Also people might want to check DownRight: in custobjcode.asm and change every "DownLeft" to "DownRight" which were left there unintentionally. If you don't, have fun with your fourth to eighth 32x32 coin having its lower right tile being wrong.
For some reason the coins keep reappearing even though I've set the patch to install ObjectTool as well (which I didn't touch anywhere). The patch works really well but a solution to this would be very appreciated.
@Chillahbyte: It's doable in patch's current state. Open StarCoinsDefs.asm and search the defines !FirstPoints, !SecondPoints, and !ThirdPoints. There are comments with some information about these defines.
If the Status bar cut-offs, try reducing the maximum amount of Star Coins in a level by changing !MaxStarCoins define in StarCoinsDefs.asm.
Works flawlessly in emulators (as long as you haven't used Powertool's counter-editing patch), but LMSW refuses to let it work. Then again, I doubt LMSW compatibility is a priority with most of these patches.
