If a spawned coin lands on the same frame it hits the peak of its arc, it will never have vertical speed < 0, so it will never be collectible.
Making this also set the coin to tangible if it has 0 speed fixes this issue.
Blue coins can be collected more than once if collected on the final frame of the switch timer when BLUE_COIN_SWITCH_RETRY is enabled. Fixing this on its own isn't enough though, as the blue coin switch also doesn't check for whether that coin was collected when it resets.
This allows hack collaborators to toggle debug features such as TEST_LEVEL without the need of pushing it up and negatively impacting other hack contributors. This is also useful for general HackerSM54 development, since it may be desirable to have PUPPYPRINT_DEBUG enabled by default or to not have to worry about pushing config defines up to a development branch that risk getting merged later on.
To use, simply create a new config_local.h file and place it in the config folder. Add #pragma once to the top of the file and add all the defines you wish! If you wish for something to be undefined when it's enabled by default, simply use #undef as opposed to a commented out #define. Use a combination of #undef and #define if you wish to change an existing value of a define. This local configuration will be completely ignored if DISABLE_ALL is being used in config_debug.h.
Regarding HackerSM64 Development: All feature developers are still responsible for making sure their features work in all scenarios regardless of whatever they have toggled in this file by default. This config file may be convenient but it is not an excuse to not properly test your changes!
rnc1 has noticeably slower load times in vanilla than yay0 does. gzip and mio0 are pretty useless and can be yeeted from the repo, but that's not part of this PR's scope.
