It must have been an enormous work to manually make a damn good optimized and fully working emulator for the GB© and GG! My respect
I tried your latest build but the sound on "Zelda: Oracle of Ages" and "Zelda: Oracle of Seasons" is still much to fast. |

I have done some optimizations and now my NES emulator runs at full speed on the MPx200 (without graphics shrink), so now to work on the graphics...
One problem I've discovered is the code which regulates the frame rate is not doing a good job when the machine is just slightly faster than needed. I will hopefully come up with a fix for this too. L.B. -------------------- the fastest instructions are none at all :)

Could you test the nes on a spvclassic?
I hope it will run better than other ness emulators

Download the new build (0.04) from the same spot:
http://www.bitbanksoftware.com/downloads/smartgear.zip I've integrated the NES code and done a quiick-n-dirty graphics shrink routine which isn't too ugly. The code is still a bit slow, so I still need to do more optimizations, but it runs quicker than SmartNES. With throttling off and frameskip on (30fps) it seems to run OK on my MPx200. Unfortunately the MPx200 with SP2003 is the only device I have to test on. The NES module supports the following mappers: 0, 1, 2, 3, 4, 7, 16, 19, 64, 65, 66, 68, 70, 87, 116, 160, 180 The graphics shrink routine needs to be changed. Currently it takes each 4x4 grid of pixels and turns it into a 3x3 grid with the following technique: 00 01 02 03 00 01 (02+03) 10 11 12 13 --> 10 11 (12+13) 20 21 22 23 (20+30) (21+31) (22+23+32+33) 30 31 32 33 Basically the pixels making up the right and lower edge of the 4x4 box are averaged with the neighboring pixels. Crude, but effective. I really don't think it's worth doing the shrunken graphics SMS or NES on the smartphone. It's hard enough to see the pixels on the phone when the image is displayed at 100% scale. I think the GameBoy and GameGear cover a large range of good games that make sense to play on the smartphone. Thoughts? Larry B. -------------------- the fastest instructions are none at all :)

Bitbank, great job. To tell you the truth, I LOVE the way SmartNES implemented landscape mode, I can hardly tell the difference from regular normal view. Maybe they don't do much mapping, it is not really the screen size that is stretched in SmartNES, because there are black bars on the sides. The benefit to ALOT of gamers in my opinion is to be able to use the controller this way. People with large hands (and others) have trouble with the "thin" setup using normal view. Please leave this mode as an option! It makes or breaks the emulator IMHO. Your emulator already kicks A$$ as far as speed and sound. I really want to play it in landscape so I can use those controls more effectively! I can't wait for the full release! Thx,
D |

One other note, I do find myself playing NES games that aren't available on the other consoles. Don't get me wrong, I play GB and GG also, but I love the NES titles just as much. If you can support NES (in landscape too!) for us retro gamers we would be in your debt. Thx again for all the hard work.

So obviously it will cause distortion:)Every one 4*4 pixels need 7 "ADD"--fast.I wander if simply cut the: 03 13 23 30 31 32 33 would make it ugly . 00 01 02 03 00 01+02/2 03 10 11 12 13 --> 10+20/2 11+12+21+22/4 13+23/2 20 21 22 23 30 31+32/2 33 30 31 32 33 this transformation also need 7 "ADD",to avoid the distortion,a 1/2 or 1/4 gene is multiplied. Larry,I do not know if it might help you. |

After testing the NES version of the emulator...all looks ok. The only glitch is the sound, all NES games have a low rumble to them that is absent from the other emulators. It is not always at the games beginning, somtimes it starts at the beginning of a level, other times on the title screen. The other emulators have perfect sound. This was tested on a Samsung i600. Thx,

deagle,
I've written a good 75% shrink routine which properly averages the pixels to get a nice looking result. This takes a bit more time and will slow things down. I released this "ugly" version to allow some feedback on the NES module such as compatibility, speed and mapper support. I need to concentrate on optimization for now and then will revisit the graphics issue. Thanks, L.B. -------------------- the fastest instructions are none at all :)

the main nes games worked a treat apart from one which had messed up graphic. tried the sms games and part of the right hand side of the screen moves to the left.

On a spvclassic the nes-games run slow and the sound is very noisy. Can you somehow make it run better....you talked about slowing it down on fast phones...does this slowdown run on all phones so that can be the reason...? If you can't I am still impressed by the gameboy and gamegear so that just great!!
And about the landscape....yes that would be very nice cause it is difficult to play more than 5 minutes else.... :wink: Can you tell anything about the release date??? I would like to by a serial now if possible. -------------------- 1. SPVclassic :-|

Hi while I think it will make the overall package look better for the non average customer, I do not feel that a NES emulator should be devoted this much time. We already have a NES emulator that works flawlessly so if there's a developer out there who is willing to work on emulators, work on the ones that currently don't work too well on Smartphone. While it would be convenient to have all these emulators in one package I just feel that Bitbank shouldn't need to focus his efforts on a system that's already been emulated to near perfection.

Thanks for the new build, BitBank. I have a few queries, though:
1. Although the NES engine was excellent, some VRC4 Games (Akumajou Denetsu) were missing the extra sound layer. Do you still plan on adding the extra sound channel to the engine? 2. Any plans for an FDS (Famicom Disk System) add-on for the emu? 3. Several games on my E100 have had corrupted sounds (sporadic static noise), particularly GBC games that are > 16M. Is this an issue of the memory/cache size of my phone? -------------------- Thanks, Nintendo Power. You f***king ruined this kid's life.

Coolbox,
Hold off on the SMS games for the moment. I have not added the graphics shrink routine yet. Larry B. -------------------- the fastest instructions are none at all :)

QUOTE well spotted! I knew there was something different :lol: Hehe thx  I hope bitbank can fix it. Cuz it is quite annoying 
btw to me it seems realy weird that a program does such a thing. How could it happen ? @ bitbank , do you think you can fix the sound problems a lot of people are reporting ? I always play with sound disabled now cuz some games make the sound realy unbearable! :roll: Ohw and do you have a releasedate already ? you can make this version the first release and then make free updates for registrered users. -------------------- Wisdom is to speak only when you can improve silence

De-GeXte,
I'm really not sure where the icon problem is coming from, but I will try to track it down. The sound problem should only be present in some of the GameBoy and NES titles due to the performance. I am working on some new ideas to speed things up and eliminate this problem. I don't want to have to sacrifice the frame rate (like SmartNES) in order to run at "full speed". L.B. -------------------- the fastest instructions are none at all :)
