'''NitroGrafx''' is an emulator for the Nintendo DS (NDS) that allows users to play games originally developed for the PC-Engine/TurboGrafx-16 console. In addition to emulating the original hardware, it also has the capability to emulate some (Super) CD-ROM^2 & Arcade Card games. However, it should be noted that not all games are fully compatible, with some US games not working due to encryption.

Select a CD-ROM System rom from Options> Machine> BiosSettings> SelectBios.
 
Select a .iso file or a .cue file from a bin/cue combo.
 
Press the Start button when the CD-ROM System screen shows up.
 
Right now NitroGrafx supports loose .iso files for games that only has 1 data track (or 2 where the last one is a backup), or bin/cue files for complete cd rips.

Also note that all games are not perfect (a lot of US games doesn't work because they are encrypted, use PCEToy or the emulator Ootake to decrypt these before you use them). And don't use overdumps as these are evil on PC Engine.

NitroGrafx is an emulator for the Nintendo DS (NDS) that allows users to play games originally developed for the PC-Engine/TurboGrafx-16 console. In addition to emulating the original hardware, it also has the capability to emulate some (Super) CD-ROM^2 & Arcade Card games. However, it should be noted that not all games are fully compatible, with some US games not working due to encryption.

To play these games, users may need to decrypt them using another emulator such as PCEToy or Ootake before using NitroGrafx. Additionally, it is important to avoid using "overdumps" as they can cause issues with the PC Engine.

Installation

Note: You will need to prepare the compatible BIOS images in order to use this emulator.

Download and extract file. Depending on your flashcart you might have to DLDI patch the emulator file.

You should also create a NitroGrafx directory either in the root of your card or in the data directory (eg h:\NitroGrafx or h:\data\NitroGrafx).

Put your games on your flash card, max 512 games per folder. Supports zipped files (uncompressed). Filenames must not be longer than 62 characters.

CD-ROM games can be in .iso or .bin/.cue formats.

User guide

Loading CD-ROM games

Select a CD-ROM System rom from Options> Machine> BiosSettings> SelectBios.

Select a .iso file or a .cue file from a bin/cue combo.

Press the Start button when the CD-ROM System screen shows up.

Right now NitroGrafx supports loose .iso files for games that only has 1 data track (or 2 where the last one is a backup), or bin/cue files for complete cd rips.

Known issues

The games that have severely lagging cutscenes tend to be the ones with major graphical errors, such as Emerald Dragon. One of the times I tested Mystic Formula tonight, the first in game cinema went at a perfect 60 FPS, but upon a fresh boot, went at the usual 55-58.

If you restart your DS, loading the savestate does not work. Savestate is only for the data, not CD audio position, but that's OK. Just don't do a savestate during a cutscene.

This emulator has come a long way in such a surprisingly short time! A large number of CD games are thoroughly playable, with only minor glitches in cinemas, and little to no slowdown.
