This core is a analog GPU for CRTs aiming for very low subframe latency
- Very low latency (~3ms tested with GILT on GroovyMAME with frame delay 8)
- Full RGB888
- Switch all modes (progressive/interlaced) reprogramming pll according to modeline
- Connect with ethernet (can be work on wifi5/6 or Gb lan)
- Menu options: scandoubler, video position, framebuffer, ..
To install on your MiSTer you need replace MiSTer binary, so get from /hps_linux/main and copy to /media/fat of your sdcard (i think 'killall MiSTer' before copy is needed)
- Audio stream (set ON on audio core options)
- Double framebuffer for interlaced resolutions (framebuffer per field)
- More speed and stability fixes (lz4 is recommended for interlaced or 480p)
- Retroarch support for opengl/vulkan hardware rendered cores like flycast
- Dosbox-pure set 60fps on core options
- Flycast, disable threaded render on core options (or config/Flycast/Flycast.opt reicast_threaded_rendering = "disabled")
- Mednafen/Retroarch can work with arcade_31 monitor on swithres.ini
- GroovyMame MAC builds from https://github.com/djfumberger/GroovyMAME/releases/tag/2024Jan19
To install on your MiSTer you need replace MiSTer binary, so get from /test-builds/ and copy to /media/fat of your sdcard (i think 'killall MiSTer' before copy is needed)
for src details, see GroovyMAME fork by @Calamity. Now merged https://github.com/antonioginer/GroovyMAME/releases/tag/gm0261sr002z ,to activate new MiSTer backend set on command line args:
-video mister
-aspect 4:3
-switchres
-monitor arcade_15
-mister_window
-mister_ip "192.x.x.x"
-mister_compression lz4
-skip_gameinfo
-syncrefresh
-nothrottle
*Automatic frame delay is applied with frame delay 0
-mister_fd_margin 1.5/2.0/3.0 (applies a safe margin with ms to auto frame delay calculed)
*Change "uifont default" to "uifont uismall.bdf" on mame.ini for pixel perfect menu
*autosync 0 on mame.ini for menu (60hz)
for src details, see emu4crt fork https://github.com/psakhis/emu4crt ,on mednafen.cfg set:
mister.host 192.x.x.x
mister.port 32100
mister.lz4 1 (raw or lz4)
mister.vsync 0 (automatic frame delay)
video.resolution_switch mister
Menu isn't adapted, so start with retroach.exe -L cores/xxxx.dll file
on retroarch.cfg set:
mister_ip = "192.x.x.x"
mister_lz4 = "true"
video_mister_enable = "true"
*Automatic frame delay for best results on latency options
