PC-Engine/TurboGrafx-16 emulator for NDS

This is a PC-Engine/TurboGrafx-16 emulator for the Nintendo DS(i)/3DS, it can also emulate some of the (Super) CD-ROM^2 & Arcade Card. It does not emulate the SuperGrafx. All games are not perfect. Don't use overdumps as these are evil on PC-Engine.

1. Create a folder named "NitroGrafx" in either the root of your flash card or in the data directory (eg h:\NitroGrafx or h:\data\NitroGrafx). This is where settings and save files end up.
2. Now put your games into a folder where you have (PC-Engine) roms, max 768 games per folder, filenames must not be longer than 127 chars. You can use zipped files (as long as they use the deflate compression).
3. Depending on your flashcart you might have to DLDI patch the emulator.

The GUI is accessed by pressing L+R (shoulder buttons) or by touching the screen, tabs are changed by pressing the L or R button, going to the left most tab exits the GUI. Closing your DS puts the emulator in sleep mode, just open it to resume.

When you first run the emulator I suggest you take a peak through the options and change the settings to your liking and then save them. To be able to use CD-ROM games you have to select a CD-ROM System rom (bios) from Options-Machine-BiosSettings-SelectBios. You can use .iso files or .bin/.cue files see CDROM_readme.txt for more info.

Now load up a game and you should be good to go.
