2023-01-08	Uses eggs' fixes for dynamic audio rate control	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
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
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.
2021-08-27	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

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

2021-08-13	Adds screenshots to savestates	neonloop

2021-08-12	Adds screenshot function	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)
