mainly doing this to reduce memory footprint; we all know how nice ankerl::unordered_dense is in theory 4x faster - in practice these maps arent that "hot" anyways so not likely to have much perf gained i just want to reduce mem fragmentation to ease my porting process, plus it helps other platforms as well (ahem weak Mediatek devices) :) Signed-off-by: lizzie <lizzie@eden-emu.dev> Co-authored-by: Caio Oliveira <caiooliveirafarias0@gmail.com> Reviewed-on: https://git.eden-emu.dev/eden-emu/eden/pulls/3442 Reviewed-by: DraVee <dravee@eden-emu.dev> Reviewed-by: CamilleLaVey <camillelavey99@gmail.com> Co-authored-by: lizzie <lizzie@eden-emu.dev> Co-committed-by: lizzie <lizzie@eden-emu.dev>
