The Saturn emu right? how does it work? I mean, is just a "normal" use or it does tricks like actually emulating one of the SH2s in a core and the other in the 2nd core?
Yep, and I can only assume it does 1 SH2 per core, or the SH2s on one core and the VDPs\SH1 on the other. I don't really know, as the developer doesn't seem to speak English (well).
1) Older PCs weren't usually dual core, when these emus were written. 2) They don't need it. Dual core can be hard(er) to implement, so it's only usually put in when the performance benefit is justified and when the system being emulated in multicore.
well .. those points I am aware of but: cant someone use one core to do R4300i and RCP on the other core? wouldn't it be more accurate than D3D? A saturn emulator comes to mind when discussing about multiple cores.
Yeah but why? N64 emulation is already perfect even on obsolete computers:nod: But that may work in the GP2X which has a dualcore ARM9.
Sure if only RSP/RDP were hand emulated LLE style insted of HLE. Other then that it's very difficult to make N64 work across two cores. GP2X will never emulate the N64 and it all has to do with the lack of FPUs. There is no way you will get any considerable framerate with out an actual FPU. PSP is saved by the fact it is not only mips but has a FPU.
Just to update this thread, I've been playing with the JXD 301 for over a week now and can say it's not exactly what I expected but it's not all that bad! Movies en Music run well as expected, normal divx/xvid movies of around 700 meg work fine (allthough widescreen movies are not automatically resized to fullscreen nor can it be set manually as far as I know and this makes the movie even smaller but still ok) Games: well this is the main problem with the jxd, nice all those emu support on the box but they all (well as expected actually) have some kind of drawback except for the NES and most important Neo Geo - NES: works fine. - SNES: works fine but the sound of most games is a little messed up (goes too fast) besides that all games run at fullspeed and fine (excluding the FX games, they are rather slow) - Sega MS/MD: run fine without the sound on, with the sound on some delays/slowdowns are noticable, and believe it or not the european roms dont play with the message they were not designed for the jp MD lol. - GBA: many games crash or have other weird effects, some play so so. - Neo Geo: only supports .neo extentions, these are really hard to come by but I eventually managed to get my hands on a few, they run great! Anyway, for the price I can't really bitch too much.. I like the size love the screen, the sound is good and it helps me kill time on my way to work, just hope they will fix some issue's with a new firmware release.. I got mine from ebay for 90 euro (including shipping to holland from HK)
Found it being sold in MercadoLivre. (R$ 580 = 330 US dollars) Check the auction, there are lots of pic: http://produto.mercadolivre.com.br/MLB-65327386-_JM
This player looks like the generic units i've seen all over China. Just better form factor. In regards to the emulation, perhaps someone could elaborate a bit more, such as configuration options (I assume no button reassign possible), quality, speed, etc. Odd, since all the videos I've seen seen show the snes music playback as being just fine.
Actually some play somewhat fine, but most sound weird as the sound runs faster then normal. As for button reassign, there is an option while playing a snes game named 'set keybord' all the buttons are defined and the is a restore default option too so it looks legit, but i have no clue yet how to change the settings.. tried all the buttons but nothing seems to change.. (could be me) maybe somebody else can shed some light on this?
I'm somewhat impressed that the emus run as well as they do on this system since guys on mp4nation have pretty much figured out what GNU emu source they stole to make the emus. I think once the homebrew scene figures out how to run code on the unit proper ports will be made.
Would suck if keys can't be re-assigned. Some consoles use more than 4 buttons, and some configs are more suitable for diffrent games (eg. KOF for neo geo).
While playing Neo Geo games the set keybord option is not available, looks like only snes has this 'option' that seems not to work too.
Battery life could be better too, while playing games or watching a movie the battery goes fast (2 or 3 hours max I guess)
Really curious about the music speedup. perhaps if there is enough intrest you can make a recording or video of what your experiencing.
