Homebrew SnemulDS Compatability CFG file update Thread

So recently i have obtained a DSTWO now odly enough the games on the SNES emulators run mostly at half speed frames per second (30 fps). Snemulds though focusses on running games at full speed (60 fps)and smooth. Now the only problem is this sacrifices some compatabilty errors, graphic glitches etc.
(What i dont understand is why DSTWO SNES doesnt use Gladius SPC Sound Core its almost perfect and would no doubt speed things up there)

Good news though. With Snemul there is a ton of options you can play with to get a game running perfectly or near perfect. Since its release suprisingly no one has made a thread focused on the snemul.cfg file only a couple rough compatability lists here:
and here:

Now im creating a thread for the cfg file specifically to update it which i will post once this gets going if i have enough help cause lord knows everyone wants to play SNES and smoothly.

NOTE: This thread will be based on SnemulDS Beta.
Also do not use external ram it only helps in rare cases.

Also a couple tips to get you going edit the snemul.cfg file and change these lines

Set your rom path where you have your SNES games are on your card like this.


When you have a game working perfecly or near perfect list it in this fasion so you can add it to the cfg file:

SpeedHacks = 1
#BGPriorities = 1
# Mario is transparent in level selection
Transparency = 0
BG3SSquish = 1
YScroll = 24
Vblank = 1
Sound = 1
Scaled = 0
BGLayers = 10111
BGPriorities = 0
AutoSRAM = 0

I will try and keep a master file up to date, please dont forget to save your settings in the menu once you have it working well with no or little graphical errors and running close to %100

NOTE 2 : SnemulDS is compatable with any flash card and this thread is for that purpose without using a DSTWO and getting half the fps on their SNES emu's but good graphic compat.

SnemulDS skinny on how To use:

Load Rom: Pick game from target folder
Save State: Save game at the point your at
Load State : Load game from last saved point
SPC Jukebox: Play spc file (SNES sound files found free and distrubted on the interned) Use Moonshell 2 instead

Options menu:
  • Normal Speed - Regular speed trying to get 100%
  • Fast Speed - Faster PPU may be needed run speed of games faster
  • Normal - No speed hacks
(Note always when trying to get a game running best use this with Normal or Fast before loading the game as it will emulate properly without cutting out some things sometimes needed for speed)
  • Cycles - Cut out unneeded Cycles (Best to use as it usually only affects unneeded cycles)
  • Interupt - Same but uneeded Interupts (Can cause glitches)
  • Full - Both at the same time (Same)
--Screen Layout:
  • Pretty straight forward, HUD: Squish status bar ect. , Yscroll: Where to place screen as it only has 192 pixels and games are 224, Scaling: Good to use on side scrollers as screen fits horizontally options: Medium (208 pixels squished with full sprites) Full (All 224 Pixels squished)
--Backgrounds and Sprites:
  • Good to leave on automatic though you could cycle through options of numbers (rarely improves games) or presets (sometime there is a better one than auto picked)
Advanced Menu:

--Reset: (restart game not same as loading from start if you want to load without hacks)

--GFX Config: (If you change things hit the Fix graphics button or enter new area)
  • Priority per tile: (set to make a background layer (there are 4) a higher priority, might be good to change to fix gfx mess either default None or to priority BG1 or BG2)
  • Block Priority: (Either on or off) Sometimes works better On sometimes fixes gfx mess set to Off
  • Blank Tile: (You could play around with this i dont usually sometimes set to higher numbers helps)
Under Automatic Ordering:(Leave on Usually picks best fit)
  • BG0
  • BG1
  • BG2
  • BG0(Low) - Again all these numbered options places priority, if you cant get a game working without gfx mess you could play around with these)
  • Sprites 0
  • Sprites 1
  • Sprites 2
  • Sprites 3 - Same thing places sprites (hero whatever) in different priorites you could play around with this if you want
Note: Seems that most games suffer the problem of the sprites always having priority and standing above some BG layers sometimes. (If you find fix post)

That should be all you need to know to get games running
