tiles.
o FIXED: Winter Gold causes ZSNES Super FX code to overwrite the static data after its
  allocation - was causing the X library to crash since that was the .o after
  linked after zsnes.o.
o FIXED: Bugs Bunny has sound repeat problems when Bugs kicks a dog. - not a problem,
  just needs -envx.
o FIXED: WWF-Arcade crashes - calls a subroutine at address $EE758D which only 
  contains zeros at that address. Memory map bug?
  - Corrupt ROM
o FIXED: -frametime option is broken.
o FIXED: Start screen on Chase HQ is corrupt. v0.24 has same problem.
  - needs CentreX & 1023 on mode 7 when screen repeat is on.

  the sub-screen. Should it be either the fixed colour or back-drop
  colour get added instead?
  - fixed colour should be added.

  on orcid practice level - colour window invert bug?
o FIXED: Killer Instinct bg #1 is hidding some transparency effects and the
  fighter's sprite shadows on some levels.
o FIXED: Mario All stars - Super Mario 2 uses mode 2 (offset per tile) but with
  height 64 on bg #2. Black screen.
  - real problem was that horizontal offset per tile wasn't implemented.

  using the gain control...
o FIXED: Bomberman 5 flickers on title screen when H-DMA is enabled.
o DONE: Exhaust Heat might require scanline drawing just before H-DMA rather than
  at end of h-blank.
  - looks like the game just needs -h 110. Cycles per scanline count might be
    too small for all games.
o FIXED: The Magical Quest (smmouse.smc) has an intro with bad raster glitches - uses
  exact CPU timing!
o FIXED: Big Sky Trooper's music is very slow.
  - must have been a CPU shutdown problem.
o FIXED: Micromachines 2 has continuing engine noise problem when race is over -
  sound channel 7 is in sustain mode with time period set to infinite.
  - must have updated ADSR parameters as the it was in progress.
o DONE: Check Micromachines on real SNES - does the Ocean logo shear at the start?
  If it doesn't it could be a bug in the mode 7 code - the same problem that
  affects battle racers. - Does the same thing on a real SNES.
o FIXED: LAMBORGHINI AMERICAN has lots of missing music notes -
  uses bent-line inc with attack rate of infinite?
  - S9xSetEnvRate thought that the channel was silent and hence the number of
    volume steps was 0 so erate was always being set to 0.
o FIXED: Ninja Warriors has missing graphics on the title screen - V-IRQ problem?
  Problem appears after v1.16. Didn't like H-IRQ triggering on the same line
  if the H-IRQ position register was updated.
o FIXED:Pac-in-time title music sounds a lot worse with new envelope sound code in
  1.17. The game requires samples to be keyed on without being keyed off first.

o FIXED: Find out why graphics are all squashed up on sensi soccer/ bman with old
  old tile drawing code...
o FIXED: IRQ wobble on Aladdin at top of screen - causes occational palette flash.
o FIXED: 7th Saga, Actraiser2 and Addams Family causes a core dump on exit.
o FIXED: aleste.smc has sprite display problems on title screen on tile-based redraw
  code.
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

  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

  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 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 FIXED:Nhl97 crashes - sound APU problem ?

  $E04000! (DSP1 chip)
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.

  multi-part ROM on the CD.
o FIXED: Alfred Chicken needs -FL.
o FIXED:Zoop: Sound works initially but then stops during game.
o FIXED:Lion King locks up with sound enabled...
o FIXED: Killer Instinct shows corruption at top of screen during the actual fight.

o FIXED: Mario and Wario (sfmarwar.smc) needs a mouse.
o FIXED: SF8752.smc has sprites problems when using tile-redraw code.

  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.

  addition/subtraction. Colour palette changes during game.
o FIXED: Street Racer has corrupt sprites on the player select screen.
o FIXED: Super Bases Loaded 1 uses Mode 5 (512x224) on intro.

  connected. It writes $12 and $02 to $4016.
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 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 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 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 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.

  0.41. H-DMA?
o FIXED: Contra 3 has clip window problems resulting in black screen, only
  OBJs can be seen when game first starts.
o FIXED: YUUYUU TOKUBETUHEN (yuyut.smc) has missing OBJs when screen is split -
  it enables both clip windows on OBJ and sets the combination mode to
  AND but both clip windows only overlap a few pixels so the OBJs are not
  displayed. - bug in window code, needed to flip the logic window
  combination mode because the window area add already been flipped.
o FIXED: XOR window clip code is producing bands that overlap.
o FIXED: TOKIMEKI MEMORIAL (tokmemor.smc) displays corrupted sprites - every other
  group of four pixels is missing.

