HyperDS runs a few of my demos. It has a very nice front end. It's a pity I can't get hold of a newer version for testing, because I think it would probably do quite well. This is the list of what does something: cube_emu : works with a lot of flashing dsmode4ep : produces some strange colours first1 : works ship_emu : starts running in blue, then a bunch of graphics error messages texture_emu : works - sideways tri_emu : works - wrong colour I'll try to describe it. You can choose a screen size of 320x240 or 640x480. Strangely, only one of the screens has been emulated (the top one). Menu: File - Load - Binary - (choose a file) File - Exit Options - Frameskip - (various) Options - Show - OSD Options - Zoom - 320x240 or 640x480 Options - Configure - (see below) Emu - Resume / pause / reset / Step View - (debug options see below) Tools - Screenshot Help - Check for Update (greyed out) Help - About The debugger has these views: Disassembler, memory, Processor, Log, Cheat Finder, Palette, Sprite, Graphics. I know nothing about this, but it all appears to work. The Options - Configure opens a new window that lets you set up the Keyboard, Joystick/Gamepad, System bios and sound, User Interface - choose Splash Screen on/off. The Keyboard and Joystick/Gamepad screens have a lovely picture of the DS showing exactly where each button is, and what Key or Button has been assigned to it. HyperDS is certainly the nicest-looking of the emus. It's a pity it doesn't do much. I can post a picture if anyone is interested.
