This patch allows you to set how many Yoshi Coins there are for each level, which when reached will give the player a 1UP, hide the coins from the status bar and set the "collected all Yoshi Coins" flag. Useful if you don't want to have 5 coins in each level, but still make them work as expected (for example, make them not respawn when getting all of them, or making stuff like overworld counters work too). You can also have more than 5 if you want, but note that the status bar counter doesn't work properly in this case (max 4 coins are displayed at once). Also it's compatible with the "Individual Dragon Coins Save" patch.
Individual Dragon Coin Save (version from 2020.07.16 in y.m.d. format)
It's a patch which exactly says on the tin. The only limitation to take care of is that you can't have more than 14 or 0xE Dragon Coins (you get one ups for the few first DCs) as well as that Individual Dragon Coin Save only allows you to preserve up to five dragon coins. The latter can be solved with an update to the latter patch, though.