  timing problems? Missing NMI - ROM kept turning NMI enable flag on and off.
o FIXED: Firemen locks at start waiting for SPC700. Human game, needs -ratio 3.
o FIXED: Battle Toads: Battlemanics crashes during intro - ROM's NMI handler does not
  switch index registers to 16-bit before pushing them onto the stack, but
  always switches them to 16-bit mode when restoring them.
  NMI timing problem.
o FIXED: Contra 3 has missing fire effects when bomber plane drops bombs - use
  freeze-game to see. - Colour window is fully clipping the sub-screen and
  the fire effects are only on the sub-screen.
  - colour window invert bug.
o FIXED: Illusion of Gaia uses sub-screen subtraction with half flag during game
  select. Also, uses colour window to cut a hole in the main-screen,
  should the sub-screen be visible at this point? Only two backgrounds are
  being displayed, one on the main-screen and one on the sub-screen and
  the sub-screen is not being added to the background only the background on
  the main-screen.
o FIXED: Empire Strikes Back needs -ratio 5 to work.
o FIXED: llusion of Gaia menu on the first screen should be on a dark background.
  ZSNES gets it correct.
o FIXED: Commodore 64 emulator doesn't work with asm CPU core - works fine with
  C code.
o FIXED: Chrono Trigger: crash bug in clipping code - use snapshot F6 and press 's'.
  Corrupts stack causing crash.
o FIXED: Toy Story only updates screen every-other frame and woody flashes 
  continuously. (Woody flashing is due to hacked ROM)
  Toy Story requires NMI to happen immediately after a WAI instruction.
o FIXED: Tales of Phantasia executes across a 0x8000 boundary and either side of
  the boundary are at different offsets into the ROM. Causes a crash.
o FIXED: Itchy & Scratchy has sprite corruption on the one of the title screens.
  Problem appeared between v0.4 and v0.41.
o FIXED: King of the Rally has missing music on the car-feature selection screen.
  Works in v1.00. Requires DP+X addresses to wrap in zero page.
o FIXED: (again) Lufia I locks when shutdown is enabled, waiting for SPC700.
  made the SPC700 wake up if the 65c816 reads from the one of the 4 comm ports.
  The SPC700 used to only wake up when the 65c816 wrote to the ports.

o FIXED: Mighty Max and Addams Family 2 are very slow with sound enabled.
o FIXED: Yoshi's Island might show there's an 'off-by-one' bug in the clip window code
  when it pops up a message box.
  - bug with clip window 2 'outside area' setup code - window 1 code was correct.
o FIXED: YS 5 - text boxes should contain a smooth colour change; they don't.
  - Colour addition/subtraction code and halve the result shouldn't halve the
    result if its only the fixed colour.
o FIXED: Modes 2 & 4 are broken - horizontal offset per tile rendering is incorrect.
  Multiple tiles have to rendered in the same tile box.
o FIXED: Yoshi's Island PAL - ZSNES freeze state. Level 6 boss. Mode 2 offset per
  tile problem.
  - tile offset data has to take into account horizontal offset of background
    layer.

  problem, has attack rate of 10ms, decay 1200ms, infinate sustain and a
  sustain level of 5.
o The Lion King: under sound test, continue long song contains some odd 
  sounding notes. Is a particular type of sample not being decoded correctly?
o Clicks on the title music of Madden 98.
o DOREMI Fantasy milon uses decay exponential volume envelope on the notes at
  the end of the title music - they seem to take too long to decay.
o NHL STANLEY CUP locks at start waiting for the SPC700 - works with sound
  disabled.

  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: Bugs Bunny has junk snow characters on bg #1.
  - initialisation problem/timing problem. If you wait until the joypad screen
    is displayed, then start the game, it works!
  Was doing junk H-DMA into V-RAM write registers.

o DOS port can't load some ROMs from CD. NLKE has same problem. Allegro?
  ZSNES loads most of them fine.
o RPM Racing doesn't display correctly when interpolation and 16-bit screen
  mode. X11 port. Works when full-screen X.
o Airwolf hacker intro is very corrupt - corrupt ROM?
o Super Bases Loaded uses Mode 5 and the background offset mode.
o Look into passing mask into StartHDMA so the routine only resets DMA
  channels with the bit set in the bit mask.
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 Priority on snestest.smc Character Test is incorrect.
o Shien The Blade Chase tests bit 0 of $4200 until it goes 0 - reading
  $4200 must reflect joypad reading status.
o Sailor Moon has colour window problems during intro of game.
o Sailor Moon R screen flashes black during game. -h 102 fixes.
o Tile corruption on Super Pang on 3rd level+ - only on DOS port.

o Wile E's Revenge has missing music, and very quite sound. Also displays 
  rotated mode 7 character picture during titles.
o Top Gear 3000 sits in a loop waiting for the H-DMA line count register
  to reach a particular value - it never does because its not emulated yet!

o Live a Live locks up.
o Flashback - 3 Lanugage version keys off then on all 8 sound channels 
  repeatedly while the menu is being displayed (select button) during gameplay.
o Alien 3 - junk line displayed after intro has played - bg #3 is showing
  junk tiles but is being mostly clipped by graphics window.
o All Japan Pro Wrestling performs an extra long DMA (20480 bytes) at scanline
  223 and relies on the real SNES to terminate the DMA when video refresh DMA
  starts at scanline 1. This doesn't happen on Snes9x and V-RAM gets junked.
o Jikkyo Power Pro Wresling sprites glitches on the second demo wrestling
  match. Settings %'age cycles per scanline to 103 fixes problem.
o Shijou Saikyou no Quiz Ou Kettei Sen Super glitches on the mode 7 intro
  screen.
o SHOUGI MARJONG intro theme music sound slighty off key.
o Ogre Battle (US) - Junk line/graphics displayed on first few screens.
