TODO :
- ffight2b: Dipswitches ($7eadd7 ?)
- sblast2b: Dipswicthes
- kiinstb: Fix gfx glitches and missing texts

WIP :
- 0.137: Fabio Priuli simplified the SNES drawing routines, added support for offset-per-tile, cleaned up the code, fixed remaining issues in hires modes, fixed serial joystick reads and slightly simplified palette handling. Added very preliminary driver_data class for snes based drivers (it only contains input-related items for the moment, because these are needed to add support for additional controller types in MESS). Fixed scrolling problems. Refactored joypad inputs to be consistent with other input devices (used in MESS). jbo_85 fixed Offset-per-tile graphics. jbo_85 andf Fabio Priuli fixed OAM overflow.
- 0.136u4: Minor SNES refactorization. Temporarily reverted implementation of mult/div through timers since it breaks some SNES games on the MESS side [Fabio Priuli].
- 0.136u3: SNES wip [Fabio Priuli]: Added a couple of registers to snes_ppu struct. Moved color blending (background & subscreen color addition/subtraction) at the end of the drawing process. Removed some unused (and not working anymore) debug code. Fixed the remaining debug functionalities. Moved colour struct to be another layer (simplifying some code). Updated hires blending to work with two pixel at time. Fixed clipmasks with hires modes. Added dipswitches 'Browse tiles' and 'Browse maps'.
- 0.136: Hardware multiplication and division on the SNES takes 8 machine cycles to complete [Wilbert Pol].
- 0.135u4: Fabio Priuli moved SNES timer allocation to MACHINE_START.
- 0.134u1: Angelo Salese fixed SNES CG ram reading address and an incorrectly SNES setted DMA register read, fixes DMA Memory in the test cartridge.
- 0.133u4: SNES improvements [Angelo Salese]: Fixed half colour blending behaviour.
- 0.133u3: SNES Updates [Angelo Salese]: Fixed direct color gfxs in mode 7. Fixed direct color gfxs in mode 3/4. Fixed a vram out-of-bounds bug. Fixed a blending bug involving main/sub color maths. Fixed interlace mode gfxs when not in gfx modes 5/6. Fixed a GDMA boundary bug. Made the OAM address reset more accurate. Fixed HDMA mid-frame inits. Added clip colors to black window function. Converted color clipping to use struct entries. Made dynamic H resolutions to be called only at vblank start and and fixed gfx mode switching 1/5 and 5/1. Made the gfx mode switches more accurate. Corrected a bunch of SPC registers behaviour. Improved joypad read/write handling and fixed a serial port quirk. Fixed serial port for player 2 as well. Improved cart mode 20 reserved access behaviour. Added OBJ interlace support.
- 0.133u2: SNES video updates [Fabio Priuli]: Re-enabled video debug functionalities in debug build (to toggle background layers). Added proper priority tables for various bg/obj layers. Largely simplified tile and line drawing routines, and fixed small bits here and there. Further simplification of tile drawing routines. Added palette index to 8bpp tiles (correct color_shift still unsure, though). Reworked video drawing routine to simplify the various graphic mode drawing and to allow proper implementation of priority orders (especially bg3 priority bit and mode 7 priority order). Improved mode 7 extbg (still missing mosaic). Added some more debugging options. Improved Mode 7 math precision (but still some issues remain) and added a few elements to PPU struct. Implemented Mosaic in Mode 7. Merged OAM functions. Added a few elements to PPU struct (this might be handy if we ever come to convert SNES PPU to a device). Fixed Mode 7 shared scrolling/matrix registers. Slightly optimized Mode 7 math (by using Anomie's recursive formula). Moved some more register contents to PPU struct. Added PPU1/PPU2 Open Bus support, STAT77/STAT78 registers should be more accurate (even if still not perfect). Simplified window masking code and moved some more regs to PPU struct. SNES fixes (mostly MESS specific) [Angelo Salese]: Fixed Super Kick Boxing booting and sound (audio\snes.c). Preliminary open bus emulation for allowing Shien's Revenge / Shien the Blade Chaser to boot. Fixed mode 5/6 bg drawing cutted in half bug. Fixed (presumably) broken gfxs in nss_sten. More accurate behaviour of the last scroll register. Improved mode 5/6 gfxs when tile size = 16x16. Fixed rowscroll line bugs in many games. Made the unsupported reads on I/O open bus, fixed a layer enable in Super Kick Boxing. Fixed vram size when in hires mode. Hooked up interlace mode. Fixed doubled y-axis sprites when in interlace mode. Improved window effects when in H-512 mode. Removed a kludge with color windows. Fixed buggy layer clearance when in H-512 modes. Fixed the x scrolling wrap around bug when hscroll == 0. Fixed a bug that were causing a row of corrupted tiles during scrolling situations. Fixed irq ack and fixed TIMEUP register open bus behaviour. Even more aggressive open bus fixes. Fixed a partial update bug when the screen is in interlace mode. Fixed 8bpp layer colors.
- 0.133: Several MESS-specific SNES fixes for rendering [Angelo Salese].
- 0.129u1: Atari Ace made all SNES obc1_, DSP1_ and DSP2_ exports static.
- 0.127u7: Tomasz Slanina fixed problem with OAM address reset at start of vblank (machine\snes.c). Fabio Priuli and Byuu added emulation for SNES special chips DSP-2 & OBC-1: Added sources snesdsp2.c & snesobc1.c. Removed special chips detection from MAME. Modified memory handlers to account for the new chips.
- 0.127u6: Fabio Priuli changed the NSS/SNES loading code to support more cart/memory layouts and generally be more in line with the MESS way of handling SNES cartridges. Also some minor NSS/SNES cleanups.
- 0.126u5: Changed kinstb.c to snesb.c driver.
- 0.108u5: Added kinstb.c driver.
