4-29-2008 A Neo-Geo emulator for the Nintendo DS, as its the first release here's all the info you'll want: - Currently emulated: - M68000 cpu (cyclone) - Z80 cpu (DrZ80) - All forms of NeoGeo protection/encryption - Graphics - ADPCM audio - PSG audio Not emulated: - FM audio - 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. USING THE EMULATOR Required: - Nintendo DS (lite) - DLDI compatible flash card First, you need to patch NeoDS.nds for your DLDI flash card (NOTE - not all flashcards require patching). See here: http://chishm.drunkencoders.com/DLDI/index.html. Please don't email me for help about this, there are plenty of places online that explain how this works. Next you will need to convert some NeoGeo roms (mslug.zip for example). You also need a bios rom (neogeo.zip). NeoDS uses the same rom sets as MAME, so make sure your games 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. 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. The rom should load, and you should be playing. 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! Controls: [Arrow keys] - Arrow keys [A, B, X, Y] - NeoGeo face buttons [Start] - Start [Select] - Coin The NeoDS gui is controlled with the stylus. - 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. This can actually make some games run faster! It is easier for NeoDS to emulate a slower cpu, and some NeoGeo games don't use the full cpu power anyway. Experiment and see. - Screen Off - The lower screen can be turned off. Touch anywhere to turn it back on. - Load rom - Load a new game ______________________________________________________________________________ 下載：http://0rz.tw/e844r 官方：http://groups.google.com/group/neods -- 李居明鄭百勝羅國璋曾智偵黃平洋黃裕登廖敏雄王光輝張耀騰洪一中陳義信涂鴻欽黃煚隆黃忠義呂明賜林朝煌陽介仁孫昭立王光熙謝長亨陳憲章林仲秋郭建霖郭進興郭建成 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 59.115.183.18
