2024-04-28	Adds RTC read and writeHEAD main	neonloop

2023-07-22	Opens internal file browser to last played content on core	neonloop

2023-03-15	Enables DRC on FunKey by default	neonloop
	Now that FunKey runs at 60Hz, smooth video is more meaningful
2023-01-30	Adds override for deferring load state by number of frames	neonloop
	Fixes instant play for fake-08 and pcsx_rearmmed with bios intro
2023-01-26	Forces poll for input before reading	neonloop
	Fixes arduous which reads input but never polls
2023-01-25	Fixes emu actions not able to be repeated	neonloop

2023-01-25	Fixes load new content	neonloop
	Cores do not always clean up on unload content, deinit and reinit is more reliable. Some cores do not even clean up on deinit and reinit, need all statics reinitialized. On many platforms dlclose / dlopen will work. FunKey uses musl libc where dlclose is no-op, so instead will exec again with current core and new content path. Overrides decide whether easy or hard clean up is needed. Assume unknown cores need hard cleanup, otherwise specified by "needs_reopen" override. Also - FunKey will now autosave and resume during load new content - Load new content deferred until after menu responds to keypress, otherwise key release can be missed and menu seems stuck
2023-01-25	Moves emu action response out of retro_run	neonloop
	Avoids changes to emu state in the middle of a frame, caused problem with fba and maybe rare problems with other cores
2023-01-22	Fixes instant play before first autosave is created	neonloop

2023-01-22	Moves save / config dir under .picoarch	neonloop
	Still uses old dir if exists to not need migration
2023-01-16	Adds fake-08 core	neonloop
	Includes resume state patch from shauninman, thanks! https://github.com/shauninman/picoarch/blob/miniui-miyoomini/patches/fake-08/001-fix-resume-state.patch
2023-01-15	Fixes mame2000 vector games, changes mame2000 default to aspect	neonloop

2023-01-14	Defaults aspect scaling on FunKey S to smooth filter	neonloop
	On small screen smooth looks better as default
2023-01-14	Stops fast forward before suspending	neonloop
	Prevents fast forward stuck during FunKey Instant Play
2023-01-09	Adds icons for FunKey and forces next scaler shortcut	neonloop
	Icons are downloaded when needed, for now
2023-01-09	Waits to suspend until after game loop	neonloop
	Suspending during loop caused corrupt states
2023-01-09	Uses absolute path for core	neonloop
	Fixes issue with instant play on FunKey S
2023-01-09	Adds initial Funkey S support	neonloop

2022-03-27	Changes capacity to occupancy and return whole number as percent	neonloop
	Avoids float operations and redundant "1 -"
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
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
2021-09-06	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 config override detection after loading new game	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	Adds option for CPU % display	neonloop

2021-08-21	Updates message display and adds loading message to pcsx	neonloop

2021-08-20	Adds disc control to MinUI	neonloop

2021-08-15	Moves core option changes into picoarch	neonloop
	Keeps cores cleaner and avoids conflicts
2021-08-14	Updates pcsx_rearmed core options text / defaults	neonloop

2021-08-14	Adds auto-frameskip to pcsx_rearmed	neonloop

2021-08-12	Adds screenshot function	neonloop

2021-08-12	Allows deleting game-specific config from menu	neonloop

2021-08-10	Fixes core options deallocated by core	neonloop
	Some cores free core options after notifying libretro, picoarch cannot rely on them staying around.
2021-08-10	Hides state menus if states are unsupported	neonloop

2021-08-07	Adds generic nearest and smooth scalers	neonloop
	Smooth is slower (10-15%) than a scaler built for a specific resolution. Works well for downscaling and for odd screen ratios until a custom scaler is built. Replaces the snes smooth scaler (outperforms it) and the gba smooth scaler (looks better)
2021-08-04	Initial commit	neonloop
