Homebrew [Release] Handy 3DS - Atari Lynx Emulator

[nop90]

Please don't complain for bad sound. It shouldn't have been in this release.

 

[SLiV3R]

Yeah! I tried 5-10 games and they looks gorgeous on the 3ds screen. Low resolution 16 bit graphics

What is the lynx fps? My fps is around 100.. I guess it should be more like 50-60 fps.

The emulator hangs kind of often. But I guess that it will be stable soon.

I really like your menu. Perhaps you could add a second screen saver option?
Very nice work! In a couple of releases we should have a perfect lynx emulator on the 3ds

FPS should be 60 and I found a bug in FPS limiter, I'm fixing it for N3ds users.

I know how to fix sound, but I need fullspeed, so I have to decide if give priority to N3DS users (but this way I can't test the code) of first try to gain the missing FPS on O3DS.

To speedup the code a little I was thinking of converting all the emulator memory acceses to use physical words instead of phisical bytes. I'll use more memory but there is enought on 3DS. But it's a big work since there is an high risk to introduce bug and break the emulator.

Does someone if this is worth a try?

Thanks for new release.

PS : Screenshot is mine with Citra

Edit : Add screen of 0.2

Thank you for the screenshot and for posting of this emulator on other sites.

I had problems using Citra, but I solved them so now I can do screenshots on my own, Today I'll add some images of the last release.

PS: inserted new set of img from v0.2

Makes sense

... this part too

Personally I'm on a New 3DS, but I think it would be admirable to see full speed emulation on the original 3DS. In the worst-case scenario, you could always have both engines running under the hood; that way if anything breaks the user can drop back to the slower memory access. Obviously doing it at all is a lot of effort for you though, and more effort again to maintain both modes. Still, if I was an original 3DS owner I'd say "Yes, please try this, I'd love to play Lynx games at full speed."

I'm interested in how the sound will be when the fps limiter is implemented. There is a small possibility that the sound will be OK!

I'm studying the emulator intenals (Mikie module for sound) and I plan to implement the playing of the four chip channels on separate 3ds channels in a continous loop updated on the fly.

On N3DS it should work fine. Now I'm listening to original Lynx sound on youtube and it's amazing, can't wait to hear it on 3ds.

But I need time to made a clean work

2600 was my first console, so maybe in the future I could port that too.

But after Lynx there are other two emu projects in the queue.

I would die if I could play clusters revenge on the go on my N3ds

 

[nop90]

First thing I did to start v0.3 was separating the 4 channels and now the sound is better also on a o3ds compared to the previous version; tryed klax and in some points it's also clear (because there only fx sounds and not background music).

Unfortunatly had to change sound buffer size and now I have to do same tricks with the hexeditor to recover my chip's challenge saves .

You are advised, wait a little before starting the game of your life on this emu, things are changing and your saves could not be usable on future versions.

Ohshit, I'm almost halfway through Chip's Challenge already, guess I'll have to finish playing it with no sound after all
e: then again I'm not averse to hex editing..

I have to try to make a transition version that loads with the old buf size and saves with the new. If I can trick the savefile consistency check this way our, saves are not lost. I'll let you know

 

[hippy dave]

Sounds good!

This isn't an official release but a test build with little improvement:
- separated 4 sound channels
- fixed limit to 60 fps for fast cpu (n3ds)
- implemented downscaling of fps limit (nearest multiple of 5) for slow 3ds. Sound frequency is reduced accordingly
- reverted sound buffer to old value to preserve savestates

For o3ds we loose about 10 fps, but sound is a little better. Had to implement sinc by sound to elininate (I hope) crackling.

I kindly ask some n3ds users to test it and make me know if it's better now. Attached there is the 3dsx.

Nice! I will try it tomorrow morning with my n3ds

Test release freezes after about 3 minutes of play time (3 times in a row). Be nice to be able to scroll through rom list more quickly, e.g press right in d-pad to jump 10 roms. Config did not save selection for sound to remain "on" despite saving this in menu. Went back to "off" after restarting emu.

yes I know, but can't find the problem. I'm working on it.

Already planned, with other updates to the gui

Thank you, found the bug and fixed.

Great. Noticed that the emulator crashed on start up to a red screen unless cfg was predeleted every time. Maybe this fixes that also.
