This is a NeoGeo AES/MVS emulator for the Nintendo DS. It can run all types of NeoGeo roms with some limitations.
==Features==
* M68000 cpu (cyclone).
* Z80 cpu (DrZ80).
* All forms of NeoGeo protection/encryption.
* Graphics.
* ADPCM audio.
* PSG audio.


Currently emulated:
==Installation==
'''Note:''' To use this emulator, you will need to prepare the compatible BIOS ROM (neogeo.zip).


* M68000 cpu (cyclone)
Patch NeoDS.nds for your [[DLDI|DLDI]] flash card (not all flashcards require patching).
* Z80 cpu (DrZ80)
* All forms of NeoGeo protection/encryption
* Graphics
* ADPCM audio
* PSG audio


Not emulated:
Convert some NeoGeo roms (mslug.zip for example). NeoDS uses the same rom sets as MAME, make sure they work in MAME before proceeding. 


* FM audio
Put all the roms you want to convert along with the bios together in a folder. 
* Raster effects
* Multiplayer
* Some timings are not that accurate


FM audio has already been done in jEnesisDS, so it is possible in theory. It will be hard to squeeze it into NeoDS, as both the ARM7 and ARM9 are pretty busy.  But I will try.  Most of the graphics in NeoDS are drawn with textured quads.  Emulating raster effects using this method would require more polygons per frame than the DS is capable of (as far as I can tell).  It may be possible to emulate raster effects using the DS 2D hardware, but there are lots of reasons why this would be difficult.
Copy NeoDSConvert.exe into the same folder.   


==Installation==
Run NeoDSConvert, and it will convert all the NeoGeo roms in that folder. The converted roms will have the *.neo extension.


Required:
Copy the [[DLDI|DLDI]] patched NeoDS.nds, and all the *.neo roms into the root of your flashcard.
* Nintendo DS (lite)
* DLDI compatible flash card


Optional:
==User guide==
* Slot2 flashcard with RAM (Opera expansion, SuperCard lite, etc.)
* Run NeoDS.nds, the main menu should load, showing you a list of all the roms on your card.
* Use the arrow keys to select, and press start to choose a rom to load. You can load a rom without audio which will improve frame rate, but you won't get any sound (obviously).
* Once a game is loaded without audio, the only way to get audio back is to reload the game. Some games will freeze with audio disabled, so be warned.
* If you have a supported flashcard with external ram in the GBA slot (optional), NeoDS will use the extra ram to cache more data. This will improve the speed of some games, but is never required. The main gui screen will display the test SLOT2 if this feature is active.

This is a NeoGeo AES/MVS emulator for the Nintendo DS. It can run all types of NeoGeo roms with some limitations.

Features

  • M68000 cpu (cyclone).
  • Z80 cpu (DrZ80).
  • All forms of NeoGeo protection/encryption.
  • Graphics.
  • ADPCM audio.
  • PSG audio.

Installation

Note: To use this emulator, you will need to prepare the compatible BIOS ROM (neogeo.zip).

Patch NeoDS.nds for your DLDI flash card (not all flashcards require patching).

Convert some NeoGeo roms (mslug.zip for example). NeoDS uses the same rom sets as MAME, make sure they work in MAME before proceeding.

Put all the roms you want to convert along with the bios together in a folder.

Copy NeoDSConvert.exe into the same folder.

Run NeoDSConvert, and it will convert all the NeoGeo roms in that folder. The converted roms will have the *.neo extension.

Copy the DLDI patched NeoDS.nds, and all the *.neo roms into the root of your flashcard.

User guide

  • Run NeoDS.nds, the main menu should load, showing you a list of all the roms on your card.
  • Use the arrow keys to select, and press start to choose a rom to load. You can load a rom without audio which will improve frame rate, but you won't get any sound (obviously).
  • Once a game is loaded without audio, the only way to get audio back is to reload the game. Some games will freeze with audio disabled, so be warned.
  • If you have a supported flashcard with external ram in the GBA slot (optional), NeoDS will use the extra ram to cache more data. This will improve the speed of some games, but is never required. The main gui screen will display the test SLOT2 if this feature is active.

NeoDS GUI:

  • Video - Video can be normal or scaled. Normal is a cropped screen. Scaled shows the full screen, but scaled down to fit.
  • CPU Clock - The NeoGeo cpu can be underclocked. Experiment and see (it is easier for NeoDS to emulate a slower cpu, and some NeoGeo games don't use the full cpu power anyway).
  • Screen Off - The lower screen can be turned off. Touch anywhere to turn it back on.
  • Load rom - Load a new game.
  • Save - Write the current configuration and sram to the flashcard.
  • Input - Remap the input.
    • The input configuraiton screen is a grid. DS buttons are down the right side of the screen. NeoGeo buttons are along the top of the screen.
    • Each row of boxes coorisponds to one DS button. Putting a check in a box maps a NeoGeo button to a DS button.
    • You can map multiple NeoGeo buttons to a single DS button this way, which can be useful for fighting games, or for other things.

Compatibility list

A list of tested ROMS can be found in the discussion thread.
