Atari Lynx Emulator

Unread post by pelle7 » Fri Jul 05, 2019 2:20 am

In the last weeks the Atari Lynx Emulator runs now some games with sound in "full speed".

My port is based on: https://github.com/libretro/libretro-handy
My repo is here: https://github.com/pelle7/go-play ; Branch: feature-lynx

Old thread: viewtopic.php?f=159&t=31558&p=261033#p260336

The SD-card must contain the file "/roms/lynx/lynxboot.img"
And the roms must be uncompressed and they must be located at: /roms/lynx/

2019-07-07 https://github.com/pelle7/odroid-go-han ... estversion

On the first startup there is a little file selector. Keys UP and DOWN. LEFT and RIGHT jumps to the next letter. On the next boot hold SELECT for selecting another game or press the MENU button.
QuickSave und QuickLoad also works. Savegame to SD-card is also supported. Audio, rotation, filter and scale configuration are stored per game.

With the volume button a little menu will popup.

On the first startup there is a little file selector. It only visualizes one row, but for testing different games it is ok. Keys UP and DOWN. LEFT and RIGHT steps with 10. On the next boot hold SELECT for selecting another game.
QuickSave und QuickLoad also works. Not to the SD-card yet.

With the volume button a little menu will popup. For now, you should only use: audio, quicksave, quickload

I will search for a game which is slow and has consistent fps.

The emulator is quite fun although some games are a little slow, but still playable (but then again I always play with sound on).
Is there a way to configure frameskip?
Or is it activated by default?

Thanks a lot for this emulator, it's quite "handy" ;)

I have added a new version: 2019-07-07.
  • I have reactivated the filtering options
  • Rotation support
  • Savegame to SD-card (include audio, scale, filter and rotate configuration
  • Modified the simple file selector
  • Modified the HOME button. Long pressing -> Savegame is created, else a popup appears
  • Audio is activated by default. If a save game exists, the configured value is used

Thank you, now I can replay Chip's Challenge 8-)

Yes, only a few games are playable with sound.

Currently frameskip is hardcoded for performance, I take a look, if can make it configurable without impacting performance.

This is amazing! I have been hoping for a Lynx emulator since I got my Go, and this works better than I hoped.
Todds Adventures In Slime World works really well without sound, allthough I cant find a button assigned to use items.
Even Hard Drivin works at playable fps (relatively speaking for 3D from that generation)!

Keep up the good work, hoping for better sound optimalization and alternative button maps in future releases!
