2022-03-27	Updates pcsx frameskip patch	neonloop
	Original version was reverted, now more similar to new snes9x2002 version, allows fixed_interval when buffer status callback is missing.
2022-03-27	Changes capacity to occupancy and return whole number as percent	neonloop
	Avoids float operations and redundant "1 -"
2022-03-27	Updates patches for upstream snes9x2002 changes	neonloop

2022-03-27	Adds dynamic audio rate control option	neonloop
	When DRC is on, game syncs to frame rate instead of audio buffer capacity. Audio is resampled to generate more samples when buffer is low and less when buffer is high, to keep buffer 40%-60% full. Buffer size doubled to keep same avg. audio latency value. Audio can distort when buffer is out of range, not often during gameplay. Better resampler could improve but would be slower. When buffer is always out of range (heavy frameskip), it is better to leave off, DRC doesn't help anyway then. Idea from RetroArch audio_driver.c and https://near.sh/articles/audio/dynamic-rate-control
2022-03-25	Skips main loop fb flip when screen is skipped	neonloop
	If core hasn't updated screen, no need to flip. Can save vsync delay, makes ff faster
2022-03-25	Adds passthrough resampler when core rate is supported	neonloop
	Small improvement to performance
2022-03-25	Fixes nearest scaler overrun (thanks shauninman)	neonloop

2022-02-10	Updates cores and moves to snes9x2005 fork	neonloop

2021-11-28	Adds fMSX core and builds trimui picoarch.zip	neonloop

2021-11-28	Updates cores	neonloop
	picodrive now supports GG

2021-10-21	Adds smsplus-gx core	neonloop

2021-10-21	Adds gme (Game Music Emu) core	neonloop

2021-10-20	Adds QuickNES core	neonloop

2021-10-10	Updates patches for recent changes	neonloop

2021-09-29	Fixes inability to lower audio buffer size	neonloop

2021-09-22	Skips audio writing when buffer size is 0	neonloop
	This keeps from hanging when audio is sent before content is loaded (pcsx_rearmed). picoarch cannot know correct frame rate / sample rate before content is loaded (incorrect to call retro_get_system_av_info then) so best to just skip it
2021-09-08	Avoids possible divide by zeros	neonloop

2021-09-07	Enables softpatching for cores loading content from disk	neonloop
	If a core sets need_fullpath, content is patched and written to a file in /tmp. This allows patching content for gpsp and probably others.
2021-09-07	Hide "Load new game" in mame2000	neonloop
	It breaks if you unload a game and then try to run a new game, so the option should be hidden.
2021-09-06	Adds ips/bps softpatching	neonloop
	Patches named like the content will be auto-applied in memory when the game is loaded. Example: /roms/game.gba will apply patches named /roms/game.ips, /roms/game.ips1, /roms/game.IPS2, /roms/game.bps, etc. This only happens in memory, original files are unmodified. Patches are loaded in case-insensitive alphabetical order. Note that .ips12 loads before .ips2, but after .ips02. Only supports cores that load from memory (see libretro page at https://docs.libretro.com/guides/softpatching/ for compatibility list)
2021-08-30	Adds cheat support	neonloop
	Cheats use RetroArch .cht file format. Cheats are loaded from [save_dir]/cheats/[name].cht, where name is the name of the ROM without extension. Cheat menu only shows when cheat file is found.
2021-08-28	Fixes scaler selection when dimensions are not set yet	neonloop

2021-08-28	Adds info on built-in browsers to README	neonloop

2021-08-28	Fixes config override detection after loading new game	neonloop

2021-08-27	Fixes GBA save method	neonloop
	This was not set to libretro, so SRAM was not properly written.
2021-08-27	Adds "fastest" ghosting option to gambatte	neonloop

2021-08-27	Adds eggs' 1.5x sharp scaler for GB resolutions	neonloop

2021-08-27	Adds a standalone multi-emulator mode	neonloop
	When starting without arguments, can select a core in the current directory and some content (a game). Allows loading a different game from the in-game menu.
2021-08-24	Clears buffer when switching resolutions	neonloop
	Avoids screen persistence when switching from a higher to a lower resolution.
2021-08-24	Adds option for CPU % display	neonloop

2021-08-23	Adds fceumm core	neonloop
	Needs PGO to hit fullspeed. Nestopia won't run (needs XRGB8888) and would probably be slow. Maybe try QuickNES if speed is an issue with fceumm.
2021-08-22	Adds beetle-pce-fast core	neonloop

2021-08-22	Uses libretro-common as a submodule	neonloop

2021-08-22	Fixes ordering of events when using combo keys	neonloop
	Sometimes menu would get stuck, because the simulated events would be pushed after real events. Now transform all keyboard events first, so the transform code has complete control over the order.
2021-08-21	Updates message display and adds loading message to pcsx	neonloop
